Hello,

I bought my laptop about 3 months ago. About a week or so, I have noticed that on the top left corner there is a some sort of flashing light. I have no idea why or how to fix it and it appears only at the top left corner of the screen. I updated all the drivers but it didn't help. I don't know what else I can do. Maybe someone can help me to figure out what the problem is and how to fix it? I uploaded a short video to show you what the problem is. I hope you can see it as clearly as I can see it. Please help me.

Thanks.
