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 419. Note: For IBM devices not supported by diagnostic codes of the ThinkPad computers, see the manual for that device.
