Eli5: How does a computer turn on with a press of a button if it’s supposed to be completely powered down? How does it get a signal or something that tells it to turn on?
In: Technology
Even if the computer is powered down, the motherboard still receives electricity from the PSU (considering the PSU is on). When you press the power button, you actually just short 2 pins, and this action tells the motherboard to power on the computer.
