rtfm, you say?
i'm unboxing a new pc for a customer, and of course i'm reading the pitiful excuse for a manual that comes with it. most of them these days are leaflets that don't even tell you how to turn the thing off.
but this one's actually a 12-page pamphlet, and it actually gives instructions on how to turn it off! amazing!
but you have to know what the start button is. no screenies to help you along. just ignoring that the start button hasn't said "start" since 2007.
