POST Error Messages List
If you cannot run the diagnostics program tests but did receive a POST error message, use “POST Error
Messages List” to diagnose system problems. If you did not receive any error message, look for a description
of your error symptoms in “Error Symptoms List” on page 73
.
NOTE:
When you have deemed it necessary to replace an FRU, and have done so, you must run a total
system check to ensure that no other activity has been affected by the change. This system check can
be done through the diagnostics program.
NOTE: Check all power supply voltages, switch, and jumper settings before you replace the main board. Also
check the power supply voltages if you have a “system no-power” condition.
If you are unable to correct the problem by using the “BIOS Messages List” table and “Error Symptoms List”
table, go to “Undetermined Problems” on page 77.
To diagnose a problem, first find the BIOS error messages in the left column. If directed to a check procedure,
replace the FRU indicated in the check procedure. If no check procedure is indicated, the first Action/FRU
listed in right column is the most likely cause.

CMOS Checksum Error Check the battery and replace if necessary.

ignore the missing keyboard and continue
the boot.
