Description
Fixed disk is not working or not configured properly. Check to see if fixed disk is attached
properly. Run Setup. Find out if the fixed-disk type is correctly identified.
Stuck key on keyboard.
Keyboard not working.
Keyboard controller failed test. May require replacing keyboard controller.
Unlock the system to proceed.
Monitor type not correctly identified in Setup
Shadow RAM failed at offset nnnn of the 64k block at which the error was detected.
System RAM failed at offset nnnn of in the 64k block at which the error was detected.
Extended memory not working or not configured properly at offset nnnn.
Update to the latest BIOS version 2.xx. (Service note 4100-06.)
The CMOS clock battery indicator shows the battery is dead. Connect the AC adapter for at
least 24 hours, replace the motherboard.
System CMOS has been corrupted or modified incorrectly, perhaps by an application
program that changes data stored in CMOS. The BIOS installed Default Setup Values. If you
do not want these values, enter Setup and enter your own values. If the error persists, check
the system battery. Connect the AC adapter for at least 24 hours, replace the motherboard.
The timer test failed. Requires repair of system board.
Real-time clock fails BIOS test. May require board repair.
Previous POST did not complete successfully. POST loads default values and offers to run
Setup. If the failure was caused by incorrect values and they are not corrected, the next boot
will likely fail. This error is cleared the next time the system is booted.
Memory size found by POST differed from CMOS.
