Long story short, my late 2011 MBP's SD card slot doesn't work. I have tried several cards, cleaning the slot, and install various software. I can't get it to work so I am afraid I have a logic board problem. I'd like to have it looked at before my warranty runs out. If a logic board needs replacing, do they replace the entire MBP? My MBP is custom order, so would they find a refurbished computer that is equal to mine or would I get a new one? I just wondering about general replacement policies. And if it matters, I have Apple Care.
