Touch Pad is not working

Will sporadically work with the “click” but touch move does not work at all. I tried moving it and pushing down where the contacts are with no improvement. I also tried switching touch pads with another person with the same computer, with no improvements.

The touchpad can stop working for a number of reasons:

  1. any of the input devices not making good contact, so a bad keyboard can affect the touchpad.
  2. power save modes. Powertop can be configured to apply power save profiles to the keyboard and trackpad. Leave these in non-power save mode.
  3. bad connection between midplate and base.

Generally, removing the whole midplate and reinstalling it tends to fix a lot of problems.

If you have a friend’s laptop parts to try with, try using their midplate, midplate cable and all their input modules to find out which part fixes your problem.
