Symptom-to-FRU Index
The Symptom-to-FRU Index lists error symptoms and
possible causes. The most likely cause is listed first.
Always begin with “General Checkout” on page 2. This
index can also be used to help you decide which FRUs to
have available when servicing a computer. If you are
unable to correct the problem using this index, go to
“Undetermined Problem” on page 79.
Notes
Ÿ
If you have both an error message and an
incorrect audio response, diagnose the error
message first.
Ÿ
If you cannot run the diagnostic tests, but did
receive a POST error message, diagnose the
POST error message.
Ÿ
If you did not receive any error message, look for
a description of your error symptoms in the first
part of this index.
Ÿ
Check all power supply voltages before you
replace the system board. (See “Power Supply”
on page 59.)
Important
1. Some errors are indicated with a series of beep
codes. (See “Beep Symptoms” on page 102.)
2. The processor is a separate FRU from the
system board; the processor is not included with
the system board FRU. (See “Replacing a
System Board” on page 63.)
