IBM THINKPAD 760C/CD (9546) - Manual (Page 291)

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 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 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.
If the symptom is not listed, go to “Undetermined
Problems” on page 290.
Note
For IBM devices not supported by diagnostic codes in
the ThinkPad notebook computers, see the manual for
that device.
