My Xbox One will not stay turned off. I do not have the Kinect plugged in so there's no issue of the Xbox 'hearing' anything. When I have my Xbox One in Energy Saving mode and I turn it off, it turns itself back on. When I have my Xbox One on Instant On mode and I turn it off, it turns itself back on with a disc read error message:
"Sorry, we can't play this disc. Try an Xbox One game, a music CD, or a movie on Blu-Ray or DVD." Even though I have not put in any disc into the Xbox One.
