Diagnosing problems
Use the following procedure as a guide for diagnosing notebook 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 or by repeating the same operation.
3 Use the following table with the verified symptom to determine which page
to go to.

products, prototype cards, or modified options can give false errors and invalid
system responses.
