Hello All, Im hoping some of you can help. My MacBook Air battery was dead after a liquid spill, so i changed it and it recognised it and started charging immediately. However when i unplugged the magsafe adapter, it switched off and won't power up via the battery. It is fine from the adapter. There are a few signs of light tarnishing to the components as per pic But nothing that jumps out and says its broken. Is it possible to get hold of circuit diagrams? Thanks!
