Video Problems

The built-in display is blank
when you turn on your
LifeBook notebook.
The notebook turned on
with a series of beeps and
your display is blank.
The display goes blank by
itself after you have been
using it.
The display does not close.
The display has bright or
dark spots.
The display is dark when on
battery power.
Possible Cause
The BIOS CMOS hold-up
battery has failed.
Something is pushing on the
Closed Cover switch.
The notebook is set for an
external monitor only.
The display angle and bright-
ness 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 that does not
allow the display to operate.
The notebook has gone into
Video timeout, Sleep mode, or
Hibernate 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.
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.
The Power Management utility
default is set on low brightness
to conserve power.
