System IntroductionSystem Introduction1-1The 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®
 processor with MMX™ technology
· 64-bit main memory and 512KB external (L2) cache memory

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.Figure 1-1Lid 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.Lid Switch 
						

							System Introduction1-31.2 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.1DC-in Port
2PS/2 Port
3Serial Port

adapter, IR-capable printer)12345678 
						

							1-4Service GuideUNIVERSAL SERIAL BUS (USB) PORTThe 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) PORTThe computer’s FIR (fast infrared) port located on the rear panel allows you to transfer data to IR-
aware 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.1PC Card Slots

The computer’s special Fn key, used in combination with other keys, provides “hot-key”
combinations that access system control functions, such as screen contrast, brightness, volume
output, and the BIOS setup utility.Table 1-4Hot Key DescriptionsHot KeyIconFunctionDescriptionFn+EscSuspend-to-memoryEnters suspend-to-memory modeFn+F1
