Chapter 1. Overview of your new ThinkPad computer 5

Caring for your ThinkPad 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 13cm/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.

v When picking up your open computer, hold it by the bottom. Do not pick

up or hold your computer by the display.

ThinkPad®T30 Series Service and Troubleshooting Guide

Caring for your ThinkPad computer

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 Avoid inserting diskettes at an angle and attaching multiple or loose

diskette labels, as these can lodge in the drive.

v If your computer comes with a 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 the 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. See Access ThinkPad, your on-board help system, for information on replacing your hard disk drive (open Access ThinkPad by pressing the ThinkPad button.).

Take care in setting passwords

v Remember your passwords. If you forget a supervisor or hard disk

password, IBM 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. See Access ThinkPad, your on-board help system, for information on the location of these connectors (press the ThinkPad button to open Access ThinkPad).

v Register your ThinkPad products with IBM (refer to the Web page:

www.ibm.com/pc/register). This can help authorities return your computer to you if it is lost or stolen. Registering your computer also enables IBM to notify you about possible technical information and upgrades.

v Only an authorized IBM ThinkPad 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.

Chapter 1. Overview of your new ThinkPad computer 7

Caring for your ThinkPad computer

v Turn off your computer if you are replacing a device in a device bay, or else

verify that the device is warm-or hot-swappable.

v If you exchange drives in your computer, reinstall the plastic bezel faces (if

supplied).

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.

Cleaning your computer

Occasionally clean your computer as follows:

v Use a soft cloth moistened with nonalkaline detergent to wipe the exterior

of the computer.

v Avoid spraying cleaner directly on the display or the keyboard.

v Gently wipe the display with a soft, dry cloth. If you see a scratchlike mark

on your display, it might be a stain transferred from the keyboard or the TrackPoint pointer when the cover was pressed from the outside. Wipe or dust the stain gently with a soft, dry cloth. If the stain remains, moisten a soft, lint-free cloth with water that does not contain impurities, wring out as much of the water as you can, and then wipe the display again. Be sure to dry the display before closing it.
