Sometimes we need to remember
I know users behaviour can be a pain and seem like stupidity.
I supported IT for my team of specialist, brilliantly diagnostic teachers and I've had all of that and more. But they can't be blamed for all of it.
*"There's nothing on the screen". We assume they’re being literal:They assume we mean the stuff that ought to be there (Windows usually) and the strange words that might appear on the screen aren't anything they think should be there. If we ask "Are there any messages/Is there any writing on the screen?" and they still say "no" that is a different matter
*Turning off the screen rather than the actual PC. As I said already, and we've said on here many times. To many users the computer is just a TV that does stuff. And the box is where the work goes to. And you turn the TV off: Not some attached storage box
*"Yes it's plugged in" when it isn't. Less excusable, but to some, perhaps many, it's been plugged in and working for months or years, and the tangle of wires looks the same as it always did- so of course it must be plugged in still. The idea that it might have come loose at the back is probably not even considered, because most everyday appliances don't have a connection removable at both ends, let alone become unplugged ( and they just don't think of the few that do, assuming they do have and are aware of such).
*"The email isn't working" when the whole PC is off. Actually I can't excuse that one. There are limits.
