This chapter provides instructions on how to troubleshoot system hardware problems.
Hardware Diagnostic Procedure
IMPORTANT:The diagnostic tests described in this chapter are only intended to test Acer products. Non-
Acerproducts, prototype cards, or modified options can give false errors and invalid
systemresponses.
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 80 and “Beep Codes” on page 81 to determine which corrective
action to perform.
