Display
The large graphics display offers excellent viewing, display quality and desktop performance graphics. The computer supports two different display configurations -- High Performance Addressing (HPA) or Thin-Film Transistor (TFT).
Video Performance
PCI video with 128-bit graphics acceleration and 2 MB video memory boost video performance.
Simultaneous Display
The computer's large display and multimedia capabilities are great for giving presentations. If you prefer, you can also connect an external monitor when giving presentations. This computer supports simultaneous LCD and CRT display. Simultaneous display allows you to control the presentation from your computer and at the same time face your audience. You can also connect other output display devices such as LCD projection panels for large-audience presentations.
Power Management
The power management system incorporates an "automatic LCD dim" feature that automatically dims the LCD when the computer is powered by a battery pack to conserve battery power. See "Power Management" for more information on power management features.
Opening and Closing the Display
To open the display, slide the display cover latch to the left and lift up the cover. Then tilt it to a comfortable viewing position. The computer employs a microswitch that turns off the display (and enters standby mode) to conserve power when you close the display cover and turns it back on when you open the display cover. NOTE: If an external monitor is connected, the computer turns off the display (but does not enter standby mode) when you close the display cover. To close the display cover, fold it down gently until the display cover latch clicks into place. CAUTION: To avoid damaging the display, do not slam it when you close it. Also, do not place any object on top of the computer when the display is closed.

Keyboard
The keyboard has full-sized keys and an embedded keypad, separate cursor keys, two Windows keys and twelve function keys.
Special Keys Lock Keys
The keyboard has three lock keys which you can toggle on and off.
Lock Key Caps Lock Num Lock (Fn-F11)
Description When Caps Lock is on, all alphabetic characters typed are in uppercase. When Num Lock is on, the embedded keypad is in numeric mode. The keys function as a calculator (complete with the arithmetic operators +, -, *, and /). Use this mode when you need to do a lot of numeric data entry. A better solution would be to connect an external keypad. When Scroll Lock is on, the screen moves one line up or down when you press or respectively. Scroll Lock does not work with some applications.
Scroll Lock (Fn-F12)
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.
Desired Access Number keys on embedded keypad Cursor-control keys on embedded keypad Main keyboard keys
Num Lock On Type numbers in a normal manner. Hold Shift while using cursor-control keys. Hold Fn while typing letters on embedded keypad.
Num Lock Off
Hold Fn while using cursorcontrol keys. Type the letters in a normal manner.

IMPORTANT:(for US keyboard users): The keyboard type is set when you first set up Windows. For the Euro symbol to work, the keyboard type has to be set to United States-International. To verify the keyboard type: 1. 2. 3. 4. 5. 6. Click on Start, Settings, Control Panel. Double-click on Keyboard. Click on the Language tab. Verify that the keyboard type used for "English (United States)" is set to United States-International. If not, select and click on Properties; then select United Stated-International and click on OK. Click on OK.

Keyboard Ergonomics
Located below the keyboard, the wide and curved palm rest is ergonomically designed to provide you with a very comfortable place to rest your hands while you type.
Touchpad
The built-in touchpad is a PS/2-compatible pointing device that senses movement on its surface. This means that 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 you connect an external PS/2 mouse, the computer automatically disables the internal touchpad.

Chapter 1
Touchpad Basics
The following items teach you how to use the touchpad: 1. 2. Move your finger across the touchpad to move the cursor. Press the left and right 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.
Function Execute Select Drag
Left Button Click twice quickly Click once Click and hold, then use finger to drag the cursor on the touchpad.
Right Button
Tap Tap twice (at the same speed as double-clicking the mouse button). Tap once Tap twice (at the same speed as double-clicking the mouse button) and hold finger to the touchpad on the second tap to drag the cursor.
Access context menu
