HP Spectre x360 Touchpad/Trackpad issue (Erratic + Unresponsive)

[taylorjeff67]

I was having the same problem.

None of the suggestions have worked.

However, I recently disabled 'taps' and that seems to have resolved the problem.

Right-click on the Alps Touchpad icon in the system tray

Click on 'Disable Taps'

Restart (not sure if this is required... but I did it)

Prior to doing this, my touchpad would hang for a second every 10 seconds.  Pretty much unusable. 

Now it seems to function properly.

Good luck.  I hope this helps.
