Symptom-to-FRU index

This section contains following information:
• "Numeric error codes" on page 35
• "Intermittent problems" on page 35
• "Undetermined problems" on page 35
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 tablet.
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 power-on self-test (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 35.
