Possible Cause
The power management timeouts
may be set for very short intervals
and you failed to notice the
display come on and go off again.
The warning does not apply to
your LifeBook; the driver has
been thoroughly tested and its
installation will not jeopardize
the performance of your system.
Power On Self Test (POST) has
detected a failure which does not
allow the display to operate.
The LifeBook notebook has gone
into Video timeout, Standby
mode, Suspend mode or Hiber-
nation (Save-to-Disk) mode
because you have not used it for a
period of time.
Something is pushing on the
Closed Cover switch.
The power management timeouts
may be set for very short intervals
and you failed to notice the
display come on and go off again.
A foreign object, such as a paper
clip, is stuck between the display
and the keyboard.
If the spots are very tiny and few
in number, this is normal for a
large LCD display.
If the spots are numerous or large
enough to interfere with your
operation needs.
You are running an application
that does not support 800 x 600/
1024 x 768 pixel resolution
display and display compression
is enabled.
Possible Solutions

Display compression gives a clearer but smaller
display for applications that do not support 800 x
600 /1024 x 768 pixel resolution. You can fill the
screen but have less resolution by changing your
display compression setting, (See the Video Features
submenu, located within the Advanced menu of the
BIOS. (See BIOS Setup Utility on page 29 for more
information)
