Video Problems

The built-in display is blank
when you turn on your
LifeBook Tablet PC.
The Tablet PC turned on
with a series of beeps and
the built-in display is blank.
The display goes blank by
itself after you have been
using it.
Possible Cause
The Tablet PC is set for an
external monitor only.
Display angle and brightness
settings are not adequate for
your lighting conditions.
Power management timeouts
are set for short intervals and
you didn't see the display go
on and off again.
Power On Self Test (POST)
has detected a failure which
does not allow the display to
operate.
The Tablet PC has gone into
Video timeout, Sleep 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.
