User Guide

Read this first
Be sure to follow the important tips given here to get the most use and enjoyment out of your computer.
Failure to do so might lead to discomfort or injury, or cause your computer to fail.
Protect yourself from the heat that your computer generates.
When your computer is turned on or the battery is charging, the base, the palm
rest, and some other parts may become hot. The temperature they reach
depends on the amount of system activity and the level of charge in the battery.
Extended contact with your body, even through clothing, could cause
discomfort or even a skin burn.
• Avoid keeping your hands, your lap, or any other part of your body in
contact with a hot section of the computer for any extended time.
• Periodically take hands from using the keyboard by lifting your hands from
the palm rest.

Protect yourself from the heat generated by the ac power adapter.
When the ac power adapter is connected to an electrical outlet and your
computer, it generates heat.
Extended contact with your body, even through clothing, may cause a skin
burn.
• Do not place the ac power adapter in contact with any part of your body
while it is in use.
• Never use it to warm your body.

Prevent your computer from getting wet.

To avoid spills and the danger of electrical shock, keep liquids away from your
computer.

Protect the cables from being damaged.
Applying strong force to cables may damage or break them.
Route communication lines, or the cables of an ac power adapter, a mouse, a
keyboard, a printer, or any other electronic device, so that they cannot be walked
on, tripped over, pinched by your computer or other objects, or in any way
subjected to treatment that could interfere with the operation of your computer.

Protect your computer and data when moving it.
Before moving a computer equipped with a hard disk drive, do one of the
following, and make sure that the power button is off or is blinking:
• Turn it off.
• Put it in sleep mode.
• Put it in hibernation mode.
This will help to prevent damage to the computer, and possible loss of data.

Handle your computer gently.

Do not drop, bump, scratch, twist, hit, vibrate, push, or place heavy objects on
your computer, display, or external devices.

Carry your computer carefully.

• Use a quality carrying case that provides adequate cushioning and protection.
• Do not pack your computer in a tightly packed suitcase or bag.
• Before putting your computer in a carrying case, make sure that it is off, in sleep
mode, or in hibernation mode. Do not put a computer in a carrying case while it
is turned on.

Important safety information
Note: Read the important safety information first.

This information can help you safely use your notebook computer. Follow and retain all information included
with your computer. The information in this document does not alter the terms of your purchase agreement
or the Lenovo® Limited Warranty. For more information, see “Warranty Information” in the Safety, Warranty,
and Setup Guide that comes with your computer.
Customer safety is important. Our products are developed to be safe and effective. However, personal
computers are electronic devices. Power cords, power adapters, and other features can create potential
safety risks that can result in physical injury or property damage, especially if misused. To reduce these
risks, follow the instructions included with your product, observe all warnings on the product and in the
operating instructions, and review the information included in this document carefully. By carefully following
the information contained in this document and provided with your product, you can help protect yourself
from hazards and create a safer computer work environment.
Note: This information includes references to power adapters and batteries. In addition to notebook
computers, some products (such as speakers and monitors) ship with external power adapters. If you have
such a product, this information applies to your product. In addition, computer products contain a coin-sized
internal battery that provides power to the system clock even when the computer is unplugged, so the
battery safety information applies to all computer products.

User Guide

Conditions that require immediate action
Products can become damaged due to misuse or neglect. Some product damage is serious enough
that the product should not be used again until it has been inspected and, if necessary, repaired by
an authorized servicer.
As with any electronic device, pay close attention to the product when it is turned on. On very rare
occasions, you might notice an odor or see a puff of smoke or sparks vent from your product. Or you
might hear sounds like popping, cracking or hissing. These conditions might merely mean that an
internal electronic component has failed in a safe and controlled manner. Or, they might indicate
a potential safety issue. However, do not take risks or attempt to diagnose the situation yourself.
Contact the Customer Support Center for further guidance. For a list of Service and Support phone
numbers, see the following Web site:
http://www.lenovo.com/support/phone
Frequently inspect your computer and its components for damage or wear or signs of danger.
If you have any question about the condition of a component, do not use the product. Contact
the Customer Support Center or the product manufacturer for instructions on how to inspect the
product and have it repaired, if necessary.
In the unlikely event that you notice any of the following conditions, or if you have any safety
concerns with your product, stop using the product and unplug it from the power source and
telecommunication lines until you can speak to the Customer Support Center for further guidance.
• Power cords, plugs, power adapters, extension cords, surge protectors, or power supplies that are
cracked, broken, or damaged.
• Signs of overheating, smoke, sparks, or fire.
• Damage to a battery (such as cracks, dents, or creases), discharge from a battery, or a buildup of foreign
substances on the battery.
• A cracking, hissing or popping sound, or strong odor that comes from the product.
• Signs that liquid has been spilled or an object has fallen onto the computer product, the power cord or
power adapter.
• The computer product, power cord, or power adapter has been exposed to water.
• The product has been dropped or damaged in any way.
• The product does not operate normally when you follow the operating instructions.
Note: If you notice these conditions with a product (such as an extension cord) that is not manufactured for
or by Lenovo, stop using that product until you can contact the product manufacturer for further instructions,
or until you get a suitable replacement.

Safety guidelines
Always observe the following precautions to reduce the risk of injury and property damage.

Service and upgrades
Do not attempt to service a product yourself unless instructed to do so by the Customer Support Center or
your documentation. Only use a Service Provider who is approved to repair your particular product.
Note: Some computer parts can be upgraded or replaced by the customer. Upgrades typically are
referred to as options. Replacement parts approved for customer installation are referred to as Customer
Replaceable Units, or CRUs. Lenovo provides documentation with instructions when it is appropriate for
customers to install options or replace CRUs. You must closely follow all instructions when installing or
replacing parts. The Off state of a power indicator does not necessarily mean that voltage levels inside a

vii

product are zero. Before you remove the covers from a product equipped with a power cord, always make
sure that the power is turned off and that the product is unplugged from any power source. If you have
any questions or concerns, contact the Customer Support Center.
Although there are no moving parts in your computer after the power cord has been disconnected, the
following warnings are required for your safety.

CAUTION:
Hazardous moving parts. Keep fingers and other body parts away.
CAUTION:

Before replacing any CRUs, turn off the computer and wait three to five minutes to let the computer
cool before opening the cover.

Power cords and power adapters
DANGER
Use only the power cords and power adapters supplied by the product manufacturer.
The power cords shall be safety approved. For Germany, it shall be H05VV-F, 3G, 0.75 mm2, or
better. For other countries, the suitable types shall be used accordingly.
Never wrap a power cord around a power adapter or other object. Doing so can stress the cord in
ways that can cause the cord to fray, crack, or crimp. This can present a safety hazard.
Always route power cords so that they will not be walked on, tripped over, or pinched by objects.
Protect power cords and power adapters from liquids. For instance, do not leave your power cord
or power adapter near sinks, tubs, toilets, or on floors that are cleaned with liquid cleansers.
Liquids can cause a short circuit, particularly if the power cord or power adapter has been stressed
by misuse. Liquids also can cause gradual corrosion of power cord terminals and/or the connector
terminals on a power adapter, which can eventually result in overheating.
Always connect power cords and signal cables in the correct order and ensure that all power cord
connectors are securely and completely plugged into receptacles.
Do not use any power adapter that shows corrosion at the ac input pins or shows signs of
overheating (such as deformed plastic) at the ac input pins or anywhere on the power adapter.
Do not use any power cords where the electrical contacts on either end show signs of corrosion or
overheating or where the power cord appears to have been damaged in any way.

viii

User Guide

To prevent possible overheating, do not cover the power adapter with clothing or other objects
when the power adapter is plugged into an electrical outlet.

Extension cords and related devices
Ensure that extension cords, surge protectors, uninterruptible power supplies, and power strips that you use
are rated to handle the electrical requirements of the product. Never overload these devices. If power strips
are used, the load should not exceed the power strip input rating. Consult an electrician for more information
if you have questions about power loads, power requirements, and input ratings.

Plugs and outlets
DANGER
If a receptacle (power outlet) that you intend to use with your computer equipment appears to be
damaged or corroded, do not use the outlet until it is replaced by a qualified electrician.
Do not bend or modify the plug. If the plug is damaged, contact the manufacturer to obtain
a replacement.
Do not share an electrical outlet with other home or commercial appliances that draw large amounts
of electricity; otherwise, unstable voltage might damage your computer, data, or attached devices.
Some products are equipped with a three-pronged plug. This plug fits only into a grounded
electrical outlet. This is a safety feature. Do not defeat this safety feature by trying to insert it into
a non-grounded outlet. If you cannot insert the plug into the outlet, contact an electrician for an
approved outlet adapter or to replace the outlet with one that enables this safety feature. Never
overload an electrical outlet. The overall system load should not exceed 80 percent of the branch
circuit rating. Consult an electrician for more information if you have questions about power loads
and branch circuit ratings.
Be sure that the power outlet you are using is properly wired, easily accessible, and located close
to the equipment. Do not fully extend power cords in a way that will stress the cords.
Be sure that the power outlet provides the correct voltage and current for the product you are
installing.
Carefully connect and disconnect the equipment from the electrical outlet.

Power supply statement
DANGER
Never remove the cover on a power supply or any part that has the following label attached.

Hazardous voltage, current, and energy levels are present inside any component that has this label
attached. There are no serviceable parts inside these components. If you suspect a problem with
one of these parts, contact a service technician.

External devices
CAUTION:
Do not connect or disconnect any external device cables other than USB cables while the computer
power is on; otherwise, you might damage your computer. To avoid possible damage to attached
devices, wait at least five seconds after the computer is shut down to disconnect external devices.

General battery notice
DANGER
Personal computers manufactured by Lenovo contain a coin-cell battery to provide power to
the system clock. In addition, many mobile products, such as notebook computers, utilize a
rechargeable battery pack to provide system power when in portable mode. Batteries supplied by
Lenovo for use with your product have been tested for compatibility and should only be replaced
with approved parts.
Never attempt to open or service any battery. Do not crush, puncture, or incinerate batteries or
short circuit the metal contacts. Do not expose the battery to water or other liquids. Only recharge
the battery pack strictly according to instructions included in the product documentation.
Battery abuse or mishandling can cause the battery to overheat, which can cause gasses or flame
to “vent” from the battery pack or coin cell. If your battery is damaged, or if you notice any
discharge from your battery or the buildup of foreign materials on the battery leads, stop using the
battery and obtain a replacement from the battery manufacturer.
Batteries can degrade when they are left unused for long periods of time. For some rechargeable
batteries (particularly Lithium Ion batteries), leaving a battery unused in a discharged state could
increase the risk of a battery short circuit, which could shorten the life of the battery and also can
pose a safety hazard. Do not let rechargeable Lithium-Ion batteries completely discharge or store
these batteries in a discharged state.

Notice for lithium coin-cell battery
DANGER
Danger of explosion if battery is incorrectly replaced.
Do not:
• Throw or immerse into water
• Heat to more than 100°C (212°F)
• Repair or disassemble
Dispose of the battery as required by local ordinances or regulations.
The following statement applies to users in the state of California, U.S.A.
California Perchlorate Information:

User Guide

Products containing manganese dioxide lithium coin cell batteries may contain perchlorate.
Perchlorate Material - special handling may apply, See
www.dtsc.ca.gov/hazardouswaste/perchlorate

Rechargeable battery notice
DANGER
Do not attempt to disassemble or modify the battery pack. Attempting to do so can cause an
explosion, or liquid leakage from the battery pack. A battery pack other than the one specified by
Lenovo, or a disassembled or modified battery pack is not covered by the warranty.
If the rechargeable battery pack is incorrectly replaced, there is danger of an explosion. The battery
pack contains a small amount of harmful substances. To avoid possible injury:

Heat and product ventilation
DANGER
Computers, ac power adapters, and many accessories can generate heat when turned on and when
batteries are charging. Notebook computers can generate a significant amount of heat due to their
compact size. Always follow these basic precautions:
• When your computer is turned on or the battery is charging, the base, the palm rest, and some
other parts may become hot. Avoid keeping your hands, your lap, or any other part of your
body in contact with a hot section of the computer for any extended length of time. When you
use the keyboard, avoid keeping your palms on the palm rest for a prolonged period of time.
Your computer generates some heat during normal operation. The amount of heat depends on
the amount of system activity and the battery charge level. Extended contact with your body,
even through clothing, could cause discomfort or even a skin burn. Periodically take breaks
from using the keyboard by lifting your hands from the palm rest; and be careful not to use
the keyboard for any extended length of time.
• Do not operate your computer or charge the battery near flammable materials or in explosive
environments.

• Ventilation slots, fans and/or heat sinks are provided with the product for safety, comfort, and
reliable operation. These features might inadvertently become blocked by placing the product on
a bed, sofa, carpet, or other flexible surface. Never block, cover, or disable these features.
• When the ac power adapter is connected to an electrical outlet and your computer, it generates
heat. Do not place the adapter in contact with any part of your body while using it. Never use the
ac power adapter to warm your body. Extended contact with your body, even through clothing,
may cause a skin burn.
For your safety, always follow these basic precautions with your computer:
• Keep the cover closed whenever the computer is plugged in.
• Regularly inspect the outside of the computer for dust accumulation.
• Remove dust from vents and any perforations in the bezel. More frequent cleanings might be
required for computers in dusty or high-traffic areas.
• Do not restrict or block any ventilation openings.

Locating important product information
This section provides information to help you locate the machine type and model label, the FCC ID and IC
Certification label, the Windows Certificate of Authenticity label, and the Genuine Microsoft® label.

Machine type and model information
The machine type and model label identifies your computer. When you contact Lenovo for help, the machine
type and model information helps support technicians to identify your computer and provide faster service.
The following figure shows the location of the machine type and model of your computer.

FCC ID and IC Certification information
There is no FCC ID or IC Certification number for the wireless communication cards shown on the enclosure
of the computer. The FCC ID and IC Certification number label is affixed on the card installed in the
wireless-communication-card slot of the computer. Lenovo provides you the information about the location
of the FCC ID and IC Certification number label on the computer back cover assembly.
The following figure shows the information about the locations of the FCC ID and IC Certification number
labels.

User Guide

The FCC ID and IC Certification number labels are affixed on the wireless-LAN card 1 and wireless-WAN
card 2 installed in your computer.

Note: Use only Lenovo-authorized wireless communication cards for the computer. If you install an
unauthorized wireless communication card that is not approved for use in your computer, an error message
will be displayed and the computer will beep when you turn on the computer.

Labels for the Windows operating systems
Windows 7 Certificate of Authenticity: Computer models preinstalled with the Windows 7 operating
system have a Certificate of Authenticity label affixed to the computer cover or inside the battery
compartment. The Certificate of Authenticity is your indication that the computer is licensed for a Windows 7
product and is preinstalled with a Windows 7 genuine version. In some cases, an earlier Windows version
might be preinstalled under the terms of the Windows 7 Professional license downgrade rights. Printed on
the Certificate of Authenticity is the Windows 7 version for which the computer is licensed and the Product
ID. The Product ID is important in case you need to reinstall the Windows 7 operating system from a source
other than a Lenovo product recovery disc set.
Windows 8, Windows 8.1, and Windows 10 Genuine Microsoft label: Depending on your geographic
location, the date when your computer was manufactured, and the version of Windows 8, Windows 8.1,
or Windows 10 that is preinstalled, your computer might have a Genuine Microsoft label affixed to its
cover. See http://www.microsoft.com/en-us/howtotell/Hardware.aspx for illustrations of the various types
of Genuine Microsoft labels.
• In the People’s Republic of China, the Genuine Microsoft label is required on all computer models
preinstalled with any version of Windows 8, Windows 8.1, or Windows 10.

Chapter 1. Product overview

• In other countries and regions, the Genuine Microsoft label is required only on computer models licensed
for Windows 8 Pro, Windows 8.1 Pro, or Windows 10 Pro.
The absence of a Genuine Microsoft label does not indicate that the preinstalled Windows version is not
genuine. For details on how to tell whether your preinstalled Windows product is genuine, refer to the
information provided by Microsoft at http://www.microsoft.com/en-us/howtotell/default.aspx.
Unlike Windows 7 products, there are no external, visual indicators of the Product ID or Windows version for
which the computer is licensed. Instead, the Product ID is recorded in the computer firmware. Whenever a
Windows 8, Windows 8.1, or Windows 10 product is installed, the installation program checks the computer
firmware for a valid, matching Product ID to complete the activation.
In some cases, an earlier Windows version might be preinstalled under the terms of the Windows 8 Pro,
Windows 8.1 Pro, or Windows 10 Pro license downgrade rights.

An introduction to Lenovo programs
This topic provides a brief introduction to Lenovo programs. Depending on your computer model, some of
the programs might not be available.
Access Connections™
(Windows 7)

The Access Connections program is a connectivity assistant program for
creating and managing location profiles. Each location profile stores all the
network and Internet configuration settings needed for connecting to a network
infrastructure from a specific location such as a home or an office.
By switching between location profiles as you move your computer from place
to place, you can quickly and easily connect to a network with no need to
manually reconfigure your settings and restart the computer each time.

Active Protection System™
(Windows 7, Windows 8, Windows
8.1, and Windows 10)

The Active Protection System program protects your internal storage drive (such
as hard disk drive) when the shock sensor inside your computer detects a
condition that could damage the drive, such as system tilt, excessive vibration,
or shock.
The internal storage drive is less vulnerable to damage when it is not operating.
This is because when the internal storage drive is not operating, the system
stops it from spinning, and might also move the read and write heads of the
drive to areas that do not contain data.
As soon as the shock sensor senses that the environment is stable again
(minimal change in system tilt, vibration, or shock), it turns on the internal
storage drive.

Power management
When you need to use your computer away from electrical outlets, you depend on battery power to keep
your computer running. Different computer components consume power at different rates. The more you
use the power-intensive components, the faster you consume battery power.
Spend more time unplugged with ThinkPad batteries. Mobility has revolutionized business by enabling
you to take your work wherever you go. With ThinkPad batteries, you will be able to work longer without
being tied to an electrical outlet.

Checking the battery status
Move your pointer to the battery-status icon in the Windows notification area to check the battery status.
The battery-status icon displays the percentage of battery power remaining and how long you can use
your computer before you must charge the battery.
The rate at which you use battery power determines how long you can use the battery of your computer
between charges. Because of different user habits and needs, it is difficult to predict how long a battery
charge will last. There are two main factors:
• How much energy is stored in the battery when you begin to work.
• The way you use your computer. For example:
32

User Guide

– How often you access the hard disk drive or solid-state drive.
– How bright you make the computer display.
– How often you use the wireless features.
Enabling the battery alarm on the Windows 7 operating system

operation, when the message is displayed, click OK.

Using the ac power adapter
The power to run your computer can come either from the lithium-ion (Li-ion) battery, or from ac power
through the ac power adapter. While you use ac power, the battery charges automatically.
The ac power adapter that comes with your computer has two basic components:
• The transformer pack that converts ac power for use with the computer.
• The power cord that plugs into the ac outlet and into the transformer pack.
Attention: Using an improper power cord might cause severe damage to your computer.
Connecting the ac power adapter
To connect the ac power adapter, do the following:
Note: Ensure that you perform the actions in the order in which they are listed.
1. Connect the power cord to the transformer pack.
2. Connect the ac power adapter to the ac power connector of the computer.
3. Plug the ac power adapter into an electrical outlet.
Tips for using the ac power adapter
• When the ac power adapter is not in use, disconnect it from the electrical outlet.
• Do not bind the power cord tightly around the ac power adapter transformer pack when it is connected to
the transformer.
• Before you charge the battery, make sure that its temperature is at least 10°C (50°F).
• You can charge the battery when the ac power adapter is connected to the computer. You need to
charge the battery in any of the following situations:
– When the battery icon in the Windows notification area shows a low percentage of battery power
remaining.
– When the battery has not been used for a long time

Chapter 2. Using your computer

Charging the battery
When you check battery status and find that the percentage of power remaining is low or when the power
alarm alerts you that the remaining power is low, you need to charge your battery.
If an ac outlet is convenient, plug the ac power adapter into it, and then connect the ac power adapter to the
computer. The battery will be fully charged in about three to six hours. The charging time is affected by the
battery size and the physical environment. You can check the battery charging status at any time through the
battery-status icon in the Windows notification area.
Note: To maximize the life of the battery, the computer does not start recharging the battery if the remaining
power is greater than 95%.

Maximizing the battery life
To maximize the life of the battery, do the following:
• Use the battery until the charge is completely depleted.
• Recharge the battery completely before using it. You can see whether the battery is fully charged from the
battery-status icon in the Windows notification area.
• Always use power-saving modes, such as sleep mode, and hibernation mode.

Managing the battery power
To achieve the best balance between performance and power saving, adjust your power plan settings
by doing the following:
1. Go to Control Panel, then change the view of Control Panel from Category to Large icons or Small icons.
2. Click Power Options.
3. Follow the instructions on the screen.
For more information, refer to the help information system of the program.

caused by long periods of working in the same position. Frequent short breaks from your work also help
to prevent minor discomfort associated with your working posture.
Display: Position the display to maintain a comfortable viewing distance of 510-760 mm (20-30 inches).
Avoid glare or reflections on the display from overhead lighting or outside sources of light. Keep the display
screen clean and set the brightness to levels that enable you to see the screen clearly. Press F5 or F6
to adjust display brightness.
Head position: Keep your head and neck in a comfortable and neutral (vertical, or upright) position.
Chair: Use a chair that gives you good back support and seat height adjustment. Use chair adjustments to
best suit your desired posture.

Arm and hand position: Keep your forearms, wrists, and hands in a relaxed and neutral (horizontal) position.
Type with a soft touch without pounding the keys.
Leg position: Keep your thighs parallel to the floor and your feet flat on the floor or on a footrest.
What if you are traveling?
It might not be possible to observe the best ergonomic practices when you are using your computer while
on the move or in a casual setting. Regardless of the setting, try to observe as many of these tips as
possible. Sitting properly and using adequate lighting, for example, will help you maintain desirable levels
of comfort and performance.
Questions about vision?
The visual display screens of ThinkPad notebook computers are designed to meet the highest standards
and to provide you with clear, crisp images and large, bright displays that are easy to see, yet easy on the
eyes. Of course, any concentrated and sustained visual activity can be tiring. If you have questions on eye
fatigue or visual discomfort, consult a vision care specialist for advice.

Comfort
Observe the following guidelines to achieve greater comfort and improve performance.
Active sitting and rest breaks: The longer you sit and work with your computer, the more important it is to
observe your working posture. Follow “Ergonomic information” on page 53 and practice “active sitting” to
avoid discomfort associated with your working postures. Making minor voluntary postural changes and
taking short frequent work breaks are the key ingredients for healthy computing. Your computer is light and
mobile; you can easily reposition your working surface to accommodate many posture modifications.
Work area setup options: Familiarize yourself with all of your office furniture so that you know how to adjust
your work surface, seat, and other work tools to accommodate your preferences for comfort. If your work
area is not in an office setting, be sure to take special note of employing active sitting and taking work
breaks. Many ThinkPad product solutions are available to help you modify and expand your computer to
best suit your needs. You can find some of these options at http://www.lenovo.com/essentials. Explore your

Notice on deleting data from your hard disk drive or solid-state drive
Some of the data stored on the hard disk drive or solid-state drive might be sensitive. Handing your
computer over to someone else without deleting the loaded software, such as operating systems and
application software, might even violate license agreements. Be sure to delete data stored on the hard disk
drive or solid-state drive before you dispose of, sell, or hand over your computer.
You can use the following methods to delete data from the hard disk drive or solid-state drive:
• Move the data to the Recycle Bin, and then emptying the Recycle Bin.
• Delete the data.
• Format your hard disk drive or solid-state drive, using the software for initializing it.
• Use the recovery program provided by Lenovo to bring the hard disk drive or solid-state drive back to
the factory default settings.
These operations, however, only change the file location of the data; they do not delete the data itself. In
other words, the data retrieval processing is disabled under an operating system such as Windows. The
data is still there, even though it seems to be lost. Thus, it is sometimes possible to read the data by use of
special software for data recovery. There is a risk that people of bad faith might read and misuse the critical
data on hard disk drives or solid-state drives for unexpected purposes.
To prevent leakage of data, it is important that you delete all the data from the hard disk drive when you
dispose of, sell, or hand over your computer. You can destroy the data physically by smashing the hard disk
drive with a hammer, or magnetically by means of strong magnetic power, thus making the data unreadable.
But it is recommended that you use the software (payware) or service (pay service) developed for that
purpose. The process might take several hours.
For disposing of data on the solid-state drive, Lenovo provides the Drive Erase Utility for Resetting the
Cryptographic Key and Erasing the Solid State Drive tool. For disposing of data on the hard disk drive, Lenovo
provides the Secure Data Disposal™ tool. Go to http://www.lenovo.com/support to download the tool.
If an Encryption solid-state drive or a Disk Encryption hard disk drive is supported and installed in your
computer, you can logically dispose of all the data on the drive in a short time by erasing the cryptographic
Chapter 5. Security

key. The data encrypted with the old key is not physically erased but remains on the drive; however, it cannot
be decrypted without the old key. This feature is also available with the Drive Erase Utility for Resetting the
Cryptographic Key and Erasing the Solid State Drive tool.

Using firewalls
If your system is preinstalled with a firewall program, it protects against computer Internet security threats,
unauthorized accesses, intrusions, and Internet attacks. It also protects your privacy.
For more information about how to use the firewall program, refer to the help information system that
comes with the program.

Protecting data against viruses
Your computer is preinstalled with an antivirus program so you can detect and eliminate viruses. The
antivirus program is designed to help you detect and eliminate viruses.
Lenovo provides a full version of antivirus software on your computer with a free 30-day subscription. After
30 days, you must renew the license to continue receiving the antivirus software updates.
For more information about how to use your antivirus software, refer to the help information system of
your antivirus software.

Updating the UEFI BIOS
The UEFI BIOS is the first program that the computer runs when the computer is turned on. The UEFI BIOS
initializes the hardware components, and loads the operating system and other programs.
You can update the UEFI BIOS by starting your computer from a flash update optical disc or a flash update
program running in the Windows environment. When you install a new program, a device driver, or hardware,
you might be informed to update the UEFI BIOS.
For instructions on how to update the UEFI BIOS, go to:
http://www.lenovo.com/ThinkPadDrivers

Using system management
This topic is primarily intended for network administrators.
Your computer is designed for manageability, so that you can redirect more resources to better meet
your business objectives.
This manageability, known as Total Cost of Ownership (TCO), enables you to remotely operate client
computers in the same way as you operate your own computer, such as turning on a client computer,
formatting a hard disk drive, and installing a program.
Once the computer is configured and operational, you can manage it by using the software and the
manageability features that are already integrated into the client computer and the network.
Desktop Management Interface
The UEFI BIOS of your computer supports an interface called System Management BIOS (SMBIOS)
Reference Specification, version 2.7.1. SMBIOS provides information about the hardware components of
your computer. It is the responsibility of the UEFI BIOS to provide information about itself and the devices on
the system board. This specification documents the standards for getting access to this BIOS information.
Preboot eXecution Environment
The Preboot eXecution Environment (PXE) technology makes the computer more manageable by enabling
the computer to start from a server. Your computer supports the personal computer functions that PXE
requires. For example, with the appropriate LAN card, your computer can be started from the PXE server.
Note: The Remote Initial Program Load (RIPL or RPL) function cannot be used with your computer.
Wake on LAN
The network administrator can turn on a computer from a management console by using the Wake on
LAN feature.

Chapter 6. Advanced configuration

When the Wake on LAN feature is enabled, many operations, such as data transfer, software updates, and
Flash updates of the UEFI BIOS, can be done remotely without remote attendance. The updating process
can perform after normal working hours and on weekends, so that the users are not interrupted during work,
and the LAN traffic is kept to a minimum. It saves time and increases productivity.
Note: If the computer is turned on through Wake on LAN, the computer starts follow the Network Boot
sequence.
Asset ID EEPROM
The Asset ID EEPROM contains information about the computer configuration and the serial numbers of
the key components. It also includes a number of blank fields where you can record information about
the end users in your network.

Setting management features
To enable a network administrator to remotely control your computer, set the following system-management
features in the ThinkPad Setup program:
• Wake on LAN
• Network Boot sequence
• Flash update
Note: If a supervisor password has been set, you will be required to enter the supervisor password when
you start the ThinkPad Setup program.
Enabling or disabling the Wake on LAN feature
When the Wake on LAN feature is enabled and the computer is connected to a LAN, the network administrator
can start the computer remotely from a management console, using a remote network-management program.
To enable or disable the Wake on LAN feature, do the following:
1. Start the ThinkPad Setup program. See “Using the ThinkPad Setup program” on page 71.
2. Select Config ➙ Network. The Network submenu is displayed.
3. Select a corresponding option for the Wake on LAN feature.
4. Press F10 to save and exit.
Defining a Network Boot sequence
When the computer wakes on LAN, the computer starts from the device as specified on the Network Boot
menu, and then follow the boot order list on the Boot menu.
To define a Network Boot sequence, do the following:
1. Start the ThinkPad Setup program. See “Using the ThinkPad Setup program” on page 71.
2. Select Startup ➙ Network Boot. The boot device list is displayed.
3. Select a boot device to make it as the top boot priority.

General tips for preventing problems
This topic provides the following tips to help you prevent computing problems:
• If your computer is equipped with both a hard disk drive and an M.2 solid-state drive, you are not
recommended to use the M.2 solid-state drive as a bootable device. The M.2 solid-state drive is designed
and developed for the “cache” function purpose only. If you use the M.2 solid-state drive as a bootable
device, its reliability is not guaranteed.
• Check the capacity of your hard disk drive from time to time. If the hard disk drive gets too full, the
Windows operating system will slow down and might produce errors.
To check the hard disk drive capacity, do the following:
– Windows 7: Click Start ➙ Computer.
– Windows 8 and Windows 8.1: Open the File Explorer and click Computer.
– Windows 10: Open the File Explorer and click This PC.
• Empty your recycle bin on a regular basis.
• Use disk defragment tool regularly on your hard disk drive to improve data seek and read times.
• To free up disk space, uninstall unused programs.
Note: You also might want to look for program duplication or overlapping versions.
• Clean out your Inbox, Sent, and Trash folders from your e-mail client program.
• Back up your data at least once a week. If critical data is present, it is a good idea to perform a daily
backup operation. Lenovo has many backup options available for your computer. Rewritable optical
drives are available for most machines and are easily installed.
• Schedule system restore operations to take a system snapshot periodically. For more information about
system restore, see Chapter 9 “Recovery overview” on page 111.
• Update device drivers and UEFI BIOS when needed.
• Profile your machine at http://www.lenovo.com/support to keep up to date with current drivers and
revisions.
• Keep up to date for device drivers on other non-Lenovo hardware. You might want to read the device
driver information release notes prior to updating for compatibility or known issues.
• Keep a log book. Entries might include major hardware or software changes, driver updates, minor issues
you have experienced, and how you resolved the minor issues.
• If you ever need to run a recovery on your computer to return the preinstalled contents onto the machine,
the following tips might help along the way:
– Remove all external devices such as the printer, keyboard, and so on.
– Make sure that your battery is charged and your computer has the ac power connected.

– Access ThinkPad Setup and load the default settings.
– Restart the computer and start the recovery operation.
– If your computer uses discs as the recovery media, do not remove the disc from the drive until
prompted to do so.
• For suspected hard disk drive issues, refer to “Diagnosing problems” on page 93 and run a diagnostic
test for the drive before you call the Customer Support Center. If your computer does not start up,
download the files to create a bootable self-test medium from http://www.lenovo.com/hddtest. Run the
test and record any messages or error codes. If the test returns any failing error codes or messages,
call the Customer Support Center with the codes or messages and the computer in front of you. A
technician will assist you further.
• If required, you can find the contact information about the Customer Support Center for your country
or region at http://www.lenovo.com/support/phone. When calling the Customer Support Center, make
sure that you have your machine model type, serial number, and the computer in front of you. Also, if the
computer is producing error codes, it is helpful to have the error screen on or the messages written down.

Making sure device drivers are up-to-date
Device drivers are programs that contain instructions for the operating system about how to operate or
“drive” a certain piece of hardware. Each hardware component on your computer has its own specific driver.
If you add a new component, the operating system needs to be instructed on how to operate that piece
of hardware. After you install the driver, the operating system can recognize the hardware component
and understand how to use it.
Note: Because drivers are programs, like any other file on your computer, they are susceptible to corruption
and might not perform correctly if corruption occurs.
It is not always necessary to download the latest drivers. However, you should download the latest driver
for a component if you notice poor performance from that component or if you added a new component.
This might eliminate the driver as the potential cause of a problem.
Getting the latest drivers from the Web site
You can download and install updated device drivers from the Lenovo Web site by doing the following:
1. Go to http://www.lenovo.com/ThinkPadDrivers.
2. Select the entry for your computer and then follow the instructions on the screen to download and
install necessary software.
Getting the latest drivers using System Update
The System Update program helps you keep the software on your computer up-to-date. Update packages
are stored on Lenovo servers and can be downloaded from the Lenovo Support Web site. Update packages
can contain applications, device drivers, UEFI BIOS flashes, or software updates. When the System Update
program connects to the Lenovo Support Web site, the System Update program automatically recognizes
the machine type and model of your computer, the installed operating system, and the language of the
operating system to determine what updates are available for your computer. The System Update program
then displays a list of update packages and categorizes each update as critical, recommended, or optional to
help you understand the importance. You have complete control of which updates to download and install.
After you select the update packages you want, the System Update program automatically downloads and
installs the updates without any further intervention from you.
The System Update program is preinstalled on your computer and is ready to run. The only prerequisite is
an active Internet connection. You can start the program manually, or you can use the schedule feature
to enable the program to search for updates automatically at specified intervals. You also can predefine

User Guide

scheduled updates to search by severity (critical updates, critical and recommended updates, or all updates)
so the list you choose from contains only those update types that are of interest to you.
For more information about how to use the System Update program, refer to the help information system
of the program.

Taking care of your computer
Although your computer is designed to function reliably in normal work environments, you need to use
common sense in handling it. By following the important tips in this topic, you will get the most use and
enjoyment out of your computer.
Be careful about where and how you work
• Store packing materials safely out of the reach of children to prevent the risk of suffocation from plastic
bags.
• Keep your computer away from magnets, activated cellular phones, electrical appliances, or speakers
(more than 13 cm or 5 inches).
• Avoid subjecting your computer to extreme temperatures (below 5°C/41°F or above 35°C/95°F).
• Some appliances, such as certain portable desktop fans or air purifiers, can produce negative ions. If a
computer is close to such an appliance, and is exposed for an extended time to air containing negative
ions, it might become electrostatically charged. Such a charge might be discharged through your hands
when you touch the keyboard or other parts of the computer, or through connectors on I/O devices
connected to the computer. Even though this kind of electrostatic discharge (ESD) is the opposite of a
discharge from your body or clothing to the computer, it poses the same risk of a computer malfunction.
Your computer is designed and manufactured to minimize any effects of electrostatic charge. An electrostatic
charge above a certain limit, however, can increase the risk of ESD. Therefore, when using the computer
close to an appliance that can produce negative ions, give special attention to the following:
• Avoid directly exposing your computer to the air from an appliance that can produce negative ions.
• Keep your computer and peripherals as far as possible from such an appliance.
• Wherever possible, ground your computer to facilitate safe electrostatic discharge.
Note: Not all such appliances cause a significant electrostatic charge.
Be gentle with your computer
• Avoid placing any objects (including paper) between the display and the keyboard or the palm rest.
• Your computer lid is designed to be opened and used at an angle slightly greater than 90 degrees. Do not
open the display beyond 180 degrees, as this might damage the computer hinge.
• Do not turn your computer over while the ac power adapter is plugged in. This could break the adapter
plug.
Carry your computer properly
• Before moving your computer, be sure to remove any media, turn off attached devices, and disconnect
cords and cables.
• When picking up your open computer, hold it by the bottom. Do not pick up or hold your computer by
the display.
Handle storage media and drives properly
• If your computer comes with an optical drive, do not touch the surface of a disc or the lens on the tray.
• Wait until you hear the CD or DVD click into the center pivot of the drive before closing the tray.
Chapter 7. Preventing problems

• On your computer, use only optical drives designed for use with the Serial Ultrabay Enhanced bay.
• When installing the hard disk drive, solid-state drive, or optical drive, follow the instructions shipped with
your hardware, and apply pressure only where needed on the device.
• Turn off your computer before you replace the hard disk drive or solid-state drive.
• After you replace the primary hard disk drive or solid-state drive, reattach the cover of the drive slot.
• Store your external and removable hard disk drive or optical drives in the appropriate containers or
packaging when they are not being used.
• Before you install a memory card such as an SD card, SDHC card, SDXC card, and a MultiMediaCard,
touch a metal table or a grounded metal object. This action reduces any static electricity from your
body. Static electricity could damage the device.
• While transferring data to or from a flash media card, such as an SD card, do not put your computer into
sleep or hibernation mode before the data transfer is complete; otherwise, your data could become
damaged.
Take care in setting passwords
• Remember your passwords. If you forget a supervisor or hard disk password, Lenovo will not reset it, and
you might have to replace your system board, or hard disk drive or solid-state drive.
Taking care of the fingerprint reader
The following actions could damage the fingerprint reader or cause it not to work properly:
• Scratching the surface of the fingerprint reader with a hard, pointed object.
• Scraping the surface of the fingerprint reader with your fingernail or anything hard.
• Using or touching the fingerprint reader with a dirty finger.
If you notice any of the following conditions, gently clean the surface of the fingerprint reader with a dry,
soft, lint-free cloth:
• The surface of the fingerprint reader is dirty or stained.
• The surface of the fingerprint reader is wet.
• The fingerprint reader often fails to enroll or authenticate your fingerprint.
Register your computer
• Register your ThinkPad computer with Lenovo at http://www.lenovo.com/register. For more information,
see “Registering your computer” on page 23.
Be sure not to modify your computer
• Only an authorized ThinkPad repair technician should disassemble and repair your computer.
• Do not modify or tape the latches to keep the display open or closed.

Cleaning the cover of your computer
Occasionally clean your computer by doing the following:
1. Prepare a mixture of a gentle kitchen-use detergent. The detergent must not contain abrasive powder or
strong chemicals such as acid or alkaline. Use five parts water to one part detergent.
2. Absorb the diluted detergent into a sponge.
3. Squeeze excess liquid from the sponge.
4. Wipe the cover with the sponge, using a circular motion and taking care not to let any excess liquid drip.
5. Wipe the surface to remove the detergent.

User Guide

6. Rinse the sponge with clean running water.
7. Wipe the cover with the clean sponge.
8. Wipe the surface again with a dry, soft, lint-free cloth.
9. Wait for the surface to dry completely and remove any fibers from the cloth.
Cleaning your computer keyboard
To clean the computer keyboard, do the following:
1. Apply some isopropyl rubbing alcohol to a soft, dust-free cloth.
Note: Avoid spraying cleaner directly onto the keyboard.
2. Wipe each keytop surface with the cloth. Wipe the keys one by one; if you wipe several keys at a time,
the cloth might hook onto an adjacent key and possibly damage it. Make sure that no liquid drips onto
or between the keys.
3. Allow to dry.
4. To remove any crumbs or dust from beneath the keys, you can use a camera blower with a brush
or cool air from a hair dryer.
Cleaning your computer display
To clean the computer display, do the following:
1. Gently wipe the display with a dry, soft lint-free cloth. If you see a scratchlike mark on your display, it
might be a stain transferred from the keyboard or the TrackPoint pointing stick when the cover was
pressed from the outside.
2. Wipe or dust the stain gently with a soft, dry cloth.
3. If the stain remains, moisten a soft, lint-free cloth with water or a 50-50 mixture of isopropyl alcohol and
water that does not contain impurities.
Note: Avoid spraying cleaner directly onto the keyboard.
4. Wring out as much of the liquid as you can.
5. Wipe the display again; do not let any liquid drip into the computer.
6. Be sure to dry the display before closing it.

Recovery overview for the Windows 7 operating system
This section provides information about the recovery solutions provided by Lenovo on the Windows 7
operating system.
Notes:
• There are a variety of methods to choose from when considering how to recover in the event of a
software-related or hardware-related problem. Some methods vary depending on the type of your
operating system.
• The product on the recovery media might be used only for the following purposes:
– Restore the product preinstalled on your computer
– Reinstall the product
– Modify the product using the Additional Files
To prevent potential performance risks or unexpected behavior that might be caused by the new hard disk
drive technology, it is recommended that you use one of the following back-up software programs:
• Rescue and Recovery version 4.3 or later
• Acronis True Image 2010 or later
• Paragon Backup & Recovery 10 Suite or later, Paragon Backup & Recovery 10 Home or later

Creating and using recovery media
You can use recovery media to restore the hard disk drive to the factory default settings. Recovery media
are useful if you transfer the computer to another area, sell the computer, recycle the computer, or put the
computer in an operational state after all other methods of recovery have failed. As a precautionary measure,
it is important to create recovery media as early as possible.
Note: The recovery operations you can perform using recovery media vary depending on the operating
system from which the recovery media were created. The recovery media might contain a boot medium
and a data medium. Your Microsoft Windows license permits you to create only one data medium, so it is
important that you store the recovery media in a safe place after you have made them.
Creating recovery media
This section provides instructions on how to create recovery media.
You can create recovery media using discs or external USB storage devices. To create recovery media,
you need a disc or USB storage device with at least 16 GB of storage. The required disc or USB capacity
depends on the size of the recovery image.
Attention: Creating recovery media will delete anything stored on the disc or USB storage device. To avoid
data loss, make a backup copy of all the data that you want to keep.

Using the Rescue and Recovery workspace
The Rescue and Recovery workspace resides in a protected, hidden area of your hard disk drive that
operates independently from the Windows operating system. It enables you to perform recovery operations
even if you cannot start the Windows operating system. You can perform the following recovery operations
from the Rescue and Recovery workspace:
• Rescue files from your hard disk drive or from a backup
The Rescue and Recovery workspace enables you to locate files on your hard disk drive and transfer
them to a network drive or other recordable media, such as a USB device or a disc. This solution is
available even if you did not back up your files or if changes were made to the files since your last backup
operation. You also can rescue individual files from a Rescue and Recovery backup located on your local
hard disk drive, a USB device, or a network drive.
• Restore your hard disk drive from a Rescue and Recovery backup
If you have backed up your hard disk drive using the Rescue and Recovery program, you can restore the
hard disk drive from a Rescue and Recovery backup, even if you cannot start the Windows operating
system.
• Restore your hard disk drive to the factory default settings
The Rescue and Recovery workspace enables you to restore the complete contents of your hard disk drive
to the factory default settings. If you have multiple partitions on your hard disk drive, you have the option
to restore the factory default settings to the C: partition and leave the other partitions intact. Because the
Rescue and Recovery workspace operates independently from the Windows operating system, you can
restore the factory default settings even if you cannot start the Windows operating system.
Attention: If you restore the hard disk drive from a Rescue and Recovery backup or restore the hard disk
drive to the factory default settings, all files on the primary hard disk drive partition (usually drive C:) will be
deleted in the recovery process. If possible, make copies of important files. If you are unable to start the
Windows operating system, you can use the rescue files feature of the Rescue and Recovery workspace to
copy files from your hard disk drive to other media.

Static electricity prevention
Static electricity, although harmless to you, can seriously damage computer components and options.
Improper handling of static-sensitive parts can cause damage to the part. When you unpack an option or
a CRU, do not open the static-protective package that contains the part until the instructions direct you
to install the part.
When you handle options or CRUs, or perform any work inside the computer, take the following precautions
to avoid static-electricity damage:
• Limit your movement. Movement can cause static electricity to build up around you.
• Always handle components carefully. Handle adapters, memory modules, and other circuit boards by the
edges. Never touch exposed circuitry.
• Prevent others from touching components.
• When you install a static-sensitive option or CRU, touch the static-protective package that contains the
part to a metal expansion-slot cover or other unpainted metal surface on the computer for at least two
seconds. This reduces static electricity in the package and your body.
• When possible, remove the static-sensitive part from the static-protective package and install the part
without setting it down. When this is not possible, place the static-protective package on a smooth,
level surface and place the part on the package.
• Do not place the part on the computer cover or other metal surface.

Usage environment and your health
Integrated wireless cards emit radio frequency electromagnetic energy like other radio devices. However, the
level of energy emitted is far much less than the electromagnetic energy emitted by wireless devices like
for example mobile phones.
Due to the fact that integrated wireless cards operate within the guidelines found in radio frequency safety
standards and recommendations, Lenovo believes they are safe for use by consumers. These standards and
recommendations reflect the consensus of the scientific community and result from deliberations of panels
and committees of scientists who continually review and interpret the extensive research literature.
In some situation or environment, the use of integrated wireless cards might be restricted by the proprietor
of the building or responsible representatives of the organization. These situations and areas might for
example include:
• Using the integrated wireless cards on board of airplanes, in hospitals or near petrol stations, blasting
areas (with electro-explosive devices), medical implants or body-worn electronic medical devices, such
as pace makers.
• In any other environment where the risk of interference to other devices or services is perceived or
identified as harmful.
If you are uncertain of the policy that applies to the use of wireless devices in a specific organization (such as
airport or hospital), you are encouraged to ask for authorization to use integrated wireless cards prior to
turning on the computer.
