Hi all. Just a quick question for you all. I just finished upgrading my Mid 2009 Mac Mini from 2GB to 8GB of RAM. In the process, however, what looks like a small IC on the right side of the CD/DVD-ROM drive popped off while opening up the case. It's not the entire little card next to the drive. Just the tiny little IC that looks like a black button with a white case.



Everything is working fine without said piece. Memory shows up fine. Optical drive works. I'm just wondering what this little piece is and if everything should work A-OK without it or if I should go ahead and try to solder it back on.

Thanks in advance,

Grant

OK. It's probably the IR sensor since the . No big loss as I didn't use it anyway! Thanks!
