T Move your finger across the touchpad (2) to move the cursor.

T Press the left (1) and right (4) buttons located beneath the touchpad to perform selection and execution functions. These two buttons are similar to the left and right buttons on a mouse. Tapping on the touchpad is the same as clicking the left button.

T Use the 4-way scroll (3) 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.

OTE: 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 touchpads responsiveness.

rom Hardware:

. Power off the computer.

. Remove the battery pack and measure the voltage between battery terminals 1(+) and 6(ground). See the following figure

. If the voltage is still less than 7.5 Vdc after recharging, replace the battery.

o check the battery charge operation, use a discharged battery pack or a battery pack that has less than 50% f the total power remaining when installed in the computer.

f the battery status indicator does not light up, remove the battery pack and let it return to room temperature. e-install the battery pack.

f the charge indicator still does not light up, replace the battery pack. If the charge indicator still does not light p, replace the DC/DC charger board.

. Reconnect the touchpad cables.

. Replace the touchpad.

. Replace the system board.

fter you use the touchpad, the pointer drifts on the screen for a short time. This self-acting pointer movement an occur when a slight, steady pressure is applied to the touchpad pointer.
