Power-On Self-Test (POST) Error Message
The POST error message index lists the error message and their possible causes.
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.
The error messages are listed in the coming pages to indicate the BIOS signals on the screen and the error
symptoms classified by functions. If the symptom is not included on the list, please refer to “Undetermined
Problems”.
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.
