I've owned my Macbook Pro since Christmas of last year and its been babied ever since. Its never been dropped or anything. But I've recently come across a problem with my screen. Whenever my screen is black I notice something that looks like a smudge. It almost looks like its broken, but when there's another color but black its fine. Its really hard to describe so I attached pictures. Does anyone know what this can be from and will applecare cover it?
