Keyboard and trackpad are unreponsive?

I had the same problem. It started when I forgot my charger at home and borrowed a MacBook Air charger. A day later the keyboard and trackpad had stopped working. I used an external keyboard and mouse until I have drained the battery. I opened the computer and tried clicking the trackpad cable in place. A day later I got back my charger and the the keyboard and trackpad worked like a charm again.

I had a similar problem and was trying to hard SMC reset by opening the Macbook pro and unplugging the battery. This did not help, but after trying this I unplugged the trackpad cable and keyboard cables then plugged them back and it worked! I suspect a loose connection with one of them.

Hi all,

Hey I am having a similar issue. My keyboard stopped working but my trackpad is still working fine. I took it to a repair place and they said that putting in a new keyboard did not fix the issue. They now want to replace the logic part on the mother board and reprogram it. I told them that it could be the cable for the track pad and they said that when they swapped the mother board the keyboard worked fine so it has to be the mother board. When i plugged in an external keyboard, it also didn't work. Not sure what to do. Should I still try to replace the trackpad cable?
