The DOS full-screen looks smaller.
640 x 480
If you use a DOS application that supports only the 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 look slightly distorted.)
Note: You can use the Fn+F8 keys to do the same thing if your com-
puter has screen image.
Hibernation error The system configuration differs between the time your computer
entered hibernation mode and the time it exited this mode, and your
computer cannot resume normal operation.
Ÿ
Restore the system configuration to what it was before your com-
puter entered hibernation mode.
Ÿ
If the memory size was changed, re-create the hibernation file.
