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 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 (runtime). 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 23.
Note: For any IBM device not supported by the diagnostic
codes in this ThinkPad computer, see the manual for that
device.
