Symptom-to-FRU index
This index supports the IntelliStation M Pro computer.
The symptom-to-FRU index lists symptoms, errors, and the possible causes. The
most likely cause is listed first. Use this symptom-to-FRU index to help you decide
which FRUs to have available when servicing the computer.
The first column in each table in this index lists error codes or messages, and the
final column lists one or more suggested actions or FRUs to replace. Take the
action (or replace the FRU) suggested first in the list of the entries in the final
column, and then restart the computer to see if the problem has been corrected.
Notes:
1. Check the configuration before you replace a FRU. Configuration problems can
cause false errors and symptoms.
2. For IBM devices not supported by this index, see the manual for that device.
3. Always start with “General checkout” on page 1.
4. Try reseating a suspected component or reconnecting a cable before replacing
the component.
The POST BIOS code displays POST error codes and messages on the screen.
