The Day One Editions were a precursor to the regular green box Xbox One console. So any Black Box Consoles are manufactured before the Green Box Xbox One consoles, so when we take a look at this the Xbox One Day One Edition consoles were rushed. So of course they are going to have issues. There has been a lot of reports of day one consoles being bricked out of the box.
My brothers day one console was plugged in the wall, has proper ventilation and everything, he was playing Ryse this morning and paused it and turned his Xbox 360 on through the consoles HDMI port to see if a friend was on. Suddenly the power brick light went amber then dim amber. He stopped, unplugged it, reseeded everything and hit the power button, the light went white, the power brick light went white and smoke came out of the top of the console. So it was like a power chip burned up in the console or something that regulates power.
Fair warning, that Xbox One Day One Edition Consoles are having issues.
