Re: turning a PC on...
I was on a night flight one time and the cabin crew did the usual announcement that the cabin lights would be dimmed, and if you wanted to continue reading then you should turn on the light in the panel above your head.
For the next 30 seconds or so the cabin was filled with the sound of attendant call "ding"s, followed by a further announcement "the button for the light is the one labelled with a picture of a bulb!"
