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.
System test procedures
Testing the optical drive
Use the following procedure to isolate a problem in an optical drive controller, driver, or
drive.
To test the optical drive:
1 Boot from the diagnostics diskette and start the diagnostics program.
2 Run the CD-ROM Test and see if the test completes successfully.
3 Follow the instructions in the message window.
If an error occurs, reconnect the connector on the system board.
If the error still remains:
4 Reconnect the external optical drive to a USB jack.
5 Replace the external optical drive.
Important
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.
