Description
Fixed (hard) disk is not working or not configured properly. Make sure the hard disk is
installed properly. Run BIOS Setup and make sure the hard disk type is correctly identified.
Stuck key on keyboard.
Keyboard is not working.
Keyboard controller failed the test. might require replacing the motherboard (contains the
keyboard controller).
Unlock the system to proceed.
Monitor type is not correctly identified in BIOS Setup.
Shadow RAM failed at offset nnnn of the 64k block at which the error was detected.
System RAM failed at offset nnnn of the 64k block at which the error was detected.
Extended memory is not working or not configured properly at offset nnnn. Update to the
latest BIOS version.
CMOS clock battery indicator shows that the CMOS battery is dead. Connect the AC adapter
for at least 24 hours, then run BIOS Setup to reconfigure the system.
System CMOS has been corrupted or modified incorrectly, perhaps by an application that
changes CMOS data. In response, the BIOS has installed the default Setup values. Use
BIOS Setup to modify these values if needed. If the error persists, check the system battery.
Connect the AC adapter for at least 24 hours; replace the motherboard.
Timer test failed. Replace the motherboard.
Real-time clock failed the BIOS test. Might require replacing the motherboard.
BIOS found the date or time to be out of range, and reset the real-time clock. You might need
to use BIOS Setup to reset the legal date.
Previous POST did not complete successfully. POST loads default values and offers to run
BIOS Setup. If the failure was caused by incorrect values that 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 that specified in CMOS.
Drive A: is present but fails the BIOS POST diskette tests. Make sure the drive is defined with
the proper diskette type in BIOS Setup and that the drive is connected correctly.
Type of floppy drive A: not correctly identified in BIOS Setup.
RAM cache failed and BIOS disabled the cache. May require replacing the motherboard.
A disabled cache slows system performance considerably.
CPU socket number for Multi-Processor error.
