IBM N51 Series User Manual

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 did not solve the problem, put the original part
back in the computer. Do not replace a
non-defective part.
This index can also be used to help you decide which
FRUs to have available when servicing a computer.
Note
For IBM devices not supported by the N45
diagnostics, see the manual for that device.
