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 47.
Note:
For a device not supported by diagnostic codes in the ThinkPad Notebooks, see the manual for
that device.
