I upgraded to windows 10 and I have problem with shutdown. When I shutdown my laptop the screen goes off but the power light keeps on. The laptop is still running and I have to long press power button to shutdown. I thought it was some hardware problem then I reinstalled windows 8 and used for a month then I never got such problem. But I reinstalled windows 10 again and I have this problem again. I did fresh installed with new ISO downloaded from Microsoft. Is there anyway I can solve this?
