To set up the mini PC to turn on automatically after, for example, a power outage.

1. Access the BIOS (press DEL or F7 on boot).
2. Go to the “Chipset” tab and then “PCH-IO Configuration”.
3. In “State after G3”, select “S0 State”.
4. Save and reboot.

You can test it by unplugging the mini PC and plugging it again.

For a bit of context, G3 state is mechanical off (M-Off). S0 state would be full on and S5 is a soft off (that’s the change applied, to transition to S0 instad of S5).
