Touchpad Basics
The following teaches you how to use the touchpad:
TMove your finger across the touchpad (2) to move the cursor. 
TPress the left (1) and right (4) buttons located beneath the touchpad to perform selection and 
execution functions. These two buttons are simila r to the left and right buttons on a mouse. 
Tapping on the touchpad is the sa me as clicking the left button.
TUse the fingerprinter (3) to enroll the computer with  registered fingerprint. This recognition device 
helps prevent unauthorized access by others.
NOTE:  When using the touchpad, keep it -  and your fingers - dry and clean. Th e touchpad is sensitive to finger 
movements; hence, the lighter the t ouch, the better the response. Tapping too hard will not increase the 
touchpad’s responsiveness.
