The plastic piece where you plug the battery on the logic board has come off in MacBook Air 13 early 2015 model. I was wondering do I solder it back on or can I glue it because I saw some glue residue when it came off.
Do you mean the plastic on the back of the battery plug or the plug on the board, where you plug the battery in? It’s never good to put glue on a motherboard.
