Symptom-to-FRU index

The symptom-to-FRU index in this section lists symptoms

and errors and their possible causes. The most likely

cause is listed first, in boldface type.

Note: Do the FRU replacement or other actions in the

sequence shown in the column headed “FRU or

action, in sequence.” If replacing a FRU does not

solve the problem, put the original part back in the

computer. Do not replace a nondefective FRU.

This index can also help you determine, during regular

servicing, what FRUs are likely to need to be replaced

next.

A numeric error is displayed for each error detected in

POST or system operation. In the displays, n can be any

number.

If no numeric code is displayed, check the narrative

descriptions of symptoms. If the symptom is not described

there, go to “Intermittent problems” on page 56.

Note

For an IBM device not supported by diagnostic

codes in the ThinkPad notebook computers, see the

manual for that device.
