Solving computer problems

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 pointer appears on a blank screen.

Solution:

Reinstall your operating system, and turn on the computer. If you still see only the pointer 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. Touch the TrackPoint or press a key to exit the screen saver, or press the power switch to resume from standby or hibernation mode.

Problem:

The DOS full-screen looks smaller.

Solution:

If you use a DOS application that supports only 640×480 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.)

A password problem

Problem:

I forgot my password.

Solution:

If you forgot your power-on password, you must take your computer to a Lenovo authorized servicer or a marketing representative to have the password canceled.

If you forgot your hard disk password, a Lenovo authorized servicer can not reset your password or recover data from the hard disk. You must take your computer to a Lenovo authorized servicer or a marketing representative to have the hard disk drive replaced. Proof of purchase is required, and a fee will be charged for parts and service.
