Symptom-to-FRU Index (8543)

Symptom-to-FRU Index

The Symptom-to-FRU Index lists symptoms and errors and the possible causes. The most likely cause is listed first.

If the computer displays an error message, first replace FRUs listed in the error message. An X in an error message can be any number.

NOTE: If you have an IBM device with its own service manual or a device not supported by the advanced diagnostics tests, refer to the manual for that device.
