Versa SX

The Versa SX notebook computer is a portable system filled with exciting

resources for home, business or travel. Standard features include a powerful

Intel Pentium II 266-MHz microprocessor that works together with the latest

Peripheral Component Interconnect (PCI) architecture.

In addition, this system provides a high-performance hard disk drive, diskette

drive or SuperDisk and PC card support. Most models are equipped with a 24X

CD-ROM reader or an optional DVD module. As a multimedia system, the

Versa also provides the tools needed to create and present impressive images

using video clips.

To get comfortable with the notebook, read the following sections.

Around the Front of the System

The Versa is compact with features on every side. First, look at the front of the

Versa. The following sections describe front features, beginning with the liquid

crystal display (LCD) panel.

LCD Panel

Your Versa SX comes with a colour LCD panel that you can adjust for a

comfortable viewing position. Depending on the model, the system is equipped

with:

n14.1-inch colour Thin Film Transistor (TFT) Extended Graphics Array

(XGA) panel.

To adjust the LCD panel brightness:

Keyboard Panel and Base Unit

The Versa keyboard panel and base unit contains the following features that are

described after the figure.

Keyboard panel and base unit

A -Power/Sleep Button

nPower/Sleep Button — press the Power/Sleep button to power on, power

off, and to put the computer into Suspend mode. Your Versa ships with

the power on and power off function, to use the Sleep functionality, refer

to “BIOS Setup” in Chapter 3 for setting up the Power/Sleep functions.

Press the Power/Sleep button to power on.

Hold the Power/Sleep button in place for 5 or more seconds to power

off.

Hold the Power/Sleep button in place for 4 or fewer seconds to put

the system into Suspend mode.

The Power/Sleep button is a “smart” switch, meaning that it recognizes

when the system is in Suspend mode. If in Suspend mode, you cannot

power off until you press the Power/Sleep button again to bring it out of

Suspend mode.

In addition, the Smart Power switch invokes an orderly shutdown in the

Windows 95 and Windows NT environments. If you use the Power/Sleep

button to turn off your system while applications are running, the Smart

Power switch alerts the operating system. The operating system prompts

you to save all data and invokes an orderly shutdown procedure.

1-6 System Overview

Put the unit in Suspend mode when you need to be away from your

system for a short period of time and want to return to where you left off.

Suspend mode shuts down all devices in the system while retaining data

and system status. Use the Fn Power/Sleep key combination to initiate a

manual save-to-file. Hold the Smart power Switch (Power/Sleep button)

in place to resume from a save-to-file. You can find more detailed

information on using Suspend mode in Chapter 3, “Using the Software.”

nKeyboard — 85 keys with the standard QWERTY-key layout. See

Chapter 4 for complete details. (Models purchased in Europe are shipped

with country-specific keyboard layouts.)

nVersaGlide — The VersaGlide works like a standard computer mouse.

Simply move your fingertip over the VersaGlide to control the position of

the cursor. Use the selection buttons below the VersaGlide to select menu

items. VersaGlide settings and features are described in detail in Chapter

nStereo Speakers — provide stereo sound for your multimedia

presentations or listening pleasure. The built-in sound system also

supports 3D sound, which simulates the latest surround-sound

technology.

nSystem Power LEDs — keeps you informed of the system’s current

power status.

System power LEDs

A- Power Status LED B- Battery Charging LED C- Microphone D- IR Port

Power Status LED — lights green to indicate the power is on or

amber to indicate low power condition when operating under battery

power.

System Overview 1-7

Note: When both the primary and a secondary

battery are installed, the power status LED indicates the

total (primary plus secondary) battery status.

Battery Charging LED — lights green for secondary battery or amber

to indicate primary battery charging activity.

Microphone — A strategically positioned built-in microphone allows

you to record monophonic sound directly into your notebook

computer. See Chapter 6, “Using Multimedia,” for details about

recording.

IR Port — Use this infrared (IR) port to transfer files between your

Versa and an IR-equipped desktop or notebook computer. Use the

Windows 95 IRMON utility to communicate with other

IR-equipped devices.

1-8 System Overview

Around the Back of the System

You'll find system ports for connecting optional devices (like printers, docking

station, or external monitor) on the back of your Versa. These ports are

described following the figure.

Ports on the back of the system

A- PS/2 Port B- Serial Port C- Parallel Port D - External Monitor E- Expansion Port

F- DC Power Port G- Tilt Feet H- Docking Notches

nPS/2 Port — Use the standard PS/2 port to connect an external PS/2-style

mouse or a PS/2-style keyboard to the system. With an optional Y-cable

adapter, you can connect both a mouse and a keyboard at the same time.

nSerial Port — Use this port to connect an external modem or other serial

device.

nParallel Port — Use this port to connect a parallel printer or other parallel

device. The port is an Enhanced Capabilities Port (ECP). The ECP

standard provides you with a greater processing speed than the

conventional parallel port. It also supports Enhanced Parallel Port (EPP)

bi-directional and uni-directional protocols.

nExternal Monitor (Video) Port — Use this 15-pin port to attach an

external monitor to your Versa. You can run the LCD display and the

external monitor simultaneously or run either alone.

nExpansion Port — This port (also called the Docking port) provides a

connection for Versa SX options including the Versa Dock, and the NEC

PortBar.

nDC Power Port — Use the power jack to attach the Versa to a DC power

source, such as the AC adapter or the optional DC car adapter.
