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.

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
4.
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.
nTilt Feet — Use to elevate the back of the notebook.
