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 did 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 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. If no codes are available, use narrative symptoms. If the symptom is not listed, go to "Undetermined Problems" on page 116. Note For any IBM device not supported by the diagnostic codes in this ThinkPad computer, see the manual for that device.
