Well, update:
Great, nothing seems to have changed.
I pressed Setup on the ATK pckage, removed the ATK, rebooted.
Pressed Setup, installed ATK, rebooted.
Pressed setup Elantech, installed, rebooted.
Everything went back to how it used to be: touchpad doesn't turn on/off with the fn+f9 combo. I can't scroll nor can I zoom with the touchpad. Conclusion; problem remains.
I've built and installed many computers and drivers before. I do know how things work. This is the first time I've stumbled upon a problem where the drivers didn't fix it. Are you guys sure the latest update has this fixed? Cause I can imagine the manufacturer installing the latest updates and this being one of the things they haven't yet fixed.
