A day later I got back my charger and the the keyboard and trackpad worked like a charm again. I opened the computer and tried clicking the trackpad cable in place. I used an external keyboard and mouse until I have drained the battery. A day later the keyboard and trackpad had stopped working. It started when I forgot my charger at home and borrowed a MacBook Air charger. It seems like the logic board is turning off the keyboard when it chimes.
The keyboard works before the chime (SMC reset) and does not work after the chime (can not reset PRAM). Please don't fixate on replacing the keyboard and trackpad. I can reset the PRAM with the external keyboard.Ĥ) 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) As I said, I know the keyboard is good.ģ) I can not reset the PRAM using the built in keyboard. I can log into OS X and everything functions normally with an external keyboard and mouse.Ģ) I performed an SMC reset using the built in keyboard. I know for a fact that the keyboard and trackpad are not the problem.ġ) External keyboard and mouse work perfectly fine. For some reason my macbook keyboard and trackpad are completely non-responsive.
