NOTE: Illustrations are for reference only. The exact configuration of your PC depends on the model 
purchased.
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 harder will not increase 
the touchpads responsiveness.
NOTE: By default, vertical and horizontal scrolling is enabled on your touchpad. It can be disabled under 
Mouse settings in Windows Control Panel.
