Hey Blake,
Bios is up to date ver. 315
I've done the reset to default, too
I've downloaded both Hotfixes from Asus and tried to reinstall them, but it only told that the driver is up to date no futher action needed.
Asus System Control Interface V2: i have'nt found only the driver, only the app in Windows Store
nothing changed regarding to my actions so far.. still no left shift key no fn keys
