Page 10
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.
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.

Power management
Use your computer with ac power whenever ac power is available. Use your computer with battery power
when ac power is not available.
Checking the battery status
The battery icon in the Windows notification area displays the percentage of battery power remaining.
Different computer components consume power at different rates. The more you use the power-intensive
components, the faster you consume battery power. 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?
Using the ac power adapter
When 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 could cause severe damage to the computer.
Connecting the ac power adapter
To connect the ac power adapter, do the following:
1. Plug the power cord into an electrical outlet.
2. Connect the power cord to the transformer pack.
3. Connect the ac power adapter to the ac power connector of the computer.
Tips on using the ac power adapter
Observe the following guidelines when 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 and the battery is
installed. Charge it in any of the following conditions:
– When you purchase a new battery
– If the battery meter at the bottom of your display indicates a low batter charge level
– If the battery has not been used for a long time
Chapter 2. Using your computer 15

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
CRU, do not open the static-protective package containing the part until the instructions direct you to install
it.
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 containing 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 packaging and install the part
without setting it down. When this is not possible, place the static-protective packaging on a smooth, level
surface and place the part on it.
• Do not place the part on the computer cover or other metal surface.

An important part of owning a Lenovo notebook computer is maintenance. With proper care, you can avoid
common problems. The chapter provides information that can help you keep your computer running
smoothly.
• “General tips for preventing problems” on page 39
• “Taking care of your computer” on page 39
General tips for preventing problems
This topic provides general tips for you to prevent problems when using your computer.
1. Check the capacity of your hard disk drive from time to time. If the hard disk drive gets full, the
operating system will slow down and might produce errors.
2. Empty your recycle bin on a regular basis.
3. To free up disk space, uninstall unused programs.
4. Clean out your Inbox, Sent, and Trash folders from your e-mail client program.
5. Back up your data at least once a week. If critical data is present, it is recommended that you perform a
daily backup operation. Lenovo has many backup options available for your computer. CD-RW drives
and CD-RW/DVD drives are available for most computers and can be installed easily.
6. Schedule system restore operations to take a system snapshot periodically.
Note: Always take a system snapshot before installing new drivers, updating software, or installing
new software.
7. Update device drivers and BIOS when needed.
8. Profile your machine at http://www.lenovo.com/support to keep up to date with current drivers and
revisions.
9. Keep up to date for device drivers on other non-Lenovo hardware. You might want to read the device
driver information release notes before updating for compatibility or known issues.
10. 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.
11. If required, you can find your country's Customer Support Center at http://www.lenovo.com/support.
Note: When calling the Customer Support Center, ensure 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 message written down.
12. If you want to get the latest software source for Microsoft

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 the computer more than 13 cm (5 inches) away from magnets, activated cellular phones, electrical
appliances, or speakers.
• 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, 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, increases the risk of ESD. Therefore, when using the computer close to
an appliance that produces negative ions, give special attention to the following:
• Avoid directly exposing your computer to the air from an appliance that produces 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.
• 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 prevents
damage to the hard disk drive and avoids 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.
• 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 insolated.
• 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.
40 User Guide
Page 55
• 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, MultiMediaCards, and Memory Stick Pro cards
–Memory modules
Note: Not all devices listed are included in your computer.
• 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. Otherwise, data might be damaged.
Clean the computer cover
Occasionally clean your computer cover 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 cover to remove the detergent.
6. Rinse the sponge with clean running water.
7. Wipe the cover with the clean sponge.
8. Wipe the cover again with a dry, soft, lint-free cloth.
9. Wait for the cover to dry completely and remove any fibers from the cloth.
Note: Before cleaning the computer cover, ensure that you have turned off the computer and disconnected
the power cord.
Clean the computer keyboard
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. Ensure that no liquid drips onto or
between the keys.
3. Allow the keyboard to dry.
4. To remove any crumbs and dust from beneath the keys, 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.
Clean the 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 the 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.
Chapter 7. Preventing problems 41

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.
Appendix A. Regulatory information 49
Page 64
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.
