System Board

The system board (G8TZL) is the primary component in the system. It contains I/O
subsystems and houses the Intel® 486 DX4-75 chip (75 Mhz internal, 50 Mhz external).
The chip controls important functions including power management, direct drive bus
interface and memory management.

System board specifications are listed in Table Section 2-8 at the end of this section.

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 diskette drive assembly. The
battery uses 14.4 volts with a 2700 mAh capacity.

The battery pack powers the Versa 2000 for up to approximately four hours under power
management, and two hours without power management. In addition, the battery pack lets
the user know how much battery power is available via the LEDs on the front of the
system, or the battery gas gauge in Windows.

When battery power is getting low, connect the AC adapter to a wall outlet and recharge
the battery. It takes 1.6 hours to recharge the battery pack when the system is powered off.
It takes 6 to 9 hours to recharge the battery while the system is powered on.

CMOS Battery

The lithium battery (3.6 Volts, 1000 mAh capacity) is connected to CN17A on the system
board. It provides battery backup and prevents data loss in the system’s complementary
metal oxide semiconductor (CMOS) RAM. This memory area contains information on the
system’s configuration like date, time, drives, and memory. The CMOS battery lasts
approximately two years.

Bridge Battery

The bridge battery saves the memory contents and system status for up to 5 minutes while
in Suspend mode. It is connected to the system board via CN 13. The AC adapter maintains
voltage in the bridge battery when the system is powered on or off. The bridge battery
provides 10 Volts, 30 mAH.

PCMCIA Slots

The Versa 2000 provides a 3.3 volt interface for either two Type I/Type II PCMCIA cards,
or one Type III PCMCIA card.

SOLD BY laptopia2005 DO NOT RESELL!!

SOLD BY laptopia2005 DO NOT RESELL!!

Keyboard

The built-in, 83-key keyboard (U.S) or 79-key keyboard (UK and Germany) uses the
standard QWERTY format. The keyboard provides 12 function keys and 8 cursor control
keys, with an Fn key for ROM-based key functions. The numeric keypad is embedded in
the standard key layout.

NEC VersaGlide

The NEC VersaGlide is a built-in mechanism that functions as the system’s mouse. It
controls the on-screen pointer (cursor). To use the VersaGlide, glide your finger across the
NEC VersaGlide pad, and the cursor follows. The buttons on either side of the NEC
VersaGlide allow the user to select or deselect menu items. Double-tap is also supported on
the VersaGlide pad.

The NEC VersaGlide is the system's default pointing device unless a PS/2 mouse is
installed. If an external mouse is installed, then the NEC VersaGlide is deactivated. A
serial mouse is not supported.

SYSTEM MEMORY

The system board provides either 4- or 8-MB of standard random access memory (RAM).
Base memory is 640 KB and extended memory is 3072 or 7168 KB (interleaved),
depending on the system model.

Optional memory cards with a value of 4-, 8-, or 16-MB can be added to increase system
memory up to a maximum of 36- or 40-MB. In addition, 256 KB of read-only memory
(ROM), 1 x 28F020, enables the system BIOS to be flashed.

Memory Map

The system supports system and video shadowing, both controlled through complementary
metal oxide semiconductor (CMOS). The system supports BIOS as a cacheable area with
write protection. Table Section 2-1 lists the system's memory map.

ROM BIOS

The system uses a Flash ROM known as the system's ROM BIOS to store machine
language programs. The BIOS size is 256 KB, which consists of 96 KB system utility
(PCMCIA, Auto Setup), 64 KB system BIOS, 32 KB video BIOS, 32 KB power
management and 32 KB reserved.

The BIOS programs execute the power-on self-test (POST), initialize CPU controllers, and
interact with the LCD indicator panel, diskette drive, hard drive, communication devices
and peripherals. The system BIOS also contains Auto Setup and provides VGA controller
support. The ROM BIOS is copied into RAM (shadowing) for optimum performance.

The ROM BIOS contains both the system and video BIOS. The system BIOS is located in
the upper portion of the device, video BIOS is located in the lower portion. System BIOS is
located between F000h-FFFFh.

even parity bit to the data sent and waits for a response. The device must acknowledge that
the data was successfully received by sending a response to the controller for each byte of
data received.

PCMCIA Controller

The controller (CL-PD6720) interfaces with the ISA bus, PCMCIA card socket and
configuration registers to provide:

memory address mapping, I/O address mapping

POWER MANAGEMENT OVERVIEW

The Versa 2000 series system uses power management features to prolong system battery
life.

The CPU implements a System Management Interrupt (SMI) function that works
transparently with the operating system and application software. When activated, the
processor mode changes to real mode. Unique “SM-RAM” containing power management
software is mapped at address 30000h-3FFFFh. This activity is inherent to the system and
does not require any adjustment to the operating system or application software.

The power management program is located in ROM at location EA000h-0EFFFh. In on­board DRAM, the software is physically allocated at 0D0000h-0DFFFFh.

Use Auto Setup to select specific power management options. For information on how to
select these options, see Section 2.

NOTE:

unavailable when an NEC docking station is
connected.

Some power management features are

System Power Management

The system power management consists of the following operation modes. These modes
are:

Active Mode  In active mode, the system uses maximum power. It operates

!"

with the default clock speed (75 MHz). The system continues to run at this
speeds unless overwritten by the power management features.

Suspend Mode  When the system is powered on, but not in use it enters into

!"

Automatic Suspend mode after a specified amount of time (default timeout is 10
minutes). This shut-down mechanism conserves system power while allowing the
user to return to complete the work at any time.

Or, the system can be put into Suspend mode using the Suspend/Resume switch.
Slide the switch to activate Suspend mode; slide again to resume active mode.

Suspend mode causes the CPU clock to stop, local devices to shut down, and
register values to be stored in RAM. System RAM is put into a slow refresh state.

Local Power Management

Use Auto Setup to select one of four power management settings for local devices. These
include Longest Battery Life, Personal Setup, Maximum Performance and Off. The power
management levels are also available during AC operation. See Section 2 for specific
procedures on using Auto Setup to select the power management settings.

SOLD BY laptopia2005 DO NOT RESELL!!

SOLD BY laptopia2005 DO NOT RESELL!!

When set to Longest Battery Life, CMOS will set local device timeout values, a local
stand-by timeout value, and a suspend timeout value to ensure the longest battery life. The
Personal Setup setting enables end-users to set the timeout values of their choice. The
Maximum Performance setting selects CMOS values that will provide minimal energy
savings and a shorter battery life. The Off selection terminates all power management
timers.

Local device timers in the system control power consumption in the LCD and Hard Disk
Drive.

PLUG AND PLAY

The NEC Versa 2000 has a Plug and Play functionality. This means you can suspend the
system, add an external keyboard, mouse, or monitor, and when you resume working, the
NEC Versa 2000 recognizes the devices that have been connected to it. Similarly, you can
remove external devices in Suspend mode and the NEC Versa 2000 notices the difference
when resumed.

NOTE:

BIOS are required for this option to work.

BIOS Update Utility (BUU)

The BIOS Update utility updates the ROM BIOS version of the system. This software
utility updates the Flash ROM installed on the system board. The utility identifies and
saves the currently installed BIOS version before installing the new version.

To receive the latest BUU diskette (in the U.S. only), call the Technical Support Center at
[phone] or download the BUU by logging onto NEC's Electronic Bulletin Board
System (BBS) and perform the procedures described in the following subsections.

To use the BIOS Update utility, the system configuration must be set to 640 KB of base
memory with the programming voltage enabled.

Precautions

The BIOS Update utility diskette saves the old BIOS version. Make sure the diskette is not
write-protected. If attempting to use a diskette that has updated another unit, a message
warns that the original BIOS may not be restored. If updating more than one system, first
make a copy of the original diskette for each system before using the diskette.

POWER SOURCES

For optimum performance and power conservation, use the AC adapter to power the Versa
2000 series system. Other power sources include the battery pack, the optional car DC
adapter and the optional docking station .

AC Adapter

The AC adapter allows the system to operate with AC power, recharges the battery pack,
and maintains the bridge battery. The internal backup battery allows the system to retain
system parameter information.

Figure Section 2-4 Connecting the AC Adapter

Connect one end of the AC power cable to the AC adapter. Connect the other end

2.

of the AC power cable to a 100- to 240-volt, AC wall outlet.

Battery Power

It is highly recommended to use battery power only when an AC outlet is unavailable. A
fully charged battery pack lasts approximately 5.5 hours under maximum power save
mode, and 2.5 hours without power save mode.

The actual amount of battery time depends on the use of power-saving features, the
application, options installed, and the environment.

Refer to the Battery Status table in the LEDs section for information on determining how
much battery power is currently available.

SOLD BY laptopia2005 DO NOT RESELL!!

SOLD BY laptopia2005 DO NOT RESELL!!

Recharging the Battery Pack

There are two ways to recharge the battery pack, Quick Charge and Normal Charge.
A Quick Charge is performed when the system is off or in Suspend mode with the AC

adapter connected. A Normal Charge is performed when the AC adapter is connected and
the system is on. When the battery status LED shows an orange light or blinking orange
light, it is time to recharge the battery. .

To recharge the battery, simply attach the AC adapter to the system. Charging the battery
pack with a Quick Charge takes 1.6 hours with power off. Charging the battery pack with a
Normal Charge takes 6 to 9 hours with power on. These time increments assume that there
are no options connected to the Versa 2000.

REPLACING THE BATTERY PACK

To replace the battery pack with a fully charged battery, press the suspend button to
activate Suspend mode. It is not necessary to turn off system power as long as Suspend
mode is activated. The bridge battery maintains data and system status for up to 5 minutes
while in Suspend mode. Use the steps below to install a charged battery pack.

AUTOMATIC POWER-SAVING FEATURES

Table Section 2-7 lists the Versa 2000 series automatic power conserving features. These
features work during battery and AC operation. The features listed below do not work
when the optional docking station is connected. Battery life is also maintained by using the
power management levels listed in the next section.

The default timeouts listed below can be changed using Auto Setup. The NEC Power
Center Utility icon also allows you to change the timeout period for some of these devices.

Use the

Fn F7

key combination to set the power management level. You can toggle
between Highest Performance, Longest Battery Life, Custom Values, and Off. You can
modify the custom level for your specific working environment using Custom Values.
Default values change depending on the type of power management you use.

Table Section 2-7 Automatic Power-Saving Features

Device Default (timeout) Description

LCD backlight 2 min. When no keyboard or NEC VersaGlide input

occurs for the specified timeout, the LCD
backlight shuts off.

Hard Disk 1 min. Hard disk motor stops when not accessed for

specified timeout.

Suspend Mode 10 min. The system enters Suspend mode after total

system activity.

Power Saving Levels

The power saving levels work transparent to system applications and can be set by the user
through Auto Setup. See “System Parameters” earlier in this section for information on
using Auto Setup to select power management levels. The two levels for conserving battery
power are as follows.

Active Mode

The system uses full power. All components are turned on and active.

Suspend Mode

Suspend mode conserves power by shutting off all system components while storing RAM contents and
system status. The system returns to Active mode when the suspend button is pressed or if an optional modem
receives data.
