Back in April, 2012, I purchased a refurbished MacBook Pro, 13", 2.8 Ghz, 4gb RAM, from their online store. I had purchased refurbished Apple products before with no complications. About four months ago, I began noticing my videos were playing with choppy playback. All of my software was current updated. My warranty expires at the end of April, so as a last ditch effort to resolve the problem, I scheduled a Genius Bar appointment on Sunday, April 21. It was determined that I had a hard drive with bad sectors, and the hard drive would be replaced under warranty. No big deal there. Here's the kicker: I received a voicemail on my iPhone from the Genius Bar that a "homemade device" (plastic cover) had been installed in the optical drive and they wanted my permission to remove that device. I immediately called them back and advised them that the machine I had purchased had never been opened by myself or anyone else. The response I got was "Very interesting". I also told them they had my permission to remove anything that shouldn't be there. This is where I am at... The Apple store still has possession of my MacBook Pro. I was at work when I called them back, so I was distracted and didn't have the urgency of asking anything about this "homemade device". Furthermore, I am concerned of my one-year warranty on the laptop, as that expires at the end of April. My question to all of you is, how should I proceed forward with this? I don't like the idea of a foreign "homemade device" implanted in my refurbished MacBook Pro after I have documented proof that I purchased it on Apple's online store and that, according to Apple's website, "We test and certify all Apple refurbished products..." Again, I have never experienced this with Apple refurbs... What would you recommend I do?
