Yesterday I was replacing the housing on my 15.4" Retina MacBook Pro (Mid 2012) (A1398). When I was removing the Logic-board, I broke this little metal parts from one connector. I don't actually know what is that connector for (MagSafe 2 charging port maybe?). Is it important? Is that maybe grounding/earthing? Should I be worried about that and fix it?
MacBook is Working normally but it seems to me that it has some static electrical charge right now. I was reading little bit about that - and it says on forums that electrical charge may appear once the laptop is disassembled.
