IBM 1400 (2611) , Symptom-to-FRU Index, Numeric Error Codes and Messages

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 should be 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 45.
Note: For any IBM device not supported by the diagnostic
codes in this ThinkPad computer, see the manual
for that device.
