For some reason my macbook keyboard and trackpad are completely non-responsive. I know for a fact that the keyboard and trackpad are not the problem.
Here are some other things I have tried:
1) External keyboard and mouse work perfectly fine. I can log into OS X and everything functions normally with an external keyboard and mouse.
2) I performed an SMC reset using the built in keyboard. As I said, I know the keyboard is good.
3) I can not reset the PRAM using the built in keyboard. I can reset the PRAM with the external keyboard.
4) I have tried to leave the Macbook working till the battery dies then leave it for one night without charging and afterwards restarting it with power supply plugged in and they worked but afterwards they in s random startup they return unresponsive (I have tried this for two times and worked and I trying my third time now)
Please don't fixate on replacing the keyboard and trackpad.
The keyboard works before the chime (SMC reset) and does not work after the chime (can not reset PRAM). It seems like the logic board is turning off the keyboard when it chimes. Not sure what could cause this. Does anyone have any ideas?
