Possible Cause
Power On Self Test (POST)
has detected a failure which
does not allow the display
to operate.
The system may be password-
protected.
The notebook has gone into
Video Timeout, Standby
Mode, or Hibernate Mode
because you have not used it
for a period of time.
Something is pushing on the
Closed Cover switch.
The power management time-
outs 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 compres-
sion is enabled.
The BatteryAid default is set
on low brightness to
conserve power.

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.
