The system powers up, and
displays power on informa-
tion, but fails to load the
operating system. The boot sequence settings
of the setup utility are not
compatible with your
configuration. 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 29.
You have a secured system
requiring a password to load
your operating system. Make sure you have the right password. Enter the
setup utility and verify the Security settings and
modify them as accordingly.
See “BIOS Setup
Utility” on page 29.
An error message is
displayed on the screen
during the LifeBook note-
book 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 60.
Your system display won’t
turn on when the system is
turned on or when the
system has resumed. The system may be password-
protected. Check the status indicator panel to verify that the
Security icon is blinking. If it is blinking, enter your
password.
Your notebook appears to
change setup parameters
when you start it. BIOS setup changes were not
saved when you made them
and exited the BIOS setup
utility returning it to
previous settings. Make sure you select Save Changes And Exit when
exiting the BIOS setup utility.
The BIOS CMOS back-up
battery 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 notebook. Something is pushing on the

The optional Port Replicator is

is plugged in, and the note-
book is set for an external
monitor only. Pressing [F10] while holding down the [Fn] key
allows you to change your selection of 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
only, external monitor only, both built-in display
and external monitor.
The angle of the display and
the brightness settings are not
adequate for your lighting
conditions. Move the display and the brightness control until
you have adequate visibility.
The power management

short intervals and you failed
to notice the display come on
and go off again. Press any button the keyboard, or move the mouse
to restore operation. If that fails, push the Suspend/
Resume button. (The display may be shut off by
