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 Error Message List, 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

device, for example, the size of memory installed. Others may indicate problems with a device, such as the
way it has been configured.
