Hi! I’ve had many people come to me and ask the same question, if your Xbox One makes a sound when you try to activate it, but there is no light on the Xbox and the power brick is holding a solid orange light, it is most likely the end of your power bricks life. Unfortunately, Microsoft and any other gaming store/supplier stock these anymore, so your last resort would be eBay. 2nd option is if your Xbox doesn’t turn on or make a sound, and your power brick turns white, it’s the console. Long story short, in your situation I would say you might need to invest in a new power brick.
