Power-On Self-Test (POST) Error Message
The POST error message index lists the error message and their possible causes. The most likely cause is
listed first.
NOTE: Perform the FRU replacement or actions in the sequence shown in FRU/Action column, if the FRU
replacement does not solve the problem, put the original part back in the computer. Do not replace a
non-defective FRU.
This index can also help you determine the next possible FRU to be replaced when servicing a computer.
If the symptom is not listed, see “Undetermined Problems” on page 83.
The following lists the error messages that the BIOS displays on the screen and the error symptoms classified
by function.
NOTE: Most of the error messages occur during POST. Some of them display information about a hardware
device, e.g., the amount of memory installed. Others may indicate a problem with a device, such as the
way it has been configured.
NOTE: If the system fails after you make changes in the BIOS Setup Utility menus, reset the computer, enter
Setup and install Setup defaults or correct the error.
