Troubleshooting

*Keyboard error nn
BIOS discovered a stuck key and displays the
scan code for the stuck key. You may have to re-
place your keyboard but may be able to use an
external keyboard until then. Contact your sup-
port representative.
*Monitor type does not match CMOS – Run
SETUP
Monitor type not correctly identified in Setup. This
error probably means your BIOS is corrupted,
run the setup utility and set all settings to the
default conditions. If you still get this error, con-
tact your support representative.
#*Operating system not found
Operating system cannot be located on either
drive A: or drive C:. Enter the setup utility and
see if both the fixed disk, and drive A: are prop-
erly identified and that the boot sequence is set
correctly. Unless you have changed your instal-
lation greatly, the operating system should be on
drive C:. If the setup utility is correctly set, your
hard drive may be corrupted and your system
may have to be reinstalled from your back up
media.
*Parity Check 1 nnnn
Parity error found in the system bus. BIOS at-
tempts to locate the address and display it on
the screen. If it cannot locate the address, it dis-
plays ????. This is a potentially data-destroying
failure. Contact your support representative.
*Parity Check 2 nnnn
Parity error found in the I/O bus. BIOS attempts
to locate the address and display it on the screen.
If it cannot locate the address, it displays ????.
This is a potentially data destroying failure. Con-
tact your support representative.
#*Press <F1> to resume, <F2> to SETUP
Displayed after any recoverable error message.
Press the [F1] key to continue the boot process
or the [F2] key to enter Setup and change any
settings.
#*Previous boot incomplete –
Default configuration used
Previous Power On Self Test did not complete
successfully. The Power On Self Test will load
default values and offer to run Setup. If the previ-
ous failure was caused by incorrect values and
they are not corrected, the next boot will likely
fail also. If using the default settings does not
allow you to complete a successful boot se-
quence, you should turn off the power with the
Power Switch and contact your support repre-
sentative.
*Real time clock error
Real-time clock fails BIOS test. May require board
repair. Contact your support representative.
*Shadow RAM Failed at offset: nnnn
Shadow RAM failed at offset nnnn of the 64k
block at which the error was detected. You are
risking data corruption if you continue. Contact
your support representative.
nnnn Shadow RAM Passed
Where nnnn is the amount of shadow RAM in
kilobytes successfully tested.
*System battery is dead – Replace and run
SETUP
The BIOS CMOS RAM memory hold up battery
is dead. This is part of your BIOS and is a board
mounted battery which requires a support rep-
resentative to change. You can continue operat-
ing but you will have to use setup utility default
values or reconfigure your setup utility every time
you turn off your LifeBook notebook.
System BIOS shadowed
System BIOS copied to shadow RAM.
*System CMOS checksum bad – run SETUP
BIOS CMOS RAM has been corrupted or modi-
fied incorrectly, perhaps by an application pro-
gram that changes data stored in BIOS memory.
Run Setup and reconfigure the system.
