Troubleshooting
Common Problems
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.
4. If the Issue is still not resolved, see “Online Support Information” on page 185.
