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. 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 227. Notes: For IBM devices not supported by the diagnostic codes in this manual, see the manual for that device. If the LCD is replaced with a new one, see "Digitizer Adjustment" on page 205 to adjust the pen-point pressure. 216 IBM Mobile Systems HMM
