It does not happen all the time, and it has never happened while I was actually using the console. So far it has happened 4 times, I will turn on my xbox either by saying xbox on, or using the controller and the white xbox logo will come on, on the console, then immediately shut off. The power brick changes from white to orange, and I have to boot the system up by pressing the logo on the console and it does a complete reboot. I have tried the power trick, I have plugged it into a wall outlet, the brick and console are both well ventilated. Is anyone else having an issue like this?
