I looked at this board and it's a simple push button to turn on. On the bench I set the board on a square of cardboard and connect up the basic parts. No more than are needed for power up. We don't even need a CPU for this round.
I'll use a metal pen tip, jumper or small metal flat screwdriver to complete the power on jumper circuit. I am guessing that new technicians would be looking for a push button switch.
