Like the title says, when I hit the sleep button on my keyboard, the screen just shuts off, but the computer remains on.
This only happens once in a while, most of the time it will sleep like normal. I can turn the screen back on when I move my mouse, which doesn't work if its actually asleep, as I have it set not to. So it must not actually be asleep, which is clear, but why??
I have to restart the computer to correct this.
Any clue whats going on here??
