Keyboard and touchpad not working on macbook a1181 but power botton work fine
I've found the same problem - keyboard, touchpad and mouse buttons not responsive - and was almost ordering a new KB/touchpad replacement, thinking they were bad. I searched the internet and found that people had already done that with negative results. Studying the KB/touchpad circuit board I found that the controller was a USB device. So I had an idea, why not test it using one external USB port. I soldered the proper wires to a USB plug and connected it to a side USB port and, voil?!, it worked. Then, I removed 2 inductors from the original D+ and D- lines to isolate the KB/touchpad connector and soldered 2 pieces of wire to one of the side USB ports - in sequence, I covered that port with a small aluminum plate to avoid it being used for another device. Reassembled the computer and everything is working fine, back to normal (with one less USB port, of course).
