System Introduction
The computer is packed with features that make it as easy to work with as it is to look at. Here are
some of the computer’s features:
1.1 Features
PERFORMANCE
• Intel Pentium
• 64-bit main memory and 512KB external (L2) cache memory
• Large display in active-matrix TFT
• PCI local bus video with 128-bit graphics accelerator
• Flexible module bay (3.5-inch floppy drive or CD-ROM drive or second hard disk drive option)
®
processor with MMX™ technology
• High-capacity, Enhanced-IDE hard disk
• An advanced power management system with two power-saving modes
• Lithium-Ion smart battery pack
• High-speed connectivity
MULTIMEDIA AND COMMUNICATIONS
• 16-bit stereo audio with built-in FM synthesizer and 3D sound effect
• Built-in microphone and dual angled stereo speakers
• Support for simultaneous display on the built-in screen and an external monitor for
presentations
• Full-screen, 30 frames per second, true-color MPEG video playback
• Infrared wireless communication
ERGONOMICS
• Intuitive FlashStart automatic power-on
• Sleek, smooth and stylish design
• Automatic tilt-up (12.1-inch models only), full-sized, full-function keyboard
• Wide and comfortable palm rest
• Ergonomically-positioned touchpad pointing device
EXPANDABILITY
• CardBus PC Card (PCMCIA) slots (two type II/I or one type III) with Zoomed Video port
function
• Mini-dock option with two CardBus PC Card slots (two type II/I or one type III)
• USB port onboard
• Upgradeable memory and hard disk
1.1.2 FlashStart Automatic Power-On
The computer has no on/off switch. Instead it uses a lid switch, located near the center of the
display hinge, that turns the computer on and off automatically.
Lid Switch
Figure 1-1 Lid Switch
When you close the display lid, the computer saves all data either to the hard disk or to memory,
depending on the When Lid Is Closed setting (see section 3.4.1). When all data is saved, the
computer turns itself off. When you reopen the lid, the computer retrieves your data and resumes
where you left off.
1.2 Ports
The computer’s ports allow you to connect peripheral devices to your computer just as you would to
a desktop PC. The main ports are found on the computer’s rear panel. The computer’s left panel
contains the computer’s multimedia ports and PC card slots.
1.2.1 Rear Panel Ports
The computer’s rear panel contains the computer’s main ports and connectors as shown in the
illustration below.

PS/2-compatible device
(PS/2 keyboard, keypad, mouse)
Serial device (serial mouse)
Parallel device (parallel printer, external floppy drive)
adapter, IR-capable printer)
UNIVERSAL SERIAL BUS (USB) PORT
The computer’s USB (Universal Serial Bus) port located on the rear panel allows you to connect
peripherals without occupying too many resources. Common USB devices include the mouse and
keyboard.
FAST INFRARED (FIR) PORT
The computer’s FIR (fast infrared) port located on the rear panel allows you to transfer data to IRaware machines without cables. For example, you can transfer data between two IR-capable
computers, or send data to an IR-aware printer without using a cable.
The infrared port is IrDA-compliant, and can transfer data at speeds of up to 4 megabits per second
(Mbps) at a distance of up to one meter.
To use the infrared port, position two IR-aware devices
such that their IR ports are no more than one meter
apart and offset no more than 15 degrees.
When the two computers are in position, simply begin the data transfer as you normally would. See
your file transfer software for details.
1.2.2 Left Panel Ports
The computer’s left side panel contains the computer’s multimedia ports and PC card slots, as
shown in the illustration on the next page.

PC CARD SLOTS
The computer contains two PC card slots on the left panel that accommodate two type I/II or one
type III PC card(s). Consult your dealer for available PC card options.
MULTIMEDIA PORTS
The computer provides a Mic-In/Line-in port and a Speaker-out/Line-out port on the left panel to
accommodate multimedia audio devices, such as a microphone, speakers, or headphones.
1.2.3 Indicator Lights
The display panel contains a power indicator light and a battery indicator light as shown in the
illustration below.
