- Troubleshooting Your LifeBook
Your notebook appears to
change setup parameters
when you start it.
BIOS setup changes were not
saved when made and you
exited the setup utility.
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 the brightness control until you have
adequate visibility. Pressing either the [F6] or [F7] keys while
holding down the [Fn] key also allows you to change the
brightness level of the display.
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 Standby mode, Auto Sus-
pend or Video Timeout)
The notebook turned on
with a series of beeps and
the built-in display is blank.
Power On Self Test (POST)
has detected a failure 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, Standby
mode, or Save-to-Disk mode
because you have not used it
for a period of time.
Press any button on the keyboard, or move the mouse to
restore operation. If that fails, push the Power/Sus-
pend/Resume button. Check your power management set-
tings, or close your applications and go to the Power Savings
menu of the setup utility to adjust the timeout values to better
suit your operation needs. See “BIOS Setup Utility” on
page 63.
