PLEASE HELP 2007 PRIUS WON'T START

Hello everyone,
So last Saturday I was driving my Prius no problem it's a 2007 with 76k and it had one bar away from a full tank. I then parked it turned it off and went into the store, when I came back the power button would not do anything. Note that the seatbelt, open door, and turn signal dash lights still worked. My head lights and dome lights worked as well. But if I push the button nothing turns on not even the consumption screen. I took my v12 battery to Auto zone and they tested it and said it was fine. I also changed the battery in my keyfob and changed a couple of fuses and nothing has worked please help!
