Xbox One keeps turning on and off

Sadly, with this, it means that your console can no longer hold a power charge (or something like that). You have 2 things you can do now:

1) Call 1-800-4MyXbox and set up a repair with an agent.

2) Go to myservice.xbox.com and set up a repair on that website.

I personally suggest the 2nd option, as to where it is faster then waiting, and really simple to set up.

Please respond to this thread if you need additional help setting up the repair.

Thanks for the tip. Is there a way to determine if its a hardware issue and are their steps to fix it?

It is possible the console is overheating. You can try a hard reset to see if it will help buy you may need to set it up for a repair.

Hold the power button on the console for 8 seconds or until the power shuts down completely. Unplug the power cord from the back of the console for 5 minutes. Plug the power cord back in and restart the console. Here is the link for requesting a

there are a few threads on this. Mine has shut off 3 times now and I wasn't playing games any of the times it happened.

Hi! If you even performed a factory reset and tested the power brick, I'm afraid this might be due to faulty hardware.
