QUICK TOUR OF THE NOTEBOOK

Take a moment to become familiar with the locations and functions of all controls. It is rec- ommended 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 2500 Series computer.

Color LCD Display Panel

The notebook has a built-in 12.1 inch passive matrix dual scan DSTN 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 colors, and supports simultane- ous display with an external VGA monitor.

The LCD screen also uses Cold Cathode Fluorescent Tube (CCFT) backlighting which con- sumes most of the power from the notebook. To save battery power, the system has an ad- vanced 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 pressing the “Fn “ key (lower left corner) and the desired brightness or contrast keys (lower right corner) at the same time.

Power Switch/LCD Cover Switch

The power switch 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 switch button serves as a manual resume switch, allowing you to continue your ap- plication work where you left off.

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

On the top of the unit underneath the right hinge is the LCD cover switch button. This but- ton automatically depresses and releases when you lower or raise the LCD display panel. Depending on your power management settings, this button will either switch the notebook to the Suspend mode or will shut off the LCD when you close the cover.

Status Panel and Power Indicator

Directly below the LCD display, in the center near the right hinge, is the Suspend Mode LED displays. These LEDs provide an easy way to determine the current power mode of the unit. Below these two LEDs is a row of seven more. These LEDs light to indicate whether a device is being accessed, whether an operation is being done, or if a certain mode is or has been activated.
