S***, I'm not as tech savvy as I thought I was. Why must Apple make the insides so hard to access..I've serviced tons of PCs. Anyways, the ribbon cable connection to the keyboard/trackpad has come apart in my hands, and not in the good way (like coming off from the motherboard. I think I'm screwed! I don't suppose anyone knows if I can just replace the cable or do I need to replace the whole top assembly?!
