OK, just a quick question.  There is both a sleep mode and a power off mode.  Now how do you perform each action.  When I want to turn my system off, I just give a quick press up on the power switch, then the screen and system appear to turn off.  But is it in sleep more or is it off?  If I hold the power button up for a few seconds it also seems to turn off, but what is really happening?  Which is which?
