NOTE: When using the touchpad, keep it - and your fingers - dry and clean. The touchpad is sensitive to finger 
movement; hence, the lighter the touch, the better the response. Tapping too hard will not increase the

NOTE: By default, vertical and horizontal scrolling is enabled on your touchpad. It can be disabled under 
Mouse settings in Windows Control Panel.
