Possible Cause
The notebook is set for an
external monitor only.
The angle of the display and
the brightness settings are not
adequate for your lighting
conditions.
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.
Power On Self Test (POST)
has detected a failure which
does not allow the display
to operate.
The notebook has gone into
Video timeout, Standby mode,
Suspend mode or Save-to-Disk
mode because you have not
used it for a period of time.
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.
Something is pushing on the
Closed Cover switch.
The system may be password-
protected.
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.
