This is a kind of peculiar type of issue i have ever faced. My laptop is 2 years old and working pretty good before that problem. I was using windows 8.1. My friend used it for an hour on July 11 this year and then I saw a ugly display button on top-left corner of my screen. It forces my brightness level to the minimum always. I cant fix it at all. I tried switching off adaptive brightness etc. Then I updated it to windows 10 but cound not get rid of it. How can I fix the issue???
