PS3 reset button?

May be...

Switching games on the PS3 has included using the PS button on my remote to "quit game" then loading the new game autostarts it. What about an old fashioned reset button to tap after I have taken a game out and put a new one in? The closest I can figure is powering off and back on (That's a waste so I've been using the controller to quit each game first instead.) Maybe this is a nooby question but I got mine as a display model from the game store so there's no manual to refer to. Is there a quick reset using the eject or power button a certain way?

No. You are doing the correct thing by using the controler.

Tap the power button instead of holding it down. That will reset the console.
