P05B-i7-8565U support auto power on when get power supply, but from bios there is no way to set up this function, we need to use Pin Header and connect the two PINS on board.
First, pls prepare a pin header(2.54mm Short Circuit Connector) and crewdriver, if you don’t have pin header, pls purchase locally or online, or contact your Hystou contacts.
Then, remove the screws on the computer’s bottom case.
Then, you can find the 3 pins onboard as marked in below picture.
Put the pin header onto the no.2 and 3 pin will be ok.
Now put your PC case back as before, and the computer will auto power on once connect to power supply.
