2 Lenovo 3000 C100 Service and Troubleshooting Guide
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
v Do not leave the base of your computer 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.
v Place liquids away from your computer to avoid spills, and keep your
computer away from water (to avoid the danger of electrical shock).
v Store packing materials safely out of the reach of children to prevent the
risk of suffocation from plastic bags.
v Keep your computer away from magnets, activated cellular phones,
electrical appliances, or speakers (within 13 cm/5 in).
v Avoid subjecting your computer to extreme temperatures (below 5°C/41°F
or above 35°C/95°F).
Be
gentle with your computer
v Avoid placing any objects (including paper) between the display and the
keyboard or under the keyboard.
v Do not drop, bump, scratch, twist, hit, vibrate, push, or place heavy objects
on your computer, display, or external devices.
v Your computer display 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.
Carry
your computer properly
v Before moving your computer, be sure to remove any media, turn off
attached devices, and disconnect cords and cables.
v Be sure your computer is in standby or hibernation mode, or turned off,
before moving it. This will prevent damage to the hard disk drive and data
loss.
© Copyright Lenovo 2005 3
v When picking up your open computer, hold it by the bottom. Do not pick
up or hold your computer by the display.
v Use a quality carrying case that provides adequate cushion and protection.
Do not pack your computer in a tightly packed suitcase or bag.
Handle storage media and drives properly
v If your computer comes with an optical drive such as CD, DVD, or
CD-RW/DVD drive, do not touch the surface of a disc or the lens on the
tray.
v Wait until you hear the CD or DVD click into the center pivot of an optical
drive such as CD, DVD, or CD-RW/DVD drive before closing the tray.
v When installing your hard disk, diskette, CD, DVD, or CD-RW/DVD drive,
follow the instructions shipped with your hardware, and apply pressure
only where needed on the device.
Take
care in setting passwords
v Remember your passwords. If you forget a supervisor or hard disk
password, Lenovo authorized service provider will not reset it, and you
might have to replace your system board or hard disk drive.
Other
important tips
v 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.
v 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.
v Register your Lenovo products with Lenovo (refer to the Web page:
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.
v Only an authorized Lenovo notebook repair technician should disassemble
and repair your computer.
v Do not modify or tape the latches to keep the display open or closed.
v Take care not to turn your computer over while the ac adapter is plugged
in. This could break the adapter plug.
v Store your external and removable hard disk, diskette, CD, DVD, and
CD-RW/DVD drives in the appropriate containers or packaging when they
are not being used.
Caring for your computer
4 Lenovo 3000 C100 Service and Troubleshooting Guide
v 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.
– PC Card
– Smart Card
– Memory Card, such as SD Card, Memory Stick, and MultiMedia Card
– Memory module
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.
Note: Avoid spraying cleaner directly on the display or the keyboard.
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.
Caring for your computer
Chapter 2. Caring for your computer 5
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.

Diagnosing problems
If you have a problem with your computer, you can test it by using
PC-Doctor
®
for Windows. To run PC-Doctor for Windows, do as follows:
1. Click Start.
2. Move the pointer to All Programs and then to PC-Doctor for Windows.
3. Click PC-Doctor.
4. Choose one of the tests from either Device Categories or Test Scripts.
Attention
Running any tests may take up to several minutes or longer. Make sure
you have time to run the entire test; do not interrupt the test while it is
running.
The System Test of the Test Scripts runs some tests of critical hardware
components, but it does not run all of the diagnostic tests in PC-Doctor for
Windows. If PC-Doctor for Windows reports that all of the tests in the System
Test have been run and that it has found no problems, consider running more
of the tests in PC-Doctor for Windows.
If you are preparing to contact the Customer Support Center, be sure to print
the test log so that you can rapidly provide information to the help technician.
Troubleshooting
If you do not find your problem here, refer to Access Help, your on-board
help system. The following section only describes problems that might

confirmation.)
If these items are properly set, and the screen remains blank, have the
