Hardware Diagnostic Procedure

The diagnostic tests described in this chapter are only intended to test 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 recreate the failure by running the diagnostic tests or repeating
thesame operation.
3.
Refer to “Power System check” on page 52 and “Beep Codes” on page 53 to determine which corrective
action to perform.
