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 did not solve the problem, put the original FRU back in the computer. Do not replace a nondefective FRU. This index can also help you determine the next possible FRUs to be replaced 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 46. Note For IBM devices not supported by diagnostic codes in the ThinkPad notebook computers, see the manual for that device.

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 did not solve the problem, put the
original FRU back in the computer.
Do not replace a
nondefective FRU.
This index can also help you determine the next possible
FRUs to be replaced 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
46.
Note
For IBM devices not supported by diagnostic codes in
the ThinkPad notebook computers, see the manual for
that device.
