My sister dropped my MacBook Pro
( early 2011 15 inch) on it's side with her iPhone lightning cable plugged in and it ended up landing on the cable bending my logic board and messing the USB header, the Mac itself still worked, but I couldn't use any ports. From the side-view it looked absolutely borked and had a bulge from the bottom panel being pressed against. I did a complete teardown to relieve any pressure and bent the header back with my finger as far as I could go, but the contacts still didn't look right, and I wasn't going to force it so I tried putting it back together and it booted. But should I try the USB? I don't want to short my board ($800!)
