If your Xbox won't turn off or turns off during startup, this will solve the problem. Also, take the Xbox apart and clean the inside with a can of air and a dry toothbrush. They become very angry inside. You will need a very small torque screwdriver and a small flat head screwdriver. My sons Xbox One S turned on at the Xbox home screen and then turned off, after which it wouldn't even turn on. I cleaned inside and it worked for 5 minutes and shut down again. It took me a while to get this part but it works great.
