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.  
Symptoms (Verified)Go To
Power failure. (The power indicator does not go on or 
stay on.)“Power System Check” on page 55.
POST does not complete. No beep or error codes are 
indicated.“Power-On Self-Test (POST) Error Message” on page 
57 “Undetermined Problems ” on page 63
POST detects an error and displayed messages on 
screen.“Error Message List” on page 58
The diagnostic test detected an error and displayed a 
FRU code.“Running PQA Diagnostics Program” on page 37
Other symptoms (i.e. LCD display problems or others). “Power-On Self-Test (POST) Error Message” on page 
57

on page 37).
2.
Go to the diagnostic Diskette Drive in the test items.
