Chapter 113 Embedded Numeric Keypad The embedded numeric keypad functions like a desktop numeric keypad. It is indicated by small characters located on the upper right corner of the keycaps. To simplify the keyboard legend, cursor-control key symbols are not printed on the keys. NOTE: If an external keyboard or keypad is connected to the computer, the Num Lock feature automatically shifts from the internal keyboard to the external keyboard or keypad.

Chapter 115 Hot Keys The computer employs hot keys or key combinations to access most of the computer’s controls like screen contrast and brightness, volume output and the BIOS Utility. To activate hot keys, press and hold the Fn key before pressing the other key in the hot key combination. Hot KeyIconFunctionDescription Fn-F1 Hot key help Displays a list of the hotkeys and their functions. Fn-F2 Setup Accesses the notebook’s configuration utility. Fn-F3 Power Management Scheme ToggleSwitches the power management scheme used by the computer (function available if supported by operating system). Fn-F4 Sleep Puts the computer in Sleep mode, which can be defined via the advanced section of the Power Management Properties in the Windows Control Panel.

16Chapter 1 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 palmrest provides optimum comfort and support. NOTE: When using an external USB or serial mouse, you can press Fn + r 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. 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.
