Fujitsu T4310 - LifeBook Tablet PC User Manual page 116

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.
Display won't turn on when
the system is turned on or
when it has resumed.
The display does not
close.
The display has bright or
dark spots.
Possible Cause
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)
detected a failure that does
not allow 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.
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.
