SYMPTOM-TO-FRU INDEX
Symptom-to-FRU index
The symptom-to-FRU index lists symptoms and errors and
their possible causes. The most likely cause is listed first.
Note
Perform the FRU replacement or actions in the
sequence shown in the “FRU/Action in Sequence”
column. 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
FRU to be replaced when servicing a computer.
Numeric error codes show the errors detected in POST or
system operation. In the following error codes, n can be
any number.
If no codes are available, use narrative symptoms.
If the symptom is not listed, go to “Intermittent problems”
on page 51.
Note
For IBM devices not supported by diagnostic codes in
the ThinkPad notebook computers, see the manual for
that device.
