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 part 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 32. 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 part 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
32.
Note:
For IBM devices not supported by diagnostic
codes in the ThinkPad notebook computers,
see the manual for that device.
