Hey guys, I have a early 2008 blackbook under warranty (until March 2011). I noticed this problem a little while ago actually, but it's really been bugging me lately: If I turn down my brightness all the way or shut off the screen, I notice imprints in the form of small dots and lines. They dots are aligned to the corners of about two rows of keys. I've tried wiping the screen down and other imprints (oil, I'm assuming) disappear, but these rows just stay there. It was a little hard to take pictures due to reflections, but... Anyways, I plan on bringing it into the Apple store to see what they can do for me. Anyone have this problem before? How di you resolve it?
