Checkout Guide
Use the following procedure as a guide for computer
problems.
1. Obtain the failing symptoms in as much detail as
possible.
2. Verify the symptoms by attempting to re-create the
failure by running the diagnostic test (refer to
“Running the Diagnostics
Test” on page 27) or by
repeating the same operation.
Note
To run the diagnostics test, refer to “Running the
Diagnostics” on page 27.
If the symptoms are intermittent and cannot be re-created
(and therefore not verified), go to “Symptom-to-FRU
Index” on page 21 and then go to “Intermittent Problems”
on page 26.
3. Use the following table with the verified symptom to
determine which page to go to. Search the
symptoms column, and find the description that best
matches your symptom; then go to the page shown in
the “Refer To” column.
