The CPU has on-chip dual-processing, a local multiprocessor interrupt controller, and power management features. NEC adopted the chip specifically for its pipelined Floating Point Unit (FPU), and local interrupt management. M-Triton System Controller NEC implements Intel’s Mobile Triton technology for several of the notebook’s subsystems including the DRAM controller, Second Level Cache Controller and PCI Bus interface. The Mobile Triton PCIset features include: ■ h yper page mode DRAM support (7-3-3-3 Reads @ 66 Mhz, 32 MB expansion memory board only) ■ d irect mapped organization-write back policy ■ f ully synchronous 33 Mhz PCI bus interface. 256K X 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 electroni- cally, 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: ■ 2 56 KB memory ■ Q uick-Pulse Programming Algorithm ■ 1 50 nanoseconds (ns) maximum access time ■ E TOX Nonvolatile flash technology ■ C MOS low power consumption ROM BIOS The system uses a Flash ROM known as the system's ROM BIOS to store machine lan- guage programs. The BIOS size is 256 KB, consisting of the system utility (PCMCIA, Auto Setup), system BIOS, video BIOS, and power management. 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., 1-20 Technical Information 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. VGA Controller The Chips and Technologies 65550 integrates a flat panel CRT GUI accelerator and multi- media engine. The controller provides advanced power management that helps to minimize power usage in: ■ n ormal operation ■ S uspend mode ■ p anel off power saving modes. Parallel Interface The PC87338VLJ chip is a 100-pin 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 PC87338VLJ chip operations include: ■ I SA compatibility ■ l ow-power CMOS with enhanced power-down mode Keyboard Controller The keyboard controller (M38813E4HP) supports a PS/2-style keyboard, mouse and se- curity 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, 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 Texas Instruments PCI1130 controller interfaces with the PCI bus, PCMCIA card socket and configuration registers to provide:, Technical Information 1-21 ■ C ardBus slots with hot insertion and removal ■ i ndependent Read and Write buffers for each direction ■ b urst transfers to maximize data throughput on the PCI CardBus bus. Sound Integrated Circuit The Creative Vibra™ 16S VLSI chip is a single combo chip. This dynamic audio circuitry provides the following: ■ I SA 16-bit bus interface chip ■ a udio digital processor ■ h igh performance 16-bit Sigma Delta Stereo Codec ■ S ound Blaster™ 16 register compatible mixer with AGC ■ b uilt-in analog joystick quad timer. Interrupt Controllers Using interrupts, it is possible to change the system’s code sequence. To change the se- quence, reassign the interrupt-levels. Fifteen interrupts can be used with a cascade connec- tion of 8259INTC x 2. Interrupt-level assignments 0 through 15 are listed in Table 1-4, in order of decreasing pri- ority.

Set some features to function automatically or activate them manually with the keyboard or a button. It is wise to keep Power Management features enabled, even when using AC power. The system arrives set up with many power-saving features already enabled. See the follow- ing table. Table 1-5 Automatic Power-Saving Features Default Device Timeout Comment LCD backlight 2 minutes B acklight turns off after there is no keyboard or VersaGlide input for the specified timeout. Hard disk30seconds H ard disk motor stops when hard disk is not accessed for specified timeout. Standby 4 minutes S ystem enters Standby mode after total system inactivity. You can change the timeout period for any of the devices using Setup. See Section 2 for Setup utility procedures., Technical Information 1-23 The NEC PowerPanel Utility icon also allows you to change the timeout period for some of these devices. See Section 2, Setup and Operation for an overview of PowerPanel. Use the Fn F7 key combination to set the power management level. The faucet icon changes when the power management setting changes. You can toggle between Highest Perform- ance, Longest Battery Life, Custom Power Management, and Off. Default values change depending on the type of power management you use. NOTE: Some power management features are unavailable when an NEC docking station is con- nected. System Power Management The system power management consists of the following operation modes. These modes are: ■ A ctive Mode In active mode, the system uses maximum power. It operates with the default clock speed. The system continues to run at this speeds unless overwritten by the power management features. ■ S uspend Mode Suspend mode causes the CPU power down, local devices to shut down, and register values to be stored in RAM. System RAM is put into a slow refresh state. The system resumes Active mode when you press the Suspend button, the system detects a modem ring, or the system is set to resume at a certain time of day. (The system will not resume Active mode if a PCMCIA modem detects a ring.) Sus- pend mode lets you save power without first saving the working data. Press the Suspend button to enter Suspend mode when you need to be away from the system for a short period of time and want to return to where you left off. ■ S tandby Mode The system switches automatically to Standby mode. This eliminates unnecessary power consumption when you operate the system on bat- tery power or AC. Standby mode shuts down the LCD panel, providing privacy as well as power savings. Local Power Management Use Auto Setup to select one of four power management settings for local devices. These include Longest Battery Life, Highest Performance, Custom Setup, and Power Management Off. The power management levels are also available during AC operation. The NEC Versa 6000 computer ships with Longest Battery Life as the default power management setting. See Section 2 for specific procedures on using Auto Setup to select the power management settings., 1-24 Technical Information 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 High- est Performance setting selects CMOS values that will provide minimal energy savings and a shorter battery life. The custom settings enable end-users to set the timeout values of their choice. The Power Management Off selection terminates all power management timers. Local device timers in the system control power consumption in the LCD and Hard Disk Drive. Table 1-6 shows NEC Versa 6000 series Maximum Performance default power man- agement timers. Table 1-6 Maximum Performance Default Settings Power Management Automatic Suspend H ard Disk Timer L CD Panel Timer Mode L ongest Battery Life 10 minutes30seconds 2 minutes Highest Performance 30 minutes10minutes10minutes Custom10minutes30seconds 2 minutes PLUG AND PLAY The NEC Versa 6000 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 6000 recognizes the devices that have been connected to it. Similarly, you can remove external devices in Suspend mode and the NEC Versa 6000 detects the status when resumed., Technical Information 1-25

POWER SOURCES The NEC Versa 6000 can be powered using three different sources, as follows: ■ t he AC adapter connected to an electrical wall outlet (using AC power) ■ t he battery pack or an optional second battery pack ■ t he optional DC adapter connected to a car cigarette lighter. The following sections summarize the three different ways to power the computer., 2-4 Setup and Operation Using the AC Adapter Use the AC adapter and power cable that came with the NEC Versa 6000 to run the com- puter on alternating current (AC) power, or to recharge the battery pack. Use the AC adapter whenever a wall outlet is nearby. Keep the adapter connected whenever possible. The AC adapter charges the battery whether or not you are using the NEC Versa. Figure 2-4 NEC Versa 6000 AC Adapter See the “Hardware Setup” earlier in this section for steps on connecting the AC adapter. Using the Main Battery Pack The NEC Versa 6000 comes with a rechargeable Lithium Ion (Li-Ion) battery pack. Battery power for lasts for approximately two to four hours with power management features en- abled. The battery pack is easy to install and remove. The NEC Versa 6000 system integrates two tools to help the user keep track of the main (or an optional) battery's power level. These include the percentage LEDs described earlier, and the battery gauge in PowerPanel. Both detect how much battery power remains. See a discussion of PowerPanel at the end of this section. When battery power is very low, the power LED flashes amber. When battery power gets low, do either of the following: ■ P ress the suspend button to put the system in Suspend mode, remove the battery pack, and replace it with a fully charged Li-Ion battery., Setup and Operation 2-5 ■ L eave the battery pack in the system and connect your NEC Versa to the AC adapter and a wall outlet. If you connect the system to AC power and continue to use it, the battery recharges in approximately 2.5 to 7 hours. If you connect the system to AC power and do not use it, the battery recharges in about 2 hours. Customers can also buy an optional NEC Versa 6000 battery charger to quickly charge the battery. See the online Options Catalog for more ionformation. !

Other- wise, the system will boot from either the internal IDE hard drive or the CD-ROM reader, if installed in the VersaBay II. Peripherals The Peripherals screen displays the location of the connection between the system and the Input/Output (I/O) ports. Power Savings The Power Savings screen lets you select the level of power management, suspend mode, and suspend/resume options. NOTE: Some operating systems such as Win- dows for Workgroups and Windows 95 have their own power management software which overrides CMOS settings. In this case, be sure to set your desired power management settings ac- cordingly. ■ P ower Management Under AC Normally, whenever AC power is con- nected to the NEC Versa 6000, power management is disabled. If you enable this option, the system uses the power management mode (on or off) you set using the Power Management option. ■ P ower Savings A "Highest Performance" setting provides the greatest sys- tem performance. "Longest Battery Life" provides maximum power saving, and "Off" disables all power management timers. You can also customize the system's power management by selecting "Custom Settings" and entering values for system timeouts. ■ S uspend Mode Suspend mode has a method of operation called Sus- pend/Resume that stores information in RAM and maintains RAM contents after shutting down all local devices. You also have the option to select Save to File. This saves all your open data files to a special file on the hard disk whenever the system goes into Suspend mode. All your data is automatically recovered from where you left off when you Resume. ■ S uspend Warning Tone This option lets you enable or disable a warning tone when Suspend mode starts. It is best to keep this option enabled. ■ P CMCIA Power This option allows you to turn off power to the PCMCIA slots in order to save system power. The slot's power cannot be turned off if a card is installed in the slot., 2-26 Setup and Operation Security The Security screen lets you set a password to protect your data by allowing your system to boot only after you enter a password. When a system password is set, you must enter the password before you can enter Setup. This feature allows only an authorized user to change system parameters. You are not prompted to enter a password until you set an initial password. Your system is not protected until you enter the initial password. See “Security Options” next, for instructions on setting and using the system password. SECURITY OPTIONS The system supports two types of passwords for system security: ■ s ystem password ■ k eyboard lock hotkey. The following contains instructions for setting and using the password feature. Setting an Initial Password The system password is set using Setup.

Beginning memory test Press A user can stop the memory tests by pressing the the SPACEBAR to terminate the spacebar. memory test, Troubleshooting and Repair 3-5 BEEP CODES Beep codes are used to identify a POST error that occurs when the screen is not available. Once the screen is operating, diagnostic messages are reported to the screen. There are beep codes for both fatal and non-fatal system board errors. N OTE: No beep code is generated if a test is aborted while in progress. However, diagnostic cards can be installed in order to display the contents of the diagnostic port 80h and identify the area of failure. Explanation of Test Terms for Beep Code Table The following terms are used in the Test Performed column of the beep code table. 1. Pattern test - One or more particular patterns are written to a location then read back from the same location. Examples of patterns used are 55h and AAh. If the value read does not match the value written, the test is considered a failure. 2. Rolling ones test - Several patterns are constructed. These patterns represent a one rolling through the given location. For example, to roll a one through three bits, the following patterns would be constructed: 001, 010, 011, 100, 101, 110, and 111. The patterns are written to the location and then read back, one by one. If the value read does not match the value written, the test is considered a failure. 3. Rolling zeros test - Several patterns are constructed. These patterns represent a zero rolling through the given location. For example, to roll a zero through three bits, the following patterns would be constructed: 011, 001, and 000. The patterns are written to the location and then read back, one by one. If the value read does not match the value written, the test is considered a failure. 4. Checksum test - All of the values in a given range of locations are added to- gether. The range includes a location which when added to sum of the ranges, will produce a known result, such as zero., 3-6 Troubleshooting and Repair

Section 4 Field Service Guidelines

This section contains preventive and corrective maintenance procedures for the NEC Versa 6000 Series notebook computers. The first part of the section describes cleaning procedures and preferred handling procedures for sensitive components (for example disk drives, batter- ies). The second part of the section identifies all field replaceable parts with the remainder of the section containing the removal and replacement procedures for the field replaceable parts. PREVENTIVE MAINTENANCE Preventive maintenance is limited to cleaning the plastic case, the keyboard, and the display screen and cleaning the diskette drive heads as required. N OTE: Remove the battery and disconnect the AC adapter before performing any maintenance. Voltage is present inside the system unit and LCD even after the system is turned off. Cleaning the Notebook’s Exterior Use the steps below to clean the outer surface of the system. 1. Power off the system and remove the primary battery pack. Unplug all cables connected to the system. 2. Wipe the outside of the system unit, keyboard, and display with a soft, clean cloth. Remove stains with a mild, liquid detergent like a common household cleaner. Use glass cleaner to clean the LCD indicator panel. Apply the glass cleaner di- rectly to the cloth and then wipe the LCD indicator panel. Do not use solvents or strong, abrasive cleaners on any part of the system. 3. Clean the keys with a damp cloth. A small, soft-bristle brush may be used to clean between the keys. Make sure to use a damp cloth (not wet) to prevent moisture from seeping between the keyboard and the metal plate, possibly damaging the components under the keys. If the keyboard gets wet, thoroughly dry it before re- assembling the system unit., 4-2 Field Service Guidelines Cleaning the Notebook’s Interior When servicing the inside of the notebook, remove dust and other foreign particles from in- side the system unit as follows. 1. Remove the top cover and keyboard using the disassembly procedures discussed later in this section. 2. Dust or vacuum (with a rubber-tipped nozzle) the inside of the system unit par- ticularly the motherboard surface. Use care to avoid damaging or dislodging any components or cables. 3. Inspect all cables connectors for damage. Ensure that connectors are seated prop- erly before replacing the cover. Protecting the Disk Drives To protect the disk drives and data, back up the system disk periodically on floppy disk- ettes. Periodically use a head-cleaning diskette in the floppy diskette drive to prolong the life of the drive and to help maintain data integrity. Here are some maintenance procedures to use when servicing a hard disk: ■ A lways back up the data files from the hard disk. ■ R un a virus detecting program for possible virus infested area on the hard disk. ■ U se SCANDISK to correct any errors found in the directory and File Allocation Table (FAT). This will also free up space from any unused sectors. ■ N ever turn the computer off when the hard disk is being accessed. ■ N ever move or raise the computer while the hard disk is being accessed, most es- pecially don't jar the hard disk as this may cause a hard disk crash. ■ U se hard disk maintenance programs like DEFRAG under DOS or Norton Utili- ties SPEEDISK programs. These programs reorganize your hard disk by eliminat- ing fragmentation and improves the hard disk access time., Field Service Guidelines 4-3 Handling the Battery Packs The battery packs furnished with the computer require reasonable care and handling to en- sure efficient operation and maximum life. Periodically inspect the battery terminals and the batteries for evidence of corrosion and oxide build-up. To ensure that the battery packs endure normal life cycle, always observe the following pre- cautions when handling the battery packs: ■ D o not drop the battery packs or subject them to excessive shock and vibration. ■ D o not expose the battery packs to direct sunlight, moisture, or chemical com- pounds. ■ D o not disassemble the battery packs. ■ D o not use the battery packs to power other devices. ■ D o not short the battery leads or connect the battery with reversed polarity. ■ N ever attempt to charge the battery packs in any way other than as described in this manual and the User’s Guide. ■ A lways charge the battery packs as soon as possible after a low battery indication. Maintaining the LCD Quality When it comes to screen problems, heat plays a big part. After a good working session, the typical routine is to shut the machine and close the cover. The display surface (no matter what type it is) radiates heat. When you close the cover, you trap the heat against the screen. Make sure to leave the computer's cover open for about ten minutes while the heat disperses, before closing the LCD. REQUIRED TOOLS AND EQUIPMENT All NEC Versa 6000 corrective maintenance procedures can be performed using the follow- ing tools: ■ T weezers ■ S mall flat-head screwdriver ■ S mall Phillips screwdriver ■ S mall Hex-bolt screwdriver, 4-4 Field Service Guidelines DISASSEMBLY AND REASSEMBLY This subsection contains step-by-step disassembly procedures for the system. Reassembly is the reverse of disassembly. Each procedure is supported by a simplified disassembly illus- tration to facilitate removal.
