So the other day I saw my 2 year old put something small into my disc drive on my 2012 13" MBP. I couldn't stop him in time, and now something is in there. (I have no idea what it is) I tried to use gravity to get it out, but I don't even hear anything rattling in there. I tried to put a cd in to see what happens, it makes the noise like its reading the disc and then it spits it back out. I'm still under warranty so I'm wondering if I should just go there and say my disc drive stopped working Any other ideas?
