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.
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 133
.
The following lists the error messages that the BIOS displays on the screen and
the error symptoms classified by function.
Important
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.
Important
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.
Important
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.
