POST Error Indicators

When POST detects a system failure, it either displays a POST error message, or emits a series of beep codes.

POST Error Message

Whenever a non-fatal error occurs during POST, an error message describing the problem appears onscreen. These text messages are displayed in normal video (white text on black background). It shows the details of the error.

The POST error message index in this section lists the error messages and their possible causes. The most likely cause is listed first. The listed error symptoms classified by function.

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 81.

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.

IMPORTANT: If the system fails after you make changes in the Setup Utility menus, reboot the computer, enter Setup, then press F9 to load the Setup defaults to correct the error.
