MacBook air keyboard and trackpad unresponsive
I've got an old Macbook Air that boots fine, but when it starts up, the trackpad and keyboard are unresponsive. I'm pretty sure the problem isn't the input hardware, because they work fine with another logic board in the machine. The weird thing is, I'm able to do an SMC reset, so the logic board (820-3023-A in this case), can still receive input. I'm also unable to use an external keyboard and mouse, though I haven't tried bluetooth. I was not able to reset or the PRAM or start in safe mode, only an SMC reset works on this logic board.
Ist dies eine gute Frage?
