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-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 the 
same operation.
3.Refer to the table below to determine which corrective action to perform.
ProblemSymptomSection to Refer to
Power failure The power indicator does not light up 
or stay lit. “Power System Check” on page 60
POST failure POST does not complete. No beep 
or error codes issued. “POST Error and Beep Codes” on page 
61.
POST detects an error and displayed 
messages on screen.

System Check Procedures
Power System Check
If the system will power on, skip this section. Refer to System External Inspection.
If the system will not power on, do the following:
TCheck if the power cable is properly connected to the system and AC source. 
TCheck if the voltage selector switch is set to the correct voltage setting.
System External Inspection
1.Inspect the LED indicators on the front panel, which can indicate the malfunction.   For the LED locations 
and description of their behaviour, see “System LED Indicators” on page 6.
2.Make sure that air flow is not blocked.
3.Make sure nothing in the system is making contact that could short out power. 
4.If the problem is not evident, continue with System Internal Inspection.
System Internal Inspection
1.Turn off the system and all the peripherals connected to it. 
2.Unplug the power cord from the power outlets.
3.Unplug the power cord from the system.
4.Unplug all peripheral cables from the system. 
5.Place the system unit on a flat, stable surface.
6.Remove the system covers. For instructions on removing system covers, refer to “System Disassembly” 
on page 25.
7.Verify that components are properly seated.
8.Verify that all cable connectors inside the system are firmly and correctly attached to their appropriate 
connectors. 
9.Verify that all components are Acer-qualified and supported. 
10.Replace the system covers. 
11 .Power on the system. 
12.If the problem with the system is not evident, you can try viewing the POST messages and BIOS event 
logs during the system startup.

POST Error and Beep Codes
NOTE: Perform the FRU replacement or actions in the sequence shown in FRU/Action column, if the FRU 
replacement does not solve the problem, put the original part back in the computer. Do not replace a 
non-defective FRU.
The error messages in the following table indicate the BIOS signals on the screen and the error symptoms 
classified by functions. If the symptom is not included on the list, please refer to “Undetermined Problems”. 
NOTE: Most of the error messages occur during POST. Some of them display information about a hardware 
device, e.g., the amount of memory installed. Others may indicate a problem with a device, such as the 
way it has been configured. 
NOTE: If the system fails after you make changes in the BIOS Setup Utility menus, reset the computer, enter 
Setup and install Setup defaults or correct the error.
