Symptom-to-FRU index (TP 560Z - 2640)

  Symptom-to-FRU Index

The Symptom-to-FRU Index is a list containing symptoms, errors, 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 in Sequence' column.
If a FRU replacement does 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 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'.

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