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.

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

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.

vii

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.

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:
• Replace only with a battery of the type recommended by Lenovo.
• Keep the battery pack away from fire.
• Do not expose it to water or rain.
• Do not attempt to disassemble it.
• Do not short-circuit it.
• Keep it away from children.
• Do not drop the battery pack.
Do not put the battery pack in trash that is disposed of in landfills. When disposing of the battery,
comply with local ordinances or regulations.
The battery pack should be stored at room temperature, charged to approximately 30 to 50%
of capacity. We recommend that battery pack be charged about once per year to prevent
overdischarge.

Lithium coin cell battery notice
DANGER
Danger of explosion if battery is incorrectly replaced.
When replacing the lithium coin cell battery, use only the same or an equivalent type that is
recommended by the manufacturer. The battery contains lithium and can explode if not properly
used, handled, or disposed of.
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.

Using the ac power adapter and the battery pack
This topic provides information about how to use the ac power adapter and the battery for your computer.

Checking the battery status
The battery gauge in the Windows notification area displays the percentage of battery power remaining.
The rate at which you use battery power will determine how long you can use the battery between charges.
Because each computer user has different 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: how often you access the hard disk drive, how bright you make the
computer display.

Chapter 2. Using your computer

Using the ac power adapter
The power to run your computer can come either from the lithium-ion battery pack provided with it, or from
ac power through the ac power adapter. While you use ac power, the battery charges automatically.
The ac power adapter has two basic components:
1. The transformer pack that converts ac power for use with the computer.
2. The power cord that plugs into the ac outlet and into the transformer pack.
Attention: Using an improper power cord could cause severe damage to the computer.
Connecting the ac power adapter
To connect the ac power adapter, do the following:
1. Plug the ac power adapter into an electrical outlet.
2. Connect the power cord to the transformer pack.
3. Insert the power jack into the computer.
Tips on using the ac power adapter
When using the ac power adapter, observe the following guidelines:
• 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 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 and the battery
is installed.

Charging the battery
When you find that the battery power is low, you need to charge the battery or replace it with a fully
charged one.
You are recommended to charge the battery in any of the following situations:
• When you purchase a new battery
• If the battery status indicator starts blinking
• If the battery has not been used for a long time
Notes:
• You are advised to install the battery pack when using your computer to prevent small particles from
entering the inside of your computer.
• To maximize the battery life, do not start recharging the battery immediately after it drops from full charge.
• Charge the battery at a temperature between 50 °F and 86 °F (10 °C-30 °C).
• Full charge or discharge is not required.

Maximizing the battery life
To maximize the life of a new battery or a battery that you have not used recently, do either of the following:
• Use the battery until the charge is completely depleted; that is, use the battery until the battery status
indicator starts blinking orange.

User Guide

• Recharge the battery completely before using it. The battery is fully charged if the battery indicator shows
green when the ac power adapter is plugged in.

Handling the battery
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.

DANGER
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:

Chapter 4. You and your computer
This chapter provides information about accessibility and comfort.

Accessibility and comfort
Good ergonomic practice is important to get the most from your personal computer and to avoid discomfort.
Arrange your workplace and the equipment you use to suit your individual needs and the kind of work
that you perform. In addition, use healthy work habits to maximize your performance and comfort while
using your computer.
The following topics provide information about arranging your work area, setting up your computer
equipment, and establishing healthy work habits.
Lenovo is committed to providing the latest information and technology to our customers with disabilities.
Refer to our accessibility information which outlines our efforts in this area.

Ergonomic information
Working in the virtual office might mean adapting to frequent changes in your environment. Following some
simple rules will make things easier and bring you the maximum benefits of your computer. Keeping in mind
such basics as good lighting and proper seating, for example, can help you improve your performance
and achieve greater comfort.
This example shows someone in a conventional setting. Even when not in such a setting, you can follow
many of these tips. Develop good habits, and they will serve you well.

General posture: Make minor modifications in your working posture to deter the onset of discomfort 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 inch). 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 Fn + up/down arrow
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: If available, use chair arm rests or an area on your working surface to provide
weight support for your arms. 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 the 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 Lenovo 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.

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 these important tips, you will get the most use and enjoyment
out of your computer.
Be careful about where and how you work
• Do not eat or smoke over your keyboard. Particles that fall into your keyboard can cause damage.
• 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
(within 13 cm or 5 inch).
• 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 it. 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 palmrest.
• Do not open the display beyond 130 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.
• Before moving your computer, ensure that it is in sleep or hibernation mode, or turned off. This will
prevent damage to the hard disk drive and avoid data loss.
• When picking up your open computer, hold it by the bottom. Do not pick up or hold your computer by
the display.
• Use a quality carrying case that provides adequate cushion and protection. Do not pack your computer in
a tightly packed suitcase or bag.
For outdoor use
• Back up your critical data before you take your computer outdoors.
• Ensure that the battery is fully charged.

User Guide

• Be sure to turn off the power and close the LCD when not in use.
• When you leave the computer in your car, place it on the back seat to avoid being missed.
• Carry the ac power adapter and power cord with the computer.
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.
• When installing the hard disk drives or optical drives, follow the instructions shipped with your hardware,
and apply pressure only where needed on the device.
• Turn off your computer if you are replacing the hard disk drive.
• Store your external and removable hard disk drives or optical drives in the appropriate containers or
packaging when not in use.
• Before you install any of the following devices, touch a metal table or a grounded metal object. This action
reduces any static electricity from your body. The static electricity could damage the device.
– Memory cards, such as SD cards, Memory Stick cards, MultiMediaCard modules, and Memory Stick
Pro cards
– Memory modules
Note: Not all listed devices are included in your computer.
This action reduces any static electricity from your body. The static electricity could damage the device.
• When transferring data to or from a flash media card, such as an SD card, do not put your computer in
sleep or hibernation mode before the data transfer is complete. To do so might cause damage to your
data.
Data protection
• Do not delete unknown files or change the name of files or directories that were not created by you;
otherwise, your computer software might fail to work.
• Be aware that accessing network resources can leave your computer vulnerable to computer viruses,
hackers, spyware, and other malicious activities that might damage your computer, software, or data.
• It is your responsibility to ensure that you have adequate protection in the form of firewalls, antivirus
software, and anti-spyware software and keep the software up to date.
Take care in setting passwords
Remember your passwords. If you forget a supervisor or hard disk password, Lenovo authorized service
providers will not reset it, and you might have to replace your system board or hard disk drive.
Clean the cover of your computer
Occasionally clean your computer by doing the following:
1. Prepare a mixture of a gentle kitchen-use detergent (one that does not contain abrasive powder or
strong chemicals such as acid or alkaline). Use 5 parts water to 1 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.
6. Rinse the sponge with clean running water.

To clean the computer keyboard, do the following:
1. Apply some isopropyl rubbing alcohol to a soft, dust-free cloth.
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 and dust from beneath the keys, you can use a camera blower with a brush
or cool air from a hair drier.
Note: Avoid spraying cleaner directly onto the display or the keyboard.
Cleaning your computer display
To clean your 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 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.
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.

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 may be restricted by the proprietor
of the building or responsible representatives of the organization. These situations and areas may 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.
