So, for my Mom's birthday I bought her some memory. Since she lives out of state, I thought I would walk her through the process of upgrading her memory over Facetime. She was so amazed by the simplicity of how to remove the memory, that she didn't bother to listen to me and wait to put the memory in; instead, rather, she just got overzealous and put the memory in completely unseated. Most would think... oh no problem, just remove it. The problem was it was seated so improperly that the gold contact could be fully seen (and no, she didn't put in the memory backwards. The memory her Macbook takes is, PC3-12800 204-PIN DDR3 1600MHz, same as mine. I bought the Mac version of the crucial memory, 16 GB, that follows the previously mentioned specifications. I have put in the memory myself and had no issues what so ever, but I am much more technologically inclined. In fact, I feel awful for even having her go through this process because although she was successful at unjamming the memory, she broke her plastic clips in the process. The bottom slot is fine and still holds 1x8GB module, but the top can't hold the other module because the module although seated properly in not secure without the plastic clips that hold the module down. The computer boots up fine on the one module and I'm sure would boot up fine with the second, but I feel it is too dicey to run a module unsecured rubbing against the aluminum body of the bottom case. Sorry for that back history... my question is: the plastic tabs that hold the memory in place, is it a replaceable part, or is it molded onto the logic board. I noticed two screws that either hold that part of the motherboard down, or they serve as a way of replacing those tabs. On one hand, I picture Apple when they designed the system to be evil and follow an archaic design where the clips are permanently affixed to the motherboard. On the other hand, it is perfectly ok for a user to upgrade his or her ram, so long as he or she doesn't harm the computer in the process (even with AppleCare). Thus I would imagine that this is not the first, nor last time this has happened and whether or not this issue is fixable. The logic board is fine, it's just those plastic securing tabs. Thanks so much for reading my first post and taking your time to respond!
