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 in- terrupt 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:, 1-20 Technical Information hyper page mode DRAM support direct mapped organization-write back policy fully synchronous 30 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: 256 KB memory Quick-Pulse Programming Algorithm 150 nanoseconds (ns) maximum access time ETOX Nonvolatile flash technology CMOS 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 (for PC cards, 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. 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., Technical Information 1-21 VGA Controller The Chips and Technologies 65550A1 is a PCI 64-bit Graphics Accelerator. The integrated programmable linear address feature accelerates the graphics user interface (GUI) perform- ance. The controller also supports Hardware Multimedia and VESA interface standards. The controller provides advanced power management that helps to minimize power usage in: normal operation Standby (sleep) mode panel 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: ISA compatibility low-power CMOS with enhanced power-down mode Keyboard Controller The keyboard controller (M38813E) supports a PS/2-style keyboard, mouse and password security feature. 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., 1-22 Technical Information PC CardBus Controller The Texas Instruments PCI1130 controller interfaces with the PCI bus, PC CardBus socket and configuration registers to provide: compliant with PCI 2.1 and 1995 PC card standards CardBus slots with hot insertion and removal independent Read and Write buffers for each direction burst transfers to maximize data throughput on the PCI CardBus bus. Sound Integrated Circuit The Creative Vibra™ 16C VLSI chip is a single combo chip. This dynamic audio circuitry provides the following: ISA 16-bit bus interface chip audio digital processor Plug and Play support One 46 MHz crystal for Digital Interface, Digital Audio Processor, and Music Synthesizer with a digital to analog converter (DAC) high performance 16-bit Sigma Delta Stereo Codec Sound Blaster™ 16 register compatible mixer with AGC built-in analog joystick quad timer., Technical Information 1-23 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 two 82C59 interrupt controllers. 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 D efault Device Timeout Comment V ideo 2 minutes V ideo turns off after there is no keyboard or VersaGlide input for the specified timeout. Hard Disk 1 minute H ard disk motor stops when hard disk is not accessed for specified timeout. Standby 1 minute 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. Use the FnF7 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 connected to an NEC docking station. For example, the Suspend and Save to File features do not work. The system enters Standby mode if Suspend or Save to File is acti- vated., Technical Information 1-25 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. The system continues to run at this speed unless overwritten by the power management features. Standby 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. Suspend 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 modem detects a ring.) Suspend 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. In addition, to quickly activate the Save to File feature, press the Fn and Suspend button simultaneously. This shuts down the system, and saves the current working data to a file., 1-26 Technical Information 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 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 set- tings. 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 Series Maximum Performance default power manage- ment timers.

Plug and Play is the ability of the BIOS and/or operating system to dynamically assign system resources to a newly installed device without user intervention. For example, you can suspend the system, add an external keyboard, mouse, or monitor, and when you resume working, the NEC Versa recognizes the devices that have been con- nected to it. Similarly, you can remove external devices in Suspend mode and the NEC Versa detects the status when resumed. NOTE: The system must be turned off when installing the CD-ROM reader or diskette drive. Installing these devices in Suspend mode may cause damage to the system., Technical Information 1-27

The following sections summarize the power sources. Using the AC Adapter Use the AC adapter and power cable that came with the NEC Versa to run the computer on alternating current (AC) power, or to recharge the battery pack. Use the AC adapter when- ever a wall outlet is nearby. ! WARNINGDonot attempt to disassemble the AC adapter. The AC adapter has no user-replaceable or serviceable parts inside. Dangerous voltage in the AC adapter can cause serious personal injury or death. The AC adapter is in- tended for use with a computer. Both must meet EN60950 standards. 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 AC Adapter See the “Hardware Setup” earlier in this section for steps on connecting the AC adapter., 2-6 Setup and Operation Using the Main Battery Pack The NEC Versa comes with a rechargeable Lithium Ion (Li-Ion) battery pack. Battery power lasts for approximately two to four hours with power management features enabled. The battery pack is easy to install and remove. Checking Battery Power Levels The NEC Versa system integrates two tools to help the user keep track of the main (or an optional) battery's power level. These include the battery icon located in the tray on the taskbar, and the PowerGauge utility. Using the status bar icons (and percentages) to determine battery status is easy. For exam- ple, if one battery pack is installed, one battery icon appears. If two batteries are installed, two battery packs appear. A blinking battery icon indicates that the battery is charging. A fast blinking battery icon occurs: when installing a new battery during unknown battery status when there is a problem with the battery. Similarly, read the percentages that appear next to the battery icons to find out exactly how much battery power is available. The battery percentage icon blinks under the following conditions: when battery power is low, the number icon blinks. if battery power is extremely low, the number icon blinks rapidly. if the battery has been in storage for a long period of time. To access the PowerGauge utility in Windows for Workgroups systems, select the Power- Gauge Utility icon from the NEC Utilities program group. To access in Windows 95 sys- tems, right click the PowerGauge icon located in the tray on the taskbar. It also starts automatically at power on. What to Do When Battery Power Gets Low When battery power is very low, the power LED flashes amber. When battery power gets low, do either of the following: Press 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 2-7 Leave 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 battery charger to quickly charge the bat- tery. See the online Options Catalog for more information. Returning the Battery to Full Operation To return the battery to its normal state, try the following: remove and then reinstall the battery. reinstall the battery in the NEC Versa, discharge the battery, then fully recharge the battery (to 100%) if the battery in use was in storage for an extended period of time. When to Change the Battery The following symptoms indicate that battery life is nearing an end. Replace batteries that display these symptoms. Shorter work times. Discoloration, warping. Hot to the touch. Strange odor. Battery Handling Keep the following in mind when removing or replacing a battery. Use Li-Ion batteries only in the NEC Versa computer for which they are designed. Turn off power to the system after use. Keeping system power on can degrade battery performance and shorten battery life. Clean the battery terminals with a dry cloth when they get dirty. Keep the battery out of the reach of children., 2-8 Setup and Operation ! WARNING There is a danger of explosion if the battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer. Discard used batteries according to the manufacturer’s instructions.

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. Power Management Under AC Normally, whenever AC power is connected to your NEC Versa system, power management is disabled. If you enable this parameter, the system automatically activates the power management profile you set., Setup and Operation 2-29 Power Savings Level A High Perform setting provides the greatest system performance. Long Battery provides maximum power saving, and Off disables all device timeouts. You can also customize power management by selecting Custom Settings and entering val- ues for device timeouts. Hard Disk Timeout Allows you to select the amount of time before your hard disk shuts down when Power Management is set to custom (set to “On” via Setup). Panel BackLight Lets you select the LCD screen’s backlight intensity. Video Highlight Selects the text intensity at system start up. Video Timeout Allows you to select the amount of time before your video shuts down when Power Management is set to custom.

Save Settings and Exit Accepts changes made to current, or default settings and exits Setup. E xit Without Saving Reverts to previously selected settings and exits Setup. Using Setup to Set Power Management As you have seen in this chapter, Setup allows you to use the factory set power savings level (Longest Life), or choose between High Perform, Custom, or Off. Each provides a special value to your current work effort. These power management levels have been de- signed with you in mind. For example, you can use them under the following circumstances: Longest Life — Provides best battery life and good performance. Use while traveling long distances. High Perform — Provides best performance and good battery life. Use while on the road, traveling short distances. Custom — Set power management levels according to your own needs and pres- ent environment. Off — Office environment, using AC power. See the online documentation in the Windows NEC Information group for a lengthier dis- cussion of Power Management. See the following section for information on how using the special Save to File (STF) feature can benefit you. Using the Save to File (STF) Feature STF is a feature that protects the integrity of your working files. For example, if you get ur- gently called away from your NEC Versa without saving current data, your system auto- matically goes into Suspend mode. After 30 minutes pass, and you don’t return, your working environment is saved to a special file on your hard disk. There are two ways to set your NEC Versa’s STF feature. One method is via the Setup utility. Select Power Management from the Setup Main Menu. Move the cursor down and highlight Suspend Mode. Press the PgUp key and select STF. Save the settings and exit Setup. The second method is to press Fn Suspend simultaneously, before you leave your NEC Versa. This function initiates STF on demand., 2-32 Setup and Operation NOTE: When the status bar reads that there is only 4% power remaining in the system, the NEC Versa automatically performs a STF (if STF is enabled and functional). STF Benefits Using STF can benefit you in the following ways. When in STF, there is minimum battery drain. Preserves the life of the NEC Versa. Saves the user time. When the user returns from an urgent call or meeting, there is no need to reboot. AUTOMATIC POWER-SAVING FEATURES Table 2-9 lists the NEC Versa series automatic power conserving features. These features work during battery and AC operation. The features listed below do not work when the op- tional docking station is connected. The default timeouts listed below can be changed using Setup. Use the Fn F7 key combination to set the power management level. You can toggle be- tween Highest Performance, Longest Battery Life, Custom Power Management, Low, and Off. You can modify the custom level for your specific working environment using Custom. Default values change depending on the type of power management you use.

Are all cables and devices connected properly and securely? Are all needed device drivers installed properly? Have you checked the AUTOEXEC.BAT and CONFIG.SYS files for errors? Is the Suspend Mode activated on the LCD Status Bar? Press any key or press the power switch to power on the system.,

Section 4 Field Service Guidelines

This section contains preventive and corrective maintenance procedures for the NEC Versa 6000 Series notebook models as follows: NEC Versa 6050MH NEC Versa 6050MX. The first part of the section describes cleaning procedures and preferred handling proce- dures for sensitive components (for example disk drives, batteries). 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. NOTE: 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 all battery packs. 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 damp, almost dry cloth. Use glass cleaner to clean the LCD indicator panel. Apply the glass cleaner directly to the cloth and then wipe the LCD indicator panel. Do not use solvents or strong, abrasive cleaners on any part of the system., 4-2 Field Service Guidelines 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. 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 diskettes. Peri- odically use a head-cleaning diskette in the disk 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: Always back up the data files from the hard disk. Run a virus detecting program to check for possible virus infected areas on the hard disk. Use the preinstalled ScanDisk program to correct any errors found in the direc- tory and File Allocation Table (FAT). This will also free up space from any un- used sectors. Never turn the computer off when the hard disk is being accessed. Never 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. Acquire a hard disk maintenance program like DEFRAG under DOS, or Norton Utilities SPEEDISK programs. These programs reorganize your hard disk by eliminating 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: Do not drop the battery packs or subject them to excessive shock and vibration. Do not expose the battery packs to direct sunlight, moisture, or chemical com- pounds, or extreme heat. Do not disassemble the battery packs. Do not use the battery packs to power other devices. Do not short the battery leads or connect the battery with reversed polarity. Never attempt to charge the battery packs in any way other than as described in this manual and the User’s Guide. Always 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 corrective maintenance procedures can be performed using the following tools: Tweezers Small flat-head screwdriver Small Phillips screwdriver Small Hex-bolt screwdriver, 4-4 Field Service Guidelines DISASSEMBLY AND REASSEMBLY This subsection contains step-by-step disassembly procedures for the system.
