I tried to upgrade the RAM in my 2011 17" MBP today. The bottom stick went in fine, but I managed to get the second stick stuck - I guess I didn't push the contacts in far enough before pushing the stick down flat into the slot. So not only does it not get recognised, but it is also impossible to remove. I thought I'd try and prise it out again, but in the process managed to tear the foam pad covering the connector from the HDD to the logic board. So, first of all, what is the purpose of the foam pad, and should I be worried about this? Secondly, how can I go about resolving the fact that the RAM is stuck in the slot? If I took it to the Apple Store, how would they be able to help me out? Thanks.
