Problem
The built-in display is blank
when you turn on your
LifeBook Tablet PC.
(continued)
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.
Your display won't turn on
when the system is turned
on or when it has
resumed.
The display does not
close.
Possible Cause
The Tablet PC is set for an
external monitor only.
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.
The system may be pass-
word-protected.
A foreign object, such as a
paper clip, is stuck between
the display and keyboard.
