This unit is out of warranty, so I was hoping the community could provide some support.
The unit works fine with an external mouse, but not otherwise.
Without an external mouse, the touch pad will accept a click but not movement in any direction.
The cursor just sits there in one single position.
I know there are no diagnotsics on the device to test with (at all, much less for the touchpad) and outside of powerwashing I do not know what else to try.
