Chapter 6. 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

final column lists one or more suggested actions or FRUs to replace. Take the
