QUICK TOUR OF THE NOTEBOOK

Take a moment to become familiar with the locations and functions of all controls. It is recommended that you first go through the notebook’s user guide for more information on how to operate all of the features.

Main Components

This section describes the main features of the NEC Versa 2700 Series computer.

Color LCD Display Panel

The notebook has either a built-in 12.1-inch passive-matrix dual scan DSTN or a 12.1-inch active-matrix TFT color liquid crystal display (LCD) which you can adjust and tilt to your desired viewing position. The LCD provides 800x600 pixel resolution with a maximum of 256 K colors, and supports simultaneous display with an external VGA monitor. The system also supports view panning when the resolution of the CRT is greater than 800 x 600.

The LCD screen also uses Cold Cathode Fluorescent Tube (CCFT) backlighting which consumes most of the power from the notebook. To save battery power, the system has an advanced power management feature that powers down the LCD when it has not been used for a predetermined amount of time. You can adjust the brightness and contrast level of the LCD by using the slide bars under the LCD panel on the front of the system.

Power Button/LCD Cover Switch

The power button, when pressed, turns on the notebook’s power. Press it again to turn computer power off. Whenever the notebook is in “save-to-file” suspend mode, the power button serves as a manual resume switch, allowing you to continue your application work where you left off.

NOTE

turning off and turning on the power.

Always wait for a few seconds between

The LCD cover switch is connected to the right hinge of the LCD Assembly. This switch automatically depresses and releases when you lower or raise the LCD display panel. Depending on your power management settings, this switch either converts the notebook to the Suspend mode or shuts off the LCD when you close the cover.

Status Panel and Power Indicator

Directly below the LCD display, in the center, is the System Status LED panel. These LED’s provide an easy way to determine the current power mode of the unit. Below these two LED’s, on the system unit display, is a row of five (5) more. These LED’s light to indicate whether a device is being accessed, an operation is being done, or if a certain mode is or has been activated.

Battery Compartment

The battery compartment is on the right side bottom rear of the notebook. It houses the rechargeable NiMH battery pack or Li-Ion battery pack. The battery pack begins charging whenever you connect the AC adapter to the notebook. It is very important to always have the battery installed on the notebook and to have it always charged. Leaving the battery pack out of the unit for a long period of time completely drains the battery cells.

The USB Connector

The USB is a cable bus that supports data exchange between a host computer and a wide range of simultaneously accessible peripherals. The attached peripherals share USB bandwidth through a host scheduled token based protocol. The bus allows peripherals to be attached, configured, used, and detached while the host and other peripherals are in operation. This is referred to as dynamic (or hot) attachment and removal.

The FIR Window

This window allows wireless communication with any IrDA compliant device (such as another IrDA computer or printer) without the use of a cord or cable. This port transmits up to 4 M bits per second.

The Audio Jacks and Thumbwheel Volume Control

Microphone Jack — Connects to an external microphone. Line-In Jack — Connects to a line-in device such as a synthesizer, stereo Walkman, or an

audio CD player. Headphones — Connects to headphones or amplified speakers.

SOLD BY laptopia2005 DO NOT RESELL!!

Thumbwheel Volume Control — Allows the user to precisely adjust the sound volume.

The Fax/Modem

All models of the system feature a built-in (56Kbps capable, K56 felx compliant) fax/modem freeing the PC card slots for other uses.

External Keyboard and PS/2 Mouse Port

The external keyboard and PS/2 mouse port allows you to connect an external full-sized IBM AT-enhanced keyboard or a PS/2 mouse. When an external keyboard is connected, both the built-in keyboard of the notebook and the external keyboard can be used simultaneously.

The NEC Versa 2700 Series also accepts an optional Y-connector adapter allowing simultaneous use of an external AT-enhanced keyboard and a PS/2 mouse. When using DOS or Windows for Workgroups, if an external serial mouse is installed, the VersaGlide is not supported.
