So, I just had the display on my Macbook pro replaced today due to an issue with the hinges. The work was of course flawless, after all its probably not that hard to change the display, but if you're ever in the Los Angeles Area and need your mac fixed, Mac Enthusiasts is AMAZING. Apple told me it'd be 5-7 days to replace the display after they have the part, Mac Enthusiasts did it in 1! Sorry bout that, still amazed at the service, anywho.. despite the excellent and fast service, I unfortunately discovered a bit of a problem, the optical drive now rattles whenever its in use! I know its supposed to make some noise, but what I'm hearing now is distinctly different then the normal range of sounds. Given that appears that replacing the display doesn't seem to involve touching anything else, as well as the fact that it was working perfectly yesterday, I'm a bit baffled as to how this happened. I suspect something is just loose, but I'm not sure. Mac Enthusiasts appears to only do sales related stuff on the weekend, so I have to wait until next week to take it back to them, in the meantime I was going to take it to the Apple store. Given that most of the genius bar people generally have no clue whats going, I was hoping someone more enlightened might have an idea of the issue and provide some info I can convey to the genius to try and and get this resolved quickly. Thanks!
