Symptom-to-FRU Index (9546, 9547)

  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 in Sequence' column. If a FRU did not solve the problem, put the original part back in the computer. Do not replace a nondefective 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. In the following error codes, X can be any number.

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