Has anyone tried to jump the power supply in an S4 so it will start up when power is on without having to push the button? So you can reboot a large batch of them all at once?
I dont recommend firing all at once, better if you make remote on and power them separately. You can accomplish this only if you connect two wires directly to the ON button, and than activate them with network replay. Or if you are there on the place with manual switches.
