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 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
Problems”.
Note: Most of the error messages occur during POST. Some of them show information about a hardware
device, for example, the size of memory installed. Others may indicate problems 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, please reset the computer.
Enter Setup and install Setup defaults to correct the errors.
