Hello all, I have a Macbook Pro here which was reported with keyboard problems and, sure enough, only a couple of the keys seem to work. I was expecting it to be a simple keyboard swap however, on opening it up, I discovered that one of the chips near the monitor connection (bottom left corner, near the fan) is cracked - or at least the lid of it is. The coil inside may or may not be intact. I've uploaded a couple of pictures (sorry neither of them are great - the flash was too bright and the non-flash was too dark). Could this have anything to do with the keyboard failure? Perhaps this chip is still functioning? I noticed, when opening up another Macbook Pro, that the surface of the same chip appears deformed, as if it might also split in time. Does this component get particularly hot? Does anybody know what it does? Thanks in advance. --- Post Merged, Feb 17, 2016 --- Further investigations suggest this is the power controller. The machine appears to be charging at the moment, but is the lid required as a heatsink? Will it likely burn out soon? Could this have anything to do with the keyboard?
