Video performance
2X AGP video graphic accelerator with 8MB shared from system memory to 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 has built-in AGP and VGA 
display system to support 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.
Dual Display
The computer’s unique graphics chip takes advantage of Windows ME’s multi-display capability, allowing you 
to extend your desktop to an external display device, such as an external monitor projector. With this feature 
enabled, you can move program windows to/from the computer LCD and the external monitor.
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” on 
page 26 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. 
WA R N I N G :
 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.
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.
Lock keyDescription
Caps Lock When Caps Lock is on, all alphabetic characters typed are in uppercase.
Num Lock (Fn-F11) 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.
Scroll Lock (Fn-F12) When Scroll Lock is on, the screen moves one line up or down when you press the 
up or down arrow keys respectively. Scroll Lock does not work with some 
applications.
