The Symptom-to-FRU Index lists the
symptoms and errors and the possible
causes. The most likely cause is listed first.
NOTE: Perform the FRU replacement or actions in the sequence shown in
the FRU/Action columns.
If a FRU did not solve the problem, put the original
part back in the computer.
This index can also be used
to help you decide which FRUs to have available
when servicing a computer.
'Numeric error codes' show the errors detected in POST or
system operation.
In the following error codes, X can be any number.
If no codes are available, use narrative symptoms.
