HP ENVY m6-n012dx Notebook PC.
Using touchpad results in completely erratic mouse movement and clicking. Mouse will shake violently all over screen and even close/open programs, as well as drag around icons. This happens even without any input (touching) the TouchPad. I have tried running all updates, installing drivers, reinstalling drivers, and even rolling back the driver (although, this made it worse). Additionally, I have tried restarting the PC after each driver repair attempt.
None of this has helped. The only work around is to use a third party, USB mouse, but this is very inconvenient for taking the laptop on the go. Using a third party mouse, completely calms down the pointer, and it functions as it is supposed to. However, the second you unplug it, it returns to the erratic movement.
Additionally, I have tried lowering mouse sensativity, and even removing the "tapping" feature, but they have not helped. Again, the mouse will move erratically around the screen, even when the TouchPad is not in use.
Any advise on making this laptop useable without a mouse?
