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
vDo 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 afunction of the level of system activity and
battery charge level. Extended contact with your body, even through
clothing, could cause discomfort or, eventually, askin burn.
vPlace liquids away from your computer to avoid spills, and keep your
computer away from water (to avoid the danger of electrical shock).
vStore packing materials safely out of the reach of children to prevent the
risk of suffocation from plastic bags.
vKeep your computer away from magnets, activated cellular phones,
electrical appliances, or speakers (within 13 cm/5 in).
vAvoid subjecting your computer to extreme temperatures (below 5°C/41°F
or above 35°C/95°F).
Be gentle with your computer
vAvoid placing any objects (including paper) between the display and the
keyboard or under the keyboard.
vDo not drop, bump, scratch, twist, hit, vibrate, push, or place heavy objects
on your computer, display, or external devices.
vYour 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
vBefore moving your computer, be sure to remove any media, turn off
attached devices, and disconnect cords and cables.
vBe 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

vWhen picking up your open computer, hold it by the bottom. Do not pick
up or hold your computer by the display.
vUse aquality carrying case that provides adequate cushion and protection.
Do not pack your computer in atightly packed suitcase or bag.
Handle storage media and drives properly
vIf your computer comes with an optical drive such as CD, DVD, or
CD-RW/DVD drive, do not touch the surface of adisc or the lens on the
tray.
vWait 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.
vWhen 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
vRemember your passwords. If you forget asupervisor 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
vYour 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.
vYour computer might have both an Ethernet connector and amodem
connector. If so, be sure to connect your communication cable to the correct
one, so your connector is not damaged.
vRegister 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.
vOnly an authorized Lenovo notebook repair technician should disassemble
and repair your computer.
vDo not modify or tape the latches to keep the display open or closed.
vTake care not to turn your computer over while the ac adapter is plugged
in. This could break the adapter plug.
vStore 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.

Diagnosing problems
If you have aproblem 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

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.
