Note

Before using this information and the product it supports, be sure to read the general information under Appendix A, “Important safety instructions” on page 47, Appendix B, “Warranty Information” on page 51, Appendix C, “Notices” on page 65, and Appendix D, “Wireless Regulatory Information” on page 75.

DANGER

v To avoid electric shock hazard, connect and disconnect cables appropriately when installing, moving or opening

the covers of this product or attached devices. Use the power cord with a properly grounded outlet.

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 To reduce the risk of electric shock, do not use your computer in or near water.

v To avoid electric shock, do not use your computer with the telephone cable connection during an electrical

storm. Do not connect the cable to or disconnect it from the telephone outlet on the wall during an electrical storm.

v Store packing materials safely out of the reach of children to prevent the risk of suffocation from plastic bags.

v The battery pack contains a small amount of harmful substances. There is danger of an explosion if the battery

pack is incorrectly replaced, exposed to fire or water, short-circuited or disassembled. Keep the battery pack away from children and do not put it in trash that is disposed of in landfills.

v To reduce the risk of fire, use only No. 26 AWG or thicker telephone cable.

v The fluorescent lamp in the LCD contains mercury. Do not put it in trash that is disposed of in landfills. Rough

handling or dropping the computer can cause the LCD to break and the internal fluid to get into your eyes or on your hands. Immediately wash the affected areas with water. If symptoms persist, seek medical care.

v Do not disassemble the optical storage drive unit, as this might result in hazardous radiation exposure.

v Avoid direct eye exposure with the laser beam contained in some drives.

ThinkPad®R30 Series Service and Troubleshooting Guide

Caring for your ThinkPad computer

Though your computer is designed to function reliably in normal work environments, you need to use common sense when 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).

Caring for your ThinkPad computer

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 about 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.

Chapter 1. Overview of your new ThinkPad computer 7

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 If your computer comes with a diskette drive, avoid inserting diskettes at

an angle and attaching multiple or loose diskette labels, as these can lodge in the drive.

v Do not touch the surface of a CD or DVD, or the lens on the CD or DVD

tray.

v Wait until you hear the CD or DVD click into the center pivot of the CD or

DVD drive before closing the CD or DVD tray.

v If your computer comes with a CD-RW or DVD/CD-RW drive, make sure

your computer is protected from vibration when writing CDs. Vibration may result in errors or damaged CDs. Even typing on the computer will cause vibration.

v Do not get fingerprints, dust, or smudges on the recording/reading side of

the CD-R or CD-RW disc. Do not use it for recording even if you cleaned it with disc cleaning liquid and cloth. The disc can be used for reading if you clean it.

v When installing your hard disk, CD or DVD drive, or installing an external

diskette 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 your power-on password, you

have to take your computer to an IBM reseller or marketing representative to have the password canceled.

Attention: If you forget your hard disk password, IBM will not reset your password or recover data from the hard disk. You must take your computer to an IBM reseller or an IBM marketing representative to have the hard disk drive replaced. Proof of purchase is required, and a fee will be charged for parts and service.

Attention: You might want to note your password and keep it in a safe place. If you forget your supervisor password, IBM will not reset your password. You must take your computer to an IBM reseller or IBM marketing representative to have the system board replaced. Proof of purchase is required, and a fee will be charged for parts and service.

Other important tips

v Your computer modem may use only an analog telephone network, or

public-switched telephone network (PSTN). Do not connect the modem to a

ThinkPad®R30 Series Service and Troubleshooting Guide

Caring for your ThinkPad computer

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.pc.ibm.com/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.

v Turn off your computer if you are replacing a device in a device bay. 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 and 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 dry, soft cloth.
