Xbox One keeps turning its self on.

My little brother may be hitting he's only 3 years old, but when it turns on it doesn't make the sound of it turning on, its just on. My Kinect also is not hooked up to the TV so its not on all the time.

Sorry to hear it. Do you have pets? Perhaps one is bumping against the console? What about music/television playing in the background while you are sleeping? Perhaps the console is mis-hearing something that sounds like Xbox On. I know that where I
live there are radio commercials for Rogers TV advertising for their NextBox (sounds like Xbox doesn't it?). I'm sure if the console heard that it would get a little confused.

Alright ill try it tonight and see what happens thanks

The sound is fairly low so if you're in another room or sleeping you wouldn't hear it. Perhaps the issue may very well be with your little brother. Maybe for one night move a coffee table or something in front of the console or turn it around and see if
the problem persists the next morning.

Do you have a kinect?

sometimes it may recognize you and turn on, it happens to me sometimes.
