Touchpad

The built-in touchpad is a pointing device that senses movement on its surface. This means the cursor responds as you move your finger on the surface of the touchpad. The central location on the palmrest provides optimal comfort and support.

NOTE: If you are using an external USB mouse, you can press Fn-F7 to disable the touchpad.

Touchpad Basics

The following teaches you how to use the touchpad:

T Move your finger across the touchpad to move the cursor.

T Press the left (1) and right (3) buttons located on the edge of the touchpad to do selection and

execution functions. These two buttons are similar to the left and right buttons on a mouse. Tapping on the touchpad produces similar results.

T Use the 4-way scroll (2) button to scroll up or down and move left or right a page. This button

mimics your cursor pressing on the right scroll bar of Windows applications.

NOTE: Keep your fingers dry and clean when using the touchpad. Also keep the touchpad dry and clean. The

touchpad is sensitive to finger movements. Hence, the lighter the touch, the better the response. Tapping too hard will not increase the touchpad’s responsiveness.
