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 39, Appendix B, “Wireless related information” on page 45, Appendix C, “Warranty information” on page 47, and Appendix D, “Notices” on page 61.

DANGER

vTo 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.

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 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.

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

vTo 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.

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

vThe 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.

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

vThe 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.

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

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

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

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 13cm/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.

vWhen picking up your open computer, hold it by the bottom. Do not pick up or hold your computer by the display.

6 ThinkPad® T30 Series Service and Troubleshooting Guide

Caring for your ThinkPad computer

vUse 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

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

vIf 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.

vWait 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.

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. 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

vRemember 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

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 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).

vRegister 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.

vOnly an authorized IBM ThinkPad 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.

Chapter 1. Overview of your new ThinkPad computer 7

Caring for your ThinkPad computer

vTurn off your computer if you are replacing a device in a device bay, or else verify that the device is warm-or hot-swappable.

vIf you exchange drives in your computer, reinstall the plastic bezel faces (if supplied).

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.

Cleaning your computer

Occasionally clean your computer as follows:

vUse a soft cloth moistened with nonalkaline detergent to wipe the exterior of the computer.

vAvoid spraying cleaner directly on the display or the keyboard.

vGently 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.

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 cursor to Programs (in Windows XP, All Programs) and then to

PC-Doctor for Windows.

3.Click PC-Doctor for Windows.

4.Choose either the Run Quick Test Set or the Run Normal Test Set.

Attention

Running the Quick Test Set can take up to 10 minutes or longer. Make sure you have time to run the entire test; do not interrupt the test while it is running.

The Quick Test Set runs many 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 Quick Test Set 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 IBM for support, be sure to print the test log so that you can rapidly provide information to the help technician.

14 ThinkPad® T30 Series Service and Troubleshooting Guide

Solving computer problems

If the screen still remains blank, make sure that:

vThe battery is installed correctly.

vThe ac adapter is connected to the computer and the power cord is plugged into a working electrical outlet.

vThe computer power is on. (Turn on the power switch again for confirmation.)

If these items are properly set, and the screen remains blank, have the computer serviced.

Problem: When I turn on the machine, nothing appears on the screen, but I hear two or more beeps.

Solution: Make sure that the memory card is installed correctly. If it is, but the screen is still blank, and you hear five beeps, have the computer serviced.

If you hear 4 cycles of 4 beeps each, the Security Chip has a problem. Have the computer serviced.

Problem: When I turn on the machine, only a white cursor appears on a blank screen.

Solution: Reinstall your operating system, and turn on the computer. If you still see only the cursor on the screen, have the computer serviced.

Problem: My screen goes blank while the computer is on.

Solution: Your screen saver or power management may be enabled. Move the TrackPoint or press a key to exit the screen saver, or press the power switch to resume from standby or hibernation.

Problem: The DOS full-screen looks smaller.

Solution: If you use a DOS application that supports only 640x480 resolution (VGA mode), the screen image might look slightly distorted or appear smaller than the display size. This is to maintain compatibility with other DOS applications. To expand the screen image to the same size as the actual screen, start the ThinkPad Configuration Program and click LCD; then select the Screen expansion function. (The image might still look slightly distorted.)

Note: If your computer has a screen expansion function, you can use the Fn+F8 keys to expand the screen image.
