I just opened up my Macbook Pro to clean some of the dust out, and I discovered what appeared to be two boogers stuck on my optibay caddy. The last time the laptop had been opened up, it was at the genius bar getting the battery replaced. I highly doubt that some debris would have gotten all the way into that spot (it's not near the back vent) by itself and stuck itself to the optibay caddy. Anybody here work in the genius bar that can confirm some genius would do this? I also noticed that a little piece appeared to be broken just above the battery. I forgot to take a picture, but it looks like a tiny black bridge held down by two screws on either end. It is just above the battery. There is one on the left-ish side, and noe on the right-ish side. The right one seems to be broken in the middle. Any idea what this does? It doesn't seem to hold the battery down. The other thing was ALL the screws were loose, one to the point of jiggling before I used the screwdriver at all.
