NXOE causing unexpected shutdowns

Is your console plugged in directly to the outlet on the wall, or through an extension or surge protector? (support.xbox.com/.../connect-power-supply)

If its plugged into a surge protector, try plugging directly into a wall outlet. This *may* help your issue.

If not, then most likely you will have to send your console for repair at myservice.xbox.com

Hi!

Has the console suddenly shutdown while you were playing?

In this case, make sure the console is placed in a ventilated place. Due to the heat, the fan may become clogged and cause an unexpected shutdown.

I've been having a similar issue as well, though mine shuts off immediately upon signing in during the first time setup (I reset the system to factory settings to try and fix the initial issue,in which the console would start up, display some blank squares
where the ads are supposed to be, and then turn off with no indication of error, just as yours is doing). I sent it to Microsoft to be repaired, but it came back with the issue remaining. This led me to conclude that It had something to with the power supply,
so I tried it with another one and still nothing. My current theory is that the issue was caused by the November update, as the issues began immediately upon downloading it.

I have an image of the error message which displayed immediately after the update if customer support would find it useful.

My 3 month old xbox one shuts off after 15 to 30 minutes. Looking online, I'm not alone with some so frustrated that are walking away burned. I spoke with Best Buy, who sold me the unit from near Microsoft and they suggested I contact xbox support to get
a new unit. I tried to start a "chat" support session and that failed on their side too, wassup? Michael who is helpless in Seattle

I Have had the exact same issue as AmberTitan802. I got the update then I had a fatal system error when I turned it on. I found that if i unplugged my Ethernet, it would boot properly under my account, with the update, but not connected Xbox live. If i plugged
the Ethernet cable back in it would try to connect and it would shut down immediately. I reset it, and after that, on the last step of initial set up when it signs your account into XBL it would shut off. I shipped it off to Texas and they said there was nothing
wrong with it. So when I got it back I tried a friends account and it worked fine. But i still contacted Microsoft and they sent me a brand new replacement console, and get this, IT STILL DOESN'T WORK! Its the same as the old one, all other accounts work fine
but if i try to sign in it just kicks me back to the last profile and if there isn't one it shuts off. It also goes to say that this is only on the Xbox one. My account works fine on the Xbox app for windows 10 and my Xbox 360. I'm so perplexed by this.
