So if you arelooking for HP Touchpad Drivers, here is the most common drivers that worked for all model, since Syanptic touchpad does not provide seprate drivers for it variant (if there are). Synaptic most of the time tend to make one generic drivers for its toucpad hardware which make it easier for us. The different version might have to do with compatibility and issue but from my experience it just a touchpad with no complicated thing to consider. As long as the touchpad working then i think were good. So this version I think is the most stable of all.
