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).

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 135 degrees, as this might damage the computer hinge.

your computer properly

Carry

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.

Caring for your computer

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.

care in setting passwords

Take

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.

important tips

Other

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 We b 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.

4 Lenovo 3000 N100 Service and Troubleshooting Guide

Caring for your computer

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.

If you have a problem with your computer, you can test it by using PC-Doctor

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.

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.

Attention

for Windows. To run PC-Doctor for Windows, do as follows:

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 prevent you from accessing this help system.

Error messages

The following is a list of the messages that the BIOS can display. Most of them occur during POST. Some of them display information about a hardware device, e.g., the amount of memory installed. Others may indicate a problem with a device, such as the way it has been configured. Following the list are explanations of the messages and remedies for reported problems. If your system displays one of the messages marked below with an asterisk (*), write down the message and contact your marketing representative. If your system fails after you make changes in the Setup menus, reset the computer, enter Setup and install Setup defaults or correct the error.
