How do you prevent screen rotation when switch into laptop mode in Windows 10 on Dell XPS 12 2 in 1?

Hi,

Ever since upgrading to Windows 10, the switch on the left side of laptop (Dell XPS 12 2 in 1) that prevented the video screen from flipping around for tablet mode no longer works.

Is there a new driver that supports that switch available for Windows !0.

I did the standard upgrade, so the original driver should be still installed.

The switch would normally if working either allow for screen rotation or lock the screen from being able to rotate.

Does anyone know how to get that ability working again.

I don't if I can no longer use the switch, is there a software setting to prevent the screen from rotating?
Its hard to use this computer without locking screen rotation, the screen rotates unintentionally. That's why Dell abandoned this way of rotating a laptop into tablet mode.

Thank you for your help!
