FUJITSU LIFEBOOK U810 - Manual (Page 93)

93 - Troubleshooting
The system powers up,
and displays power on
information, but fails to
load the operating system. The boot sequence settings
of the setup utility are not
compatible with your configu-
ration. Set the operating source by pressing the [ESC] key while the
Fujitsu logo is on screen or use the [F2] key and enter the
setup utility and adjust the source settings from the Boot
menu. See “BIOS Setup Utility” on page 58.
You have a secured system
requiring a password to load
your operating system. Make sure you have the right password. Enter the setup util-
ity and verify the Security settings and modify them as
accordingly. See “BIOS Setup Utility” on page 58.
An error message is dis-
played on the screen dur-
ing the notebook (boot)
sequence. Power On Self Test (POST)
has detected a problem. See the Power On Self Test (POST) messages to determine
the meaning and severity of the problem. Not all messages
are errors; some are simply status indicators. See “Power On
Self Test Messages” on page 96.
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 notebook is set for an
external monitor only. Pressing [A] while holding down the [Fn] key allows you to
change your selection of where to send your display video.
Each time you press the keys you will step to the next choice.
The choices, in order are: built-in display only, external moni-
tor only, 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.
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)
