When I wish to turn my 5400 off completely, I press the power button, see the "Standby" message, but continue to hold the button down and it goes off. I've never really tried to leave it in Standby. But I would have thought that a quick push to get the "Standby" message and then lift off your finger would work. To be honest, I've never tried to leave it in Standby.
Are you keeping your finger on the power button?
I normally leave mine on though.
