Hi there! I was playing Xbox One last night and later shut it down. I shut down the console from the settings menu instead of using the controller. After an update months ago, the shutdown behaviour turned to sleep instead of a complete shutdown. Hence, I follow this method to power off the console.
But strangely, instead of a shutdown, it went to sleep and I heard a loud noise from the fan. I turned the console on and saw a black screen.
I held the power button for 7 seconds to shut it down and then powered on. I see the logo, but after that, I see a black screen.
