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 screen expansion function, you can use the
Fn+F8 keys to expand the screen image.
The system configuration changed between the time your computer entered
hibernation mode and the time it left this mode, and your computer cannot
resume normal operation.
v Restore the system configuration to what it was before your computer
entered hibernation mode.
v If the memory size has been changed, re-create the hibernation file.
