What could cause my G6 to go completely dead? on 2007 Pontiac G6

I started to back out my G6 yesterday and then the car went completely dead. There is no power what so ever. It's like when the power goes out in your house. Nothing. Any help would be appreciated.

I agree with global. Most likely the battery blew a cell out causing all charge stored within to go bye-bye.
