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 nondefective 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.
