Your notebook appears to
change setup parameters
when you start it. BIOS changes were not
saved when you exited. Make sure you select Save Changes And Exit when exiting
the BIOS setup utility.
The BIOS CMOS hold-up bat-
tery has failed. Contact your support representative for repairs. This is not a
user serviceable part but has a normal life of 3 to 5 years.
Video Problems
The built-in display is
blank when you turn on
your LIFEBOOK notebook. The optional Port Replicator
is attached, an external moni-
tor is plugged in, and the sys-
tem is set for an external
monitor only. Pressing [F10] while holding down [Fn] allows you to

change where to send your display video. Each time you
press the combination of keys you will step to the next
choice. The choices, in order are: built-in display, external
monitor, both built-in display and external monitor.
Display angle and brightness
settings are not adequate for
your lighting conditions. Move the display and brightness control until you have good
visibility. Pressing either the [F6] or [F7] keys while holding
the [Fn] key also allows you to change the brightness level.
Power management timeouts
are set for short intervals and
you didn’t see the display go
on and off again. Press a keyboard button or move the mouse to restore oper-
ation. If that fails, push the Power/Suspend/Resume button.
(The display may be shut off by Sleep mode, Auto Suspend
or Video Timeout)
The notebook turned on
with a series of beeps and
the built-in display is blank. POST test has detected a fail-
ure which does not allow the
display to operate. Contact your support representative.
The display goes blank by
itself after you have been
using it. The notebook has gone into
Video timeout, Sleep, or
Save-to-Disk mode because
you have not used it for a
period of time. Press a keyboard button or move the mouse to restore

operation. If that fails, push the Power/Suspend/Resume but-
ton. Check your power management settings.
