The Dell XPS laptop comes with a customisable touchpad. You can turn it off completely if you want to use a mouse, or you can adjust sensitivity, what tapping does and what the buttons do. This is all to improve your experience using the XPS notebook. If at any time you are unsatisfied with your settings, you can restore them back to the original settings and start over.

Select "Hardware and Sound" and then "Mouse."
Select the "Dell Touchpad" tab and click the centre of the window to open the settings.
Select "Button Settings" to enable or disable the touchpad and buttons, and to customise what the buttons do. Click "Apply" and then "OK" to save your changes and close the window.
Open "Scroll Settings" to customise the way you scroll with the touchpad. Click "Apply" to save the changes and "OK" to close the window.
Choose "Touchpad Settings" to customise what your touchpad does with movement and tapping. Click "Apply" and then "OK."
If you want to revert to the original settings, click "Default."
