1-2 System Overview
NEC Versa SX
The NEC Versa SX notebook computer is a portable system filled with exciting
resources for home, business or travel. Standard features include a powerful
Intel® Pentium 200-MHz or 233-MMX, or the Intel Pentium II 233-MHz,
266-MHz, 300-MHz, 333-MHz, or 366-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 drive or an optional DVD module. As a multimedia system, the NEC
Versa also provides the tools needed to create and present impressive images
using video clips.
To get comfortable with the notebook, read the upcoming sections.
NEC Versa SX notebook computer

System Overview 1-3
The Front of the System
The NEC Versa is compact with features on every side. First, look at the front of
the NEC Versa. The following sections describe front features, beginning with
the liquid crystal display (LCD) panel.
LCD Panel
Your NEC Versa SX comes with a color LCD panel that you can adjust for a
comfortable viewing position. Depending on the model, the system is equipped
with:
 13.3-inch color Thin Film Transistor (TFT) Extended Graphics Array
(XGA) panel.
 14.1-inch color Thin Film Transistor (TFT) Extended Graphics Array
(XGA) panel.
To adjust the LCD panel brightness:
 Press the Fn-F8 and Fn-F9 functions keys to adjust the brightness up or
down. There are 8 levels of brightness.
System Controls and Features
The NEC Versa control panel provides the features shown in the figure. These
features are described after the figure.
System Controls and Features
A- LCD Panel B- Power/Sleep Button C- LED Control Panel
D- Speaker E- Microphone F- Power Status LEDs
G- VersaGlide H- Keyboard

1-4 System Overview
 Operating Status LEDs — keeps you informed of your NEC Versa’s
current operating status. See the following figure and list for each icon’s
meaning.
Operating status LEDs
A- Hard Drive B- VersaBay III C- Caps Lock
D- Scroll Lock E- Num Lock
Hard Drive — lights when the NEC Versa writes to or reads data
from the hard drive.
VersaBay III™ — lights when the NEC Versa writes data to or
retrieves data from a device in the VersaBay III.
Caps Lock — lights when Caps Lock is in effect.
Scroll Lock — lights when Scroll Lock is in effect.
Num Lock — lights when Num Lock mode is active.

System Overview 1-5
Keyboard Panel and Base Unit
The NEC Versa keyboard panel and base unit contain the following features that
are described after the figure.
Keyboard panel and base unit
A -Power/Sleep Button

Power/Sleep Button — press the Power/Sleep button to power on, power
off, and to put the computer into Suspend mode. Your NEC Versa ships
with the button set to Power functionality. To use the Sleep functionality,
refer to “BIOS Setup” in Chapter 2 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, Windows 98, 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. Press the Smart Power switch (Power/Sleep button)
to resume from a save-to-file.
 Keyboard — 85 keys with the standard QWERTY-key layout. (Models
purchased outside of the U.S. and Canada ship with country-specific
keyboard layouts.)
 NEC VersaGlide — The NEC 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 items or actions.
 Stereo 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.
 System 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
yellow/amber to indicate low power condition when operating under
battery power.
Note:
When both the primary and a secondary
battery are installed, the power status LED indicates the
total (primary plus secondary) battery status.

System Overview 1-7
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.
IR Port — Use this infrared (IR) port to transfer files between your
NEC Versa and an IR-equipped desktop or notebook computer.
Enable the IR port via the NEC Customize icon on the desktop to
communicate with other IR-equipped devices.
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 NEC 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

PS/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.

Serial Port — Use this port to connect an external modem or other serial
device.

Parallel 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.

External Monitor (Video) Port — Use this 15-pin port to attach an
external monitor to your NEC Versa. You can run the LCD display and
the external monitor simultaneously or run either alone.

1-8 System Overview
 Expansion Port — This port (also called the Docking port) provides a
connection for NEC Versa SX options including the NEC Versa Dock,
and the NEC PortBar.
 DC Power Port — Use the power jack to attach the NEC Versa to a DC
power source, such as the AC adapter or the optional DC car adapter.
 Tilt Feet — Use to elevate the back of the notebook.
 Docking Notch — Allows the notebook to be securely mated with the
NEC Versa Dock and NEC PortBar.
