Latitude 7390 touchpad and auto-rotate problems

Hi,

I'm searching for advices about my pc. I lost some fonctions after a windows reset.

- Auto-rotate don't work. Even after reinstallation of dell drivers (Intel-Integrated-Sensor-Solution-Driver_7TH4D_WIN_3.10.100.3429_A00_04), an old version dosen't work to. I verify on regedit, all options are activated. Even in tablet & display preferences.

- Touchpad don't work when dell drivers are installed. When I delete it, It works but without some fonctions (zoom) and windows update re-install automatically dell drivers (dell touchpad 10.3201.101.215). Touchpad manager utility from dell doesn't change it.

After 2 acer machines, I never had this kind of problems.

Someone could share ideas for improve it ? I spend two days to find solution.

Many thanks

Raphael
