Use the following procedure as a guide for computer problems.
NOTE: The diagnostic tests are intended to test this model.  Non-Acer products, prototype cards, or modified 
options can give false errors and invalid system responses.
1.Duplicate symptom and obtain the failing symptoms in as much detail as possible.
2.Distinguish symptom. Verify the symptoms by attempting to re-create the failure by running the diagnostic 
test or by repeating the same operation.
3.Disassemble and assemble the unit without any power sources.
4.If any problem occurs, you can perform visual inspection before you fellow this chapter’s instructions. You 
can check the following:
power cords are properly connected and secured;
there are no obvious shorts or opens;
there are no obviously burned or heated components;
all components appear normal.
5.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 63.
POST does not complete. No beep or error 
codes are indicated.“Power-On Self-Test (POST) Error Message” on 
page 65
“Undetermined Problems” on page 77
POST detects an error and displayed messages 
on screen.“Error Message List” on page 66
Other symptoms (i.e. LCD display problems or 
others).“Power-On Self-Test (POST) Error Message” on 
page 65
Symptoms cannot be re-created (intermittent
