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.

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. This function is not supported

in Windows

XP and Windows

2000.

A password problem

Problem: I forgot my password.

Solution: If you forgot your power-on password, you must take your

computer to an IBM reseller or marketing representative to have the password

canceled.

If you forgot 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.

If you forgot 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.
