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.
© Copyright Lenovo 2007
When the AC 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 adapter to warm
your body. Extended contact with your body,
even through clothing, may cause a skin
burn.

Route the cables of an AC adapter, a mouse, a
keyboard, a printer, or any other electronic
device, or communication lines, 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 disturb
the operation of your computer. Applying
strong force to the cables may damage or
break them.
Before moving your computer, do one of the
following: turn it off or press Fn + F1 to put it
in sleep mode or hibernation mode.
Before moving the computer, make sure that
the power on indicator is off. This will help to
prevent damage to the hard disk drive, and
possible loss of data.

Chapter 2. Caring for Your Computer
Though 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.
Important Tips
Be Careful about Where and How You Work
• Do not leave the base of your computer, or any other part that becomes
hot during operation, in contact with your lap or any part of your body
for an extended period when the computer is functioning or when the
battery is charging. Your computer dissipates some heat during normal
operation. This heat is a function of the level of system activity and
battery charge level. Extended contact with your body, even through
clothing, could cause discomfort or, eventually, a skin burn.
• When the AC 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 adapter to warm
your body. Extended contact with your body, even through clothing,
may cause a skin burn.
• Route the cables of an AC adapter, a mouse, a keyboard, a printer, or any
other electronic device, or communication lines, 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 disturb the operation of
your computer. Applying strong force to the cables may damage or
break them.
• Place liquids away from your computer to avoid spills, and keep your
computer away from water (to avoid the danger of electrical shock).
• 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 in).
• Avoid subjecting your computer to extreme temperatures (below 5°C/
41°F or above 35°C/95°F).

Lenovo EVEREST UG.book Page 4 Friday, August 17, 2007 5:40 PM
Caring for Your Computer
• 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
may become electrostatically charged. Such a charge may 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 under the keyboard.
• Do not drop, bump, scratch, twist, hit, vibrate, push, or place heavy
objects on your computer, display, or external devices.
Carry Your Computer Properly
• Before moving your computer, be sure to remove any media, turn off
attached devices, and disconnect cords and cables.
• Be sure your computer is in sleep or hibernation mode, or turned off,
before moving it. This will prevent damage to the hard disk drive and
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.

Lenovo EVEREST UG.book Page 5 Friday, August 17, 2007 5:40 PM
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 an
optical drive before closing the tray.
• When installing your hard disk, follow the instructions shipped with
your hardware, and apply pressure only where needed on the device.
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.
Other Important Tips
• Your computer modem might use only an analog telephone network, or
public-switched telephone network (PSTN). Do not connect the modem
to a PBX (private branch exchange) or any other digital telephone
extension line because this could damage your modem. Analog phone
lines are often used in homes, while digital phone lines are often used in
hotels or office buildings. If you are not sure which kind of phone line
you are using, contact your telephone company.
• Your computer might have both an Ethernet connector and a modem
connector. If so, be sure to connect your communication cable to the
correct one, so your connector is not damaged.
• Register your Lenovo products with Lenovo (refer to the Web page:
http://www.lenovo.com/register). This can help authorities return your
computer to you if it is lost or stolen. Registering your computer also
enables Lenovo to notify you about possible technical information and
upgrades.
• Only an authorized Lenovo repair technician should disassemble and
repair your computer.
• Do not modify or tape the latches to keep the display open or closed.
• Take care not to turn your computer over while the AC adapter is
plugged in. This could break the adapter plug.
• Turn off your computer if you are replacing a device, or else verify that
the device is warm- or hot-swappable.

Lenovo EVEREST UG.book Page 6 Friday, August 17, 2007 5:40 PM
Caring for Your Computer
• 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.
– ExpressCard
– Memory Card, such as SD Card, Memory Stick, MultiMediaCard,
xD-Picture Card, and Memory Stick Pro card.
–Memory module
– PCI Express Card
• 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.
Cleaning the Cover of Your Computer
Occasionally clean your computer as follows:
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.
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 cloth fibers from
the computer surface.
Cleaning Your Computer Keyboard
1. Absorb some isopropyl rubbing alcohol on 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 may 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.

Lenovo EVEREST UG.book Page 7 Friday, August 17, 2007 5:40 PM
Cleaning Your Computer Display
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.

Accessibility and Comfort
Because your computer enables you to work in so many places, it is
important that you remain attentive to good posture, good lighting, and
proper seating. By keeping these considerations in mind, you can improve
performance and achieve greater comfort. Lenovo is committed to
providing the latest information and technology to our customers with
disabilities.
Ergonomic Information
Working in the virtual office may 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.
Note: This example shows someone in a conventional setting. Even if you
work in a casual, less conventional setting, many of the tips in this
section still apply. Develop good habits, and they will serve you well.

General Posture: Below are some general recommendations for assuming a
healthy working posture. It is best to periodically 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 will also help to prevent any minor discomfort
associated with your working posture.
Display: Position the display to maintain a comfortable viewing distance of
510-760 mm (20-30 in). 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 key 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, utilize 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 may 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?
Your computer’s visual display screen is 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.
