Hey, the day before yesterday, I could use my laptop without any problems. When I went to bed I shut it off, as I do everytime. But yesterday when I turned it back on there was an icon in the middle of the screen. It hasn't gone away since then. I tried to search what the problem was, but I couldn't find any answer. The icon shows a transparant gray background, with a darker gray square in front of it with a lightblue border. Inside this square, it shows a white laptop. Please help me.
