I tried google and all I got was “pressing the power button to turn it off won’t damage it anymore.”
In: Technology
There are two basic solutions, but in both the button is really just a signal, it’s not the actual source of power to the entire device.
In the first, the device is not 100% off, but rather there is a tiny circuit still awake drawing a **very** small amount of power, waiting for the button to be pressed. When it sees the button pressed, it will activate the rest of the machine into waking.
The other solution has the power button run from the power source to a small circuit that is off until briefly powered up when the button is pressed. When it wakes, it will wake the rest of the circuitry and the device will power up.
It’s kind of like someone listening for a bell to ring in a shutdown factory, when they hear it, they will start powering up everything in the building (lights, machinery, etc) and getting it all going. That little bell didn’t ’t do anything, but it woke up the one guy who could turn it all on.
