Symptom-to-FRU index

This section contains following information:
v "Numeric error codes"
v "Error messages" on page 41
v "Beep symptoms" on page 42
v "No-beep symptoms" on page 42
v "LCD-related symptoms" on page 43
v "Intermittent problems" on page 43
v "Undetermined problems" on page 44
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 43.
