My Xbox One Console cannot be awaken by my controller at times. I've done all the "degaussing" steps of the "X" button on both the console and controller. I've replaced the console. I've debugged both the controller and console. It is definitely a console issue ... not a controller issue. I bought the console and controller 2 months ago.
This "flakey" condition is also reeling in the game for Halo Master Chief Collection. Twice now, I've had to repeat several missions because the game does not think I've completed a mission, when in reality I've done so. I use the Save and Quit button and the game does not save my progress. Very frustrating in legendary mode.
If I had to guess, it's probably your floating PSU design that allows ground to increase in voltage. Is there a way to ground the power supply?
