ha thanks.im running it off batteries until i can get a ac adapter.and i dont think im bumping the battery pack ive sat the controller down and just let it go. i just tried it without a game and it went dead no sound or vibrations and yes it comes right back on when i cycle the switch. thats how i got it to come on in the first place. i spent a good 15 minutes when i got it trying to get it to turn on
