It is a real computer, not a laptop.
Without a micro or camera and also a relatively old model, my light switch and the socket are not connected in any way.
Still, he wakes up from sleep mode every time I come in and turn on the lights.
How and why is that?
Maybe he has a sensor somewhere that detects when you are moving
Tip into the blue: You have an optical mouse, and it "thinks" it is moved when the light comes on, because the sensor in it stops responding to changes in light.
He is standing in an almost closed cupboard at the other end of the room and is a few years old.
I hardly believe that such a technology is built into it
Or it could be that rather
Unplugged the mouse and tried it
You're right!
