This is my second MacBook Pro since buying the refresh, the first had a major clicking noise from the HDD, this one has been perfect with regards to how it runs, quiet as a mouse (seriously, it is) and the horsepower is nice when encoding videos and using Creative Suite, however, I have a small, but extremely concerning problem...
I have no idea what it is, but it isn't supposed to be there. It's really quite annoying as its visible when the screen in on, but not when it's off. Nonetheless I didn't expect to have this kind of problem, the screens are a sealed unit right?
What to do?
