The Pins that the battery connects to inside the macbook have a small wire going to the motherboard. This connection can get very loose, as its just a plug and not soldered. I fixed a macbook by simply putting blu-tac on this to hold it. This fixed my – no battery – random shutdown- shutdown on movement problems completely.
but you lost the warranty…
I don’t see how the warranty would be affected. There’s no documentation to say you can’t open the macbook. There are no tamper proof stickers. Blu-tac is removable. So I dont see the problem with warranty.
