Touchpad not auto-disabling when Touchscreen is present and external mouse is connected
I recently bought a Dell I15 5557 with touchscreen and I got a issue with its touchpad.
There is an option in Windows 10 which turns off the touchpad when an external mouse is present, but it appears that the touchscreen also counts as an external mouse. As a result, the touchpad is always disabled when this option is turned on, even if an external mouse is not connected.
Is there any way to automatically disable the touchpad when an external mouse is connected and the notebook have a touchscreen?
