Hey all, My apologies if this is in the wrong forum - I only post here when I need something Last night I noticed my MagSafe power cord wasn't "locking" into place, and I thought maybe there was something in the port. When I looked closely, I saw one of the pins had fallen down. I tipped the macbook on its side and the pin just fell out, so now I'm down to 5 pins rather than 6. I looked into what each pin does; according to wikipedia, it's for grounding. (It was the one on the far right). The computer charges normally and performs normally. Should I bring it to the Apple store just in case? Can something horrible happen without the pin? It's a mid 2012 macbook with the L style adapter. And no, I didn't drop it.
