I have a 15'' mbp previous generation with the silver keys. I had my trackpad repaired by apple back in March 2010. Since then, these little black smudges and white spots have been appearing behind the lcd screen. The black smudges actually look like dust that got between the screen. I took some pictures and circled them. You can see them better against a white screen. Sorry about the quality of the pics. The first one is the whole screen and the second two are close ups of a black smudge and a white spot. Any idea what these are and is this covered by applecare?
