Solution: First, reboot your system by pressing Ctrl+Alt+Del. If that does not
work, hold down the power switch for more than 4 seconds. If this does not
resolve the problem, you may need to reinstall your operating system.
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 might 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.

canceled.
