If you continue having issues turning on your Xbox One Wireless Controller, check out this Xbox One Wireless Controller Won't Turn On Problem Page. I had this same issue. Googled a bit and found this, since your question was the first to pop on my searcha nd was unanswered, I figured I would post what helped me. /u/chubbybator. Here is what he said to do : "Turn the xbox on, then hold the power light for 15 seconds. Then connect a controller via usb and press the home button on the controller. Once the box loads fully you should be able to disconnect the controller and everything should work normally again."
