Problem:
My screen goes blank while the computer is on.
Solution
Your screen saver or power management may be enabled. Touch the
TrackPoint pointing device or the touch pad, or press a key to exit the
screen saver, or press the power switch to resume from standby or

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.)
