Technical Information 1-3

Another video feature includes a CRT port o n t he system's rear panel that allows the user to connect an opt ional monochrome or color external display to the system. The computer can support the LCD and external display simultaneously.

Power- sav ing features for con trolling t he L CD's backlig ht ing in clude th e ROM-based h ot key combination Fn F5, and Auto Setup power management set tings. See Section 2, Setup and Operation, for information on using these settings. In addition, the automatic LCD status featur e conserves the backlight. When the LCD is closed the backlight shuts off automatically, saving battery power.

Power Button

Slide the power butt on to t he right to power on and power off the computer. The power butto n 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 suspend butto n again to bring the system out of Suspend mode.

The battery compartment houses the rechargeable Lithiu m Ion (Li-Ion) battery pack. The battery pack instantly charges whenever you connect the AC adapter t o the notebo ok. It is very important to always have the battery installed in the notebook to insure that it is continuously charged. If the battery pack is uninstalled for a long period of time, the battery cells are drained, causing battery pack to deter iorate.

The ba ttery bay cont a ins a n eight-cell Lithium Ion (L i- Ion) batte ry that lets you run your system on DC power.

Audio Ports and Volume Control

HARDWARE OVERVIEW—INTERNAL COMPONENTS

Review the following sections for a description of the system’s internal hardware.

Battery Pack

The system uses a rechargeable lithium-ion (Li-Ion) battery as its transient power source. The battery pack installs in the compartment next to the VersaBay II on the bottom of the NEC Versa. The battery stor es 14.4 vo lts with a 2600 mAh capacity.

The battery pack powers the NEC Versa for appro ximately 2 to 4 hours. In addition, the user detect s how much battery power is available via the percentage displayed o n t he st atus bar or accessing the Power Gauge utility.

When battery power is getting low, connect the AC adapter t o a wall outlet and recharge the battery. It takes approximately 2 hours to recharge the battery whether or not the syst em is in use.

When battery power is very low, the power LED flashes amber.

Enhanced Parallel Port (EPP).

The user selects between four parallel interface modes using Auto Setup. These include un idir ec tional, bid ire ctiona l, extended or e nhanced. Unid ire ctiona l mode sends data out put from the standard ISA port only. Bidirectional mode sends data using the standard ISA port or PS/ 2 technology. Enhanced mode enables high speed data transmission to occur using either th e u nidire ctional or bidir ec tional modes.

The default parallel port address is 378h and the interrupt level is IRQ07. Pin locations for the parallel interface are listed in Appendix A.

SERIAL INTERFACE

The RS-232C serial port is a 9-pin connector on the system’s rear panel.
