Technical Information

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: Always wait for a few seconds between
turning off and turning on the power.

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.
