My macbook has a vertical transparent shadow, what is the problem?
Just a week ago, my laptop suddenly has a transparent shadow showing on the screen.
When I charge my laptop the shadow will be blurrier, looks like there is no problem.
But when I remove the charger it looks worse.
(The picture is not mine. I just tried to search in the internet then saw someone having the same problem. So I borrow the his/her picture)
Anyone knows what the problem is? Any advice?
