My Xbox One isnt turning on.

do you have anyone that you could borrow a power brick from to try theirs on your console? also try unplugging the power brick from the mains and from the console for about 5 mins and then try plugging all back in again and try again.

I would try and get hold of another power brick to test first though before buying another.

Regards

Something similar has happened to me a few times and I have had to wait a minute or two before the light went out. I unplug the outer brick from pews and the console and wait then reset. If you have a power strip try resetting that as well.

Hi!

I hope this helps

If you have an Xbox One connected to a power strip, I advise you to remove it and connect it directly to the main socket without additional loads of other equipment. If the problem persists, call assistance
as listed by other comments.

Hi there,

If you do need to replace your power supply remember to buy from a reputable supplier or Microsoft directly, so you know you are buying an original fit for purpose supply unit.
