Diagnosing problems

CHAPTER 4: Troubleshooting
Use the following procedure as a guide for diagnosing notebook problems.
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.
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.
Symptoms (Verified)
Power failure. (The power indicator does
not go on or stay on.)
POST does not complete. No beep or
error codes are indicated.
POST detects an error and displayed
messages on screen.
Other symptoms (LCD display problems
or others).
Symptoms cannot be re-created
(intermittent problems).
