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 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 290. Note For IBM devices not supported by diagnostic codes in the ThinkPad notebook computers, see the manual for that device. Numeric Error Codes Symptom / Error FRU / Action in Sequence 10X 101: Interrupt failure. 102: Timer failure. 103: Timer interrupt failure. 104: Protected mode failure. 105: Last 8042 command not accepted. 107: NMI test failure. 108: Timer bus test failure. 109: Low meg-chip select test. 1.
