### Enabling Auto Power On <a href="#enabling-auto-power-on" id="enabling-auto-power-on"></a>

The auto power on feature will turn the POC-500 system back on after a power loss. This can be useful for automatic recovery after a power outage, or applications where the system’s power button is not easily accessible.

1. Power on the unit and immediately press the F2 key a few times to access the BIOS.
2. Navigate to the Power tab.
3. Change the “Power On after Power Failure” option to “S0-Power On”
4. Navigate to the Exit tab.
5. Save Changes and Exit.
6. The unit will now automatically power on when power is connected.

### Disassembly and clearing the CMOS <a href="#disassembly-and-clearing-the-cmos" id="disassembly-and-clearing-the-cmos"></a>

If the system fails to power on or is otherwise unresponsive, clearing the CMOS may help. It will also restore the BIOS to factory defaults.
