Dell xps12 touch pad frequently re actives itself but the option is still turned off?????
Sounds like you could be confusing two separate functions. E.g. Tap to Click might be a feature which allows the user to "tap" on the Touch pad
anywhere and see the same effect that a normal Touch screen user would have by tapping on the screen in the location where the pointer happened to be at the time. However, some Touchpads no longer have buttons
to support their mouse click emulation but just rely on the user tapping on the Touchpad where the buttons might be expected to be. Therefore, even though you may have disabled the feature which would allow you to tap anywhere on the Touch pad (i.e, "Tap
to click") you might not have disabled the feature which allows you to generate a "Mouse click" according to which side of the touchpad you were tapping on
near the bottom.
Why not just disable the thing entirely and get a real mouse to avoid these uncertainties and confusions? Alternatively, some manufacturers provide a feature which does allow its users to disable
all Touchpad functionality with a temporary toggle, e.g. sometimes using one of the machine's Fn keys. However, that implementation is completely dependent on each particular machine. I don't know if "Dell xps12"
is a sufficient description of your machine's model to allow anyone to try to help you find your user's manual and interpret it for you. Ask Dell?
