Keyboard and trackpad issues
Original task: replace the battery in computer A. When done, the keyboard worked, but not the trackpad. I happen to have a spare MBP (computer B), missing only the trackpad cable. Verified that trackpad and keyboard in B worked with cable A. Swapped trackpads: computer A, with cable A and trackpad B - neither keyboard nor trackpad worked. ordered new trackpad and 2 x cables. A with new TP and cable: keyboard works, not trackpad.
Does anyone have any ideas? Tearing my hair out....
