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., Keyboard The built-in, 83-key keyboard (U.S) or 79-key keyboard (UK and Germany) uses the standard QWERTY format.

This chip controller supports fast graphics and I/O processing. The system logic controller adds the following features: !"built-in level 2 cache controller !"integrated active power management !"integrated battery management !"high performance DRAM controller. Flash ROM The N28F020 flash ROM is a 32-pin, plastic lead chip carrier (PLCC). The chip allows easy updates to the system's BIOS if needed. More specifically, the ROM is flashed electronically, installing the latest BIOS revisions to the system. It is possible to reprogram the BIOS up to 100,000 times. See Section 2, Setup and Operation, for BIOS update procedures. The N28F020 provides the system upgrade capability as well as the following: !"2048-kilobit (kb) memory !"Quick-Pulse Programming Algorithm !"150 nanoseconds (ns) maximum access time !"ETOX Nonvolatile flash technology !"CMOS low power consumption !"low noise feature. 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., The BIOS often changes after the product release to provide enhanced features or bug fixes. To acquire the latest BIOS release, the ROM is flashed electronically allowing the BIOS update to occur without removing the ROM. See Section 2, Setup and Operation, for BIOS upgrade procedures. Peripheral Controller The PT86C718 chip controls the Peripheral Controller, IDE Interface, and Interrupt Multiplexer. The chip integrates performance and power-saving features while providing the following: !"8-level 64-bit write buffer to VL bus !"interrupt multiplexing logic !"reset logic. VGA Controller The video architecture is maintained using the C&T65545B1-5 Controller and support logic. The controller supports video standards including EGA and CGA. This powerful circuitry provides the following features for the system via the controller and LCD: !"1-MB VRAM !"true-color and high-color display capability with 640 x 480 resolution !"supports external CRT resolutions up to 1024 x 768 !"hardware windows acceleration !"bit boundary block transfer !"simultaneous LCD/CRT display in 640 x 480 VGA display mode !"optional frame memory !"high resolution graphics support. Video Controller Architecture The video controller architecture is broken down into several modules. The five significant modules include the sequencer, CRT controller, graphics controller, attribute controller and dithering engine. For example, the sequencer manages CPU and display memory timing. The CRT controller controls sync and timing signals. The graphics controller permits the flow of communication between the CPU data bus and the 32-bit internal data bus. The attribute controller produces a 4-bit wide video data stream that refreshes the display., Diskette Controller, Serial Interface, Parallel Interface The PC8733 chip is a 100-pin plastic Thin Quad Flat Plastic (TQFP) chip. The controller changes 8-bit parallel data into serial data and writes the data to the diskette. Conversely, the serial data is transmitted from the diskette into parallel data, where it remains until the read operation takes place. Additional PC8733 chip operations include: !"compatibility with ISA, EISA, and Micro channel architectures !"low-power CMOS with enhanced power-down mode !"supports new 2 Mbps tape drives Keyboard Controller The keyboard controller (M5M44260ATP-7S) supports a PS/2-style keyboard, mouse and security features such as keyboard hot keys and password. Refer to Appendix A for keyboard interface connector pin assignments. When data is written to the output buffer, the controller generates an interrupt (IRQ01 or IRQ12) and requests the CPU to receive the data. The controller automatically adds an 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 for each PCMICA card socket, controlled through power and RESETDRV control registers !"the elimination of interrupt conflicts using interrupt steering. For a list of PCMCIA drivers and utilities, refer to the CARDSOFT directory on the C: drive.,

I/O Addressing The CPU works in conjunction with I/O devices using I/O mapping. Refer to Table Section

2-6 for hex addresses.

Interrupt Controllers Using interrupts, it is possible to change the code sequence. To change the sequence,

reassign the interrupt-levels. Fifteen interrupts can be used with a cascade connection of 8259INTC x 2.

Interrupt-level assignments 0 through 15 are listed in Table Section 2-7, in order of

decreasing priority.

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 on- board 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: Some power management features are unavailable when an NEC docking station is connected. 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., 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: A plug and play operating system and BIOS are required for this option to work.,

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. NOTE: Make sure that the AC adapter is connected at all times. It will continue to charge the battery pack and bridge battery during operation or when the system is turned off. If the AC adapter is used primarily, remove the battery pack to reduce system weight. CAUTION: Only use the AC adapter model provided with the Versa 2000 series system., Connect the AC adapter as follows: 1. Connect the adapter's DC cable to the power connector on the rear of the system. Connect the other end to the AC adapter. Figure Section 2-4 Connecting the AC Adapter 2. Connect one end of the AC power cable to the AC adapter. Connect the other end 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., 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. 1. If power is on, push the suspend switch to put the system in Suspend mode. The bridge battery saves the memory contents and system status. 2. Remove the battery cover. 3. Locate the battery release latch on the bottom of the system. Push the release latch while removing the battery pack from the compartment. Figure Section 2-5 Battery Release Latch Location, 4. Insert the new battery pack into the battery compartment. Push the battery pack into the compartment until it locks into place. Figure Section 2-6 Battery Pack Replacement 3. Replace the battery cover. 4. Exit Suspend mode. Saving Battery Power The system utilizes two power conserving states: Active and Suspend mode. The system automatically switches between these modes to conserve battery power and prolong battery life. To save additional power, use the following guidelines: !"put the system in Suspend mode when you need to leave the system for a short time !"reduce the LCD's brightness using the Fn F5 hot key to toggle the LCD backlight between standard or full !"turn off the system when not in use. The system also integrates automatic power-saving features. Refer to Table Section 2-7 for a complete description., 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.,
