Power-On Self-Test (POST) error message
The POST error message index lists the error message and their possible causes. The most likely
cause is listed first.
Note: Perform the FRU replacement or actions in the sequence shown in
the FRU/Action column. If the FRU replacement does not solve the
problem, put the original part back in the notebook. Do not replace a
non-defective FRU.
This index can also help you determine the next possible FRU to be replaced when servicing a
notebook.
If the symptom is not listed, see “Undetermined problems” on page 153 .
The following lists the error messages that the BIOS displays on the screen and the error
symptoms classified by function.
Note: Most of the error messages occur during POST. Some of them
display information about a hardware device, such as 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 notebook, enter Setup, and install Setup defaults or
correct the error.
