Chapter 115 Touchpad The built-in touchpad is a PS/2-compatible 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 palm rest provides optimum comfort and support. NOTE: When using an external USB or serial mouse, you can press Fn-F7 to disable the touchpad. If you are using an external PS/2 mouse, the touchpad is automatically disabled. Touchpad basics The following items teach you how to use the touchpad: !Move your finger across the touchpad to move the cursor. !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. !Use the center (2) button (top and bottom) to scroll up or down a page. This button mimics your cursor pressing on the right scroll bar of Windows applications. FunctionLeft buttonRight buttonCenter buttonsTa p Execute Click twice quicklyTap twice (at the same speed as double- clicking a mouse button) Select Click once Tap once Drag Click and hold, then use finger to drag the cursor on the touchpadTap twice (at the same speed as double- clicking a mouse button) then hold finger to the touchpad on the second tap and drag the cursor Access context menuClick once
16Chapter 1 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 harder will not increase the touchpad’s responsiveness.

Chapter 123 NOTE: DC-AC inverter is used to generate very high AC voltage, then support to LCD CCFT backlight user, and is also responsible for the control of LCD brightness. Avoid touching the DC-AC inverter area while the system unit is turned on. NOTE: There is an EEPROM in the inverter, which stores its supported LCD type and ID code. If you replace a new inverter or replace the LCD with a different brand, use Inverter ID utility to update the ID information.
