Symptom-to-FRU Index - ThinkPad 340x / 345x

  Numeric Error Codes

The Symptom-to-FRU Index lists the symptoms, errors, and possible causes. (It can be used to help you decide which FRUs to have available when servicing the computer.) The most likely cause is listed first.

Perform the FRU replacement or actions in the sequence shown in the FRU/Action column. If a FRU does not solve the problem, put the original part back in the computer and perform the next action.

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'

NOTE: For IBM devices not supported by diagnostic codes for the Model 340 and 340CSE, see the manual for that device.
