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.

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

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.

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).

Chapter 1. Overview of your new ThinkPad computer 5

Caring for your ThinkPad computer

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 135 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.

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

vIf 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.

vIf your computer comes with a CD or DVD drive, do not touch the surface of a CD or the lens on the CD or DVD tray.

vWait 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.

vWhen installing your hard disk, diskette, CD, or 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

6 ThinkPad® X Series Service and Troubleshooting Guide

Caring for your ThinkPad computer

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.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.

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.

vTurn off your computer if you are replacing a device in a device bay, or else verify that the device is warmor 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, and 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 dry, soft cloth.

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 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.

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.

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.

A password problem

Problem: I forgot my password.

Solution: 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.

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.

TrackPoint problems

Problem: The cursor drifts when the computer is turned on or after it resumes normal operation.

Solution: The cursor might drift when you are not using the TrackPoint during normal operation. This is a normal characteristic of the TrackPoint and is not a defect. Cursor drifting might occur for several seconds under the following conditions:

vWhen the computer is turned on.

vWhen the computer resumes normal operation.

vWhen the TrackPoint is pressed for a long time.

vWhen the temperature changes.

Problem: The cursor does not work for a while after the settings in the Mouse Properties window have been changed.

Solution: This is a normal characteristic of the cursor. Wait several seconds until the cursor returns to the normal state.

Problem: The mouse or pointing device does not work.

Solution: Make sure that the TrackPoint is enabled in the ThinkPad Configuration Program, and then try using the TrackPoint. If the TrackPoint works, the error might be due to the mouse.

Make sure that the mouse or pointing-device cable is securely connected to the computer.

If your mouse is incompatible with the IBM® PS/2® mouse, disable the TrackPoint, using the ThinkPad Configuration Program.

Standby or hibernation problems

Problem: The computer returns from standby mode unexpectedly by disconnecting a device from the USB connector or carring your computer with a USB device (especially a USB mouse) connected.

Solution: Your computer is enabled to return from standby mode when detecting any activity on a device attached to the USB connector. Make sure to disconnect a device from the USB connector in advance or disable this function to prevent this problem.

Problem: The computer enters standby mode automatically.

Solution: If the processor reaches a temperature that is too high, the computer automatically enters standby mode to allow the computer to cool and to protect the processor and other internal components.

Problem: The computer enters standby mode immediately after Power-On Selftest (POST) (the standby indicator light turns on).

Solution: Make sure that:

vThe battery is charged.

vThe operating temperature is within the acceptable range. Refer to “Specifications” in this Guide.

If these items are correct, have the computer serviced.

Problem: The critical low-battery error message is displayed, and the computer immediately turns off.

Chapter 2. Solving computer problems 19

Solving computer problems

Solution: The battery power is getting low. Connect the ac adapter to the computer, or replace the battery with a fully charged one.

Problem: When you take action to return from standby mode, the computer display remains blank.

Solution: Check whether an external monitor was disconnected while the computer was in standby mode. Do not disconnect the external monitor while the computer is in standby mode or hibernation mode. If no external monitor is attached when the computer resumes, the computer display remains blank and output is not displayed. This restriction does not depend on the resolution value. Press Fn+F7 to bring up the computer display.

Problem: The computer does not return from standby mode, or the standby indicator stays on and the computer does not work.

Solution: The computer automatically enters standby or hibernation mode when the battery is depleted. Connect the ac adapter to the computer; then press Fn.

Problem: Your computer does not enter standby or hibernation mode.

Solution: Check whether any option has been selected that would disable your computer from entering standby or hibernation mode.

Problem: The computer does not enter standby mode as set by the timer under Windows 98 or Windows NT®.

Solution:

For Windows 98:

The generic CD-ROM or DVD-ROM driver for Windows 98 accesses the internal CD-ROM or DVD-ROM drive every 3 seconds to see whether a CD-ROM is inserted there. This prevents your computer from entering standby mode even after a timeout. To enable the computer to enter standby mode, do the following:

1.Click Start.

2.Move the cursor to Settings and Control Panel.

3.Click Control Panel, and then double-click System.

4.Click the Device Manager tab.

5.Click the + mark of CD-ROM.

6.Double-click the name of the CD-ROM or DVD-ROM.

7.Click the Settings tab.
