POST Error and Beep Codes

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 in the following table 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.
