∙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

1.1.2FlashStart 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	Service Guide

1.2Ports

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.

1.2.1Rear Panel Ports

The computer’s rear panel contains the computer’s main ports and connectors as shown in the illustration below.

System Introduction

1-3

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.

1.2.2Left 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.
