Troubleshooting
This chapter list the POST error indicators and BIOS beep codes, as well general troubleshooting instructions.

POST Error Indicators

When a system error is detected during POST (Power On Self Text), the Setup Utility will switch to diagnostic
mode and will either:
• Displays a POST error message, or
• Emits a series of beep codes

POST Error Messages

POST error messages tell users what failure the system has detected. Some error messages could be related
to a hardware device. Others may indicate a problem with a device configuration. In some cases an error
message may include recommendations for troubleshooting or require that you press the Enter key to display
recommendations. Follow the instructions on the screen. It is recommended that you correct the error before
proceeding, even if the computer appears to boot successfully.
The table below lists the messages that the BIOS has defined and can display.
If your system displays one of the messages marked below with an asterisk (*), write down the code and
message and contact your Acer service provider.
IMPORTANT: If your system fails after you make changes in the Setup menus, reboot the computer, enter
Setup again and load Setup defaults to correct the error.
