So my card reader stopped working, so I brought it in to the Apple store. They said they need to replace the Logic Board, so they'll send it in. My question is, what does that all entail? I don't quite know how the Apple portable computers are built. Am I just getting a new motherboard, or is like everything inside being replaced? I.e. CPU, Ram, etc etc. Also is it likely at all that Apple will just decide to give me a new Macbook Pro instead? Thanks!
