Like kshjalmar, BIOS Settings are perhaps the right Solution:
After 2 Hotfixes from Windows on my brand New AsusVivoBook Flip (14zoll 8GB /256Gb) my Touchpad gave up - No reaction!
Even no Installed Device recognizeable...!!! So if there is no Touchpad at all..
So I tried the "BIOS Check"
(Hold F2 while PC is starting); then under Advanced Settings
the "Internal pointing device" was enabled.((!! Yes it was enabled!)
So i switched the parameter to "disabled" and back to "enabled" and Saved BIOS with "Save and Exit"
WONDER:
Touchpad was running as good as before the Hotfixes...
