Use the following procedure as a guide for computer problems.
Note: 
The diagnostic tests are intended to test only Acer products. Non-
Acer products, prototype cards, or modified options can give false 
errors and invalid system responses.
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.
