Symptom-to-FRU Index
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 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 be used to help you decide the next
possible FRUs to be replaced when servicing a computer.
