card

hear
five
beeps,
have
the

Problem:

the
TrackPoint

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
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.)
