Hi, My macbook pro retina charger wing got out suddenly. Now I have only one wing intact, so I can't wrap the cable around nicely anymore. I tried to apply force to get it in, but it wouldn't work without breaking the wing completely. I saw some videos online that there is glue that should be removed (by heat) in order to open the charger, but I'm wondering if I can avoid that procedure and insert somehow the wing? Thanks in advance.
