Important safety information
Note: Read the important safety information first.
Read this 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 Limited Warranty. For more information, see "Warranty Information" in the Safety, Warranty, and Setup

ThinkPad S5 2nd Generation 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.
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
product are zero. Before you remove the covers from a product equipped with a power cord, always make
© Copyright Lenovo 2017
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 you open the computer cover, turn off the computer and wait several minutes until the
computer is cool.
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 H03VV-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.
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.
vi
ThinkPad S5 2nd Generation 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.

Using the battery
When you 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 are 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 every computer user has individual habits and needs, it is difficult to predict how
long a battery charge lasts. 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:
– How often you access the storage drive
– How bright you make the computer display

operation.
Cleaning the computer cover: Wipe it with a lint-free cloth dampened in mild soap and water. Avoid
applying liquids directly to the cover.
Cleaning the keyboard: Wipe the keys one by one with a lint-free cloth dampened in mild soap and water.
If you wipe several keys at a time, the cloth might hook onto an adjacent key and possibly damage it. Avoid
spraying cleaner directly onto the keyboard. To remove any crumbs or dust from beneath the keys, you can
use a camera blower with a brush or use cool air from a hair dryer.
Cleaning the computer screen: Scratches, oil, dust, chemicals, and ultraviolet light can affect the
performance of your computer screen. Use a dry, soft lint-free cloth to wipe the screen gently. If you see a
scratchlike mark on your screen, it might be a stain. Wipe or dust the stain gently with a soft, dry cloth. If the
stain remains, moisten a soft, lint-free cloth with water or eyeglass cleaner, but do not apply liquids directly
to your computer screen. Ensure that the computer screen is dry before closing it.

Chapter 5. Security
This chapter provides information about how to protect your computer from unauthorized use.
Using passwords
You can help prevent your computer from unauthorized use by using passwords. After you set a password, a
prompt is displayed on the screen each time you turn on the computer. Enter your password at the prompt.
You cannot use the computer unless you type the correct password.
If you have set a power-on password, a supervisor password, or a hard disk password, it unlocks
automatically when the computer resumes from sleep mode.
Note: If a Windows password has been set, you are prompted to enter it when the computer resumes
from sleep mode.
Passwords introduction
Power-on password
You can set a power-on password to help protect your computer against unauthorized access.
If you set a power-on password, the password prompt is displayed on the screen whenever you turn on the
computer. You must enter the correct password to start using the computer.
When this icon is displayed, type a power-on password or a supervisor password.
Supervisor password
The supervisor password protects the system information stored in the ThinkPad Setup program. If you have
set a supervisor password, no one can change the configuration of the computer without the password. It
provides the following security features:
• If only a supervisor password is set, a password prompt is displayed when you try to start the ThinkPad
Setup program. Unauthorized users cannot access the ThinkPad Setup program without the password.
• The system administrator can use the supervisor password to access a computer even if the user of that
computer has set a power-on password. The supervisor password overrides the power-on password.
• The system administrator can set the same supervisor password on many ThinkPad notebook computers
to make administration easier.
Hard disk passwords
Setting a hard disk password prevents unauthorized access to the data on the hard disk drive. When
a hard disk password is set, you are prompted to type a valid password each time you try to access the
hard disk drive.
The following two types of hard disk passwords can help protect the information stored on the storage drive:
• User hard disk password
If a user hard disk password has been set, but no master hard disk password has been, the user must
enter the user hard disk password to access files and applications on the storage drive.
• Master hard disk password
© Copyright Lenovo 2017

The master hard disk password also requires a user hard disk password. The master hard disk password
is set and used by a system administrator. It enables the administrator to access any storage drive in
a system like a master key. The administrator sets the master password; then assign a user password
for each computer in the network. The user can then change the user password as desired, but the
administrator still can get access by using the master password.
When a master hard disk password is set, only the administrator can remove the user hard disk password.
When this icon is displayed, type a user hard disk password. To type a master hard disk password,
press F1. When the icon changes to
, type the master hard disk password. To return to the icon
, press F1 again.
Tips on using the hard disk passwords:
• You can set the minimum length of a hard disk password.
• If you set a hard disk password of over seven characters, the storage drive can be used only with a
computer that can recognize a hard disk password of over seven characters. If you then install the
storage drive in a computer that cannot recognize a hard disk password that contains more than seven
characters, you cannot access the drive.
• Record your password and store it in a safe place. If you forget the user hard disk password, or both user
and master hard disk passwords, Lenovo cannot reset your passwords or recover data from the storage
drive. You must take your computer to a Lenovo reseller or a marketing representative to have the storage
drive replaced. Proof of purchase is required, and a fee will be charged for parts and service.
Notes: The eDrive storage drives or Trusted Computing Group (TCG) Opal-compliant storage drives provide
self-encryption capabilities to secure your data.
• If a TCG Opal-compliant storage drive and a TCG Opal management software program are installed, and
the TCG Opal management software program is activated, the hard disk password is not available.
• If an eDrive storage drive is installed in your computer, and your computer is preinstalled with the
Windows 10 operating system, the hard disk password is not available.
Setting, changing, or removing a password
Before you start, print these instructions.
To set, change, or remove a password, do the following:
1. Restart the computer. When the logo screen is displayed, press F1 to start the ThinkPad Setup program.
2. Select Security ➙ Password by using the directional keys.
3. Depending on the password type, select Power-on Password, Supervisor Password, or Hard disk x
Password.
4. Follow the instructions on the screen to set, change, or remove a password.
You might want to record your password and store it in a safe place. Otherwise, if you forget the password,
you have to take your computer to a Lenovo reseller or a marketing representative to have the password
canceled.
Hard disk security
To protect the computer from unauthorized security attacks, refer to the following tips to enhance security:
40
ThinkPad S5 2nd Generation User Guide
• Set a power-on password as well as a hard disk password. For security, a longer password is
recommended.
• The hard disk drive built into your computer can be protected by UEFI BIOS. To provide reliable security,
use the security chip and a security program with the Trusted Platform Module (TPM) management
feature. See “Setting the security chip” on page 41.
• If a Disk Encryption storage drive is installed in your computer, ensure to protect the contents of your
computer from unauthorized access by use of drive encryption software, such as Microsoft Windows
BitLocker® Drive Encryption.
• Before you dispose of, sell, or hand over your computer, delete the data stored on it. For more information,
see “Deleting data from your storage drive” on page 42.
Using Windows BitLocker Drive Encryption
To help protect your computer against unauthorized access, use the drive encryption software, such as
Windows BitLocker Drive Encryption.
Windows BitLocker Drive Encryption (referred to as BitLocker) is an integral security feature of some editions
of the Windows operating system. It can help you protect the operating system and data stored on your
computer, even if your computer is lost or stolen. BitLocker can encrypt all user and system files, including
the swap and hibernation files.
BitLocker uses the TPM to provide enhanced protection for your data and to ensure early boot component
integrity. A compatible TPM is defined as a V2.0 TPM.
To check the BitLocker status, go to Control Panel, view Control Panel by Category, and click System and
Security ➙ BitLocker Drive Encryption.
For more information, see the help system of the Windows operating system, or search for “Microsoft
Windows BitLocker Drive Encryption Step-by-Step Guide” on the Microsoft Web site.
Disk Encryption hard disk drive and Encryption solid-state drive
Some models contain the Disk Encryption hard disk drive or Encryption solid-state drive. This encryption
technology helps to protect your computer against security attacks on media, NAND flash, or device
controllers by use of a hardware encryption chip. For the efficient use of the encryption feature, set a
hard disk password for the internal storage drive.
Setting the security chip
Strict security requirements are imposed on network client computers that transfer confidential information
electronically. Depending on the options you ordered, your computer might have an embedded security chip
(a cryptographic microprocessor). With the security chip, you can do the following:
• Protect your data and system
• Strengthen access controls
• Secure communications
Before you start, print these instructions.
To set an item on the Security Chip submenu, do the following:
1. Restart the computer. When the logo screen is displayed, press F1 to start the ThinkPad Setup program.
2. Select Security ➙ Security Chip by using the directional keys.
3. Press Enter. The Security Chip submenu opens.
Chapter 5. Security
41
4. Move to an item you want to set by using the directional keys. When the item is highlighted, press Enter.
5. Set other items that you want to set.
6. Press F10. A Setup Confirmation window is displayed. Select Yes to save the configuration changes
and exit.
Notes:
• Ensure that the supervisor password has been set in ThinkPad Setup. Otherwise anyone can change the
settings for the security chip.
• When you clear the security chip, turn off your computer and then turn it on again after you set the
security chip to Active. Otherwise, the Clear Security Chip option is not displayed.
Deleting data from your storage drive
Some of the data stored on the storage drive might be sensitive. Handing your computer over to someone
else without deleting the installed software, such as operating systems and programs, might even violate
the license agreements. Be sure to delete data stored on the storage drive before you dispose of, sell,
or hand over your computer.
You can use the following methods to delete data from the storage drive:
• Move the data to the Recycle Bin, and then empty the Recycle Bin.
• Format your storage drive, using the software to initialize it.
• Use the recovery program provided by Lenovo to bring the storage 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. 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 storage 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.
Some computers might support the Disk Encryption hard disk drive or Encryption solid-state drive and have
such a drive installed. You can logically dispose of all the data on the drive in a short time by erasing the
cryptographic 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 access, intrusions, and Internet attacks. It also protects your privacy.
For more information about how to use the firewall program, see the help system that comes with the
program.

Installing device drivers
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 component, the operating system must 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 properly if corruption occurs.
It is not always necessary to download the latest drivers. However, you should download the latest driver for
a component when you notice poor performance from that component or when you added a component.
This action 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 Support Web site by doing the
following:
1. Go to http://www.lenovo.com/support.
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 Lenovo Companion
The system update function of Lenovo Companion 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 Lenovo Companion connects to the Lenovo Support Web site, the program automatically
recognizes the following information and determines what updates are available for your computer:
• Machine type and model of your computer
• Installed operating system
• Language of the operating system
Lenovo Companion 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, Lenovo Companion
automatically downloads and installs the updates.
Lenovo Companion 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 scheduled
updates to search by the critical severity level so the list you choose from contains only those update
types that you need.
For more information about how to use Lenovo Companion, see the help system of the program.
Using the ThinkPad Setup program
The ThinkPad Setup program enables you to select the preferred settings for your computer through
configuring the BIOS.

Using system management
This topic is primarily intended for the 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 storage 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 2.8 or later. 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.
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.
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.
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
Note: If a supervisor password has been set, you are 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. Restart the computer. When the logo screen is displayed, press F1 to start the ThinkPad Setup program.
2. Select Config ➙ Network. The Network submenu is displayed.
3. Select a corresponding option for the Wake on LAN feature.
4. Press Fn+F10 to save the settings and exit.
Defining a Network Boot sequence
When the computer wakes on LAN, the computer boots 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. Restart the computer. When the logo screen is displayed, press F1 to start the ThinkPad Setup program.
2. Select Startup ➙ Network Boot. The boot device list is displayed.
3. Select a boot device to make it as the top boot priority.

• Problem: I cannot move the volume slider or balance slider.
Solution: The slider might be grayed out. This means that its position is fixed by the hardware and
cannot be changed.
• Problem: The volume sliders do not stay in place when some audio programs are used.
Solution: It is normal for the sliders to change position when certain sound programs are used. The
programs are aware of the settings in the Volume Mixer window and are enabled to change the settings
themselves. An example is the Windows Media Player program. Usually the program has sliders available
to control the sound from within the program.
• Problem: The balance slider cannot completely mute one channel.
Solution: The control is designed to compensate for minor differences in balance and does not
completely mute either channel.
• Problem: There is no volume control for MIDI sound in the Volume Mixer window.
Solution: Use the hardware volume control. This is because the built-in synthesizer software does
not support the control.
• Problem: The sound cannot be turned off even if I set the Master volume control at minimum.
Solution: You still can hear some sound even though you have set the Master volume control at minimum.
To turn off the sound completely, go to the Master volume control and select Mute speakers.
• Problem: When I connect headphones to my computer while playing sound, a speaker does not
produce sound.
Solution: When the headphones are attached, the streaming is automatically redirected to it. If you want
to listen to sound from the speakers again, ensure that you set those speakers as the default device. For
more information, see the help information system for Realtek HD Audio Manager.
• Problem: Sound does not come from a headphone or a speaker, or the computer cannot record sounds.
Solution: To switch from one device to another (for example, from a speaker to a headphone, or from
an external microphone to a built-in microphone), do the following:
1. Go to Control Panel, and ensure that you view Control Panel by Category.
2. Click Hardware and Sound.
3. Click the SmartAudio icon.
4. Ensure that the computer is in MULTI-STREAM mode in the Device advanced settings window.
5. In the Volume Mixer window, select the device you want, for example, speakers.
6. Play any sound through a music program (for example, Windows Media Player). Ensure that sound
comes from the speakers now.
7. Then, if you would like to switch to a headphone, close the music program.
8. Go to the Volume Mixer window. Then select another device (for example, the headphone).
9. Play any sound through the music program. Ensure that sound comes from the headphone attached
directly to the system. For more information, see the help information system of the SmartAudio
program.
Note: The Volume Mixer window of SmartAudio displays all audio devices detected in the system,
such as speakers for a playback device, or a built-in microphone for a recording device. A check
mark beside the audio device shows that the device has been selected.
