The chip al- lows 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 pro- cedures. The N28F002BC-90 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 00F0000h-000FFFFFh. 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 1-17 VGA Controller The NeoMagic NM2160 is a PCI 128-bit Graphics Accelerator. The integrated program- mable linear address feature accelerates the graphics user interface (GUI) performance. The controller also supports Hardware Multimedia and VESA interface standards. The controller provides advanced power management that helps to minimize power usage in the following modes: normal operation Standby (sleep) mode panel off power saving modes. Parallel Interface The PC87338VJG 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 PC87338VJG chip operations include: ISA compatibility low-power CMOS with enhanced power-down mode Keyboard Controller The keyboard controller (H8/3434) supports a PS/2-style keyboard and, mouse. 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. PC CardBus Controller The Texas Instruments PCI1131 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., 1-18 Technical Information Sound Integrated Circuit The ESS Technologies chip set ES1869A provides dynamic audio circuitry with the fol- lowing: Audio digital processor Plug and Play support High-performance 16-bit Stereo Codec Full-duplex operation for simultaneous record and playback Analog joystick quad timer and digital joystick support. 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 priority.

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 ships with many power-saving features already enabled. See the following ta- ble. T able 1-5 Automatic Power-Saving Features Default Device Timeout Comment Idle ModeOnIdle mode slows down the CPU during brief periods when the system is not busy. Standby Timeout 4 minutes S pecifies how long the system is in Idle mode before entering Standby mode. Standby turns off various system devices including the screen. Auto Suspend 10 minutes T his setting specifies how long the system Timeout remains in Standby mode before entering Suspend. Hard Disk Timeout 2 minutes S tops the hard disk motor when the hard disk is not accessed for the specified timeout. Video Timeout 2 minutes S huts off video screen after the timeout specified elapses. CD-ROM Timeout45seconds S pecifies how long the CD-ROM reader remains inactive before being turned off.

NOTE

In Windows 95 systems, power management settings under Windows override the settings estab- lished in Setup. 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 you can toggle between Highest Performance, Longest Battery Life, Custom Power Management, and Off. Default values change depending on the type of power management you use., 1-20 Technical Information System Power Management NEC Versa system power management consists of the following operation modes. These modes are: Active Mode • In active mode, the system uses no power management. 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 battery power or AC. Standby mode shuts down the LCD panel, providing privacy as well as power savings. Suspend Mode • Suspend mode causes the CPU to 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, or the system is set to resume at a certain time of day. Suspend mode lets you save power without first saving the working data. Press the Fn-Esc keys simultaneously 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-Power Button buttons simultaneously. This shuts down the system, and saves the current working data to a file. Local Power Management Use Auto Setup to select one of four power management settings for local devices. These include Longest Life, Maximum Performance, Customize, and Power Management Off. The power management levels are also available during AC operation. The NEC Versa computer ships with Longest Life as the default power management setting. See Section 2 for specific procedures on using Auto Setup to select the power management settings. When set to Longest Life, CMOS will set local device timeout values, a local standby timeout value, and a suspend timeout value to ensure the longest battery life. The Maxi- mum Performance setting selects CMOS values that will provide minimal energy savings and a shorter battery life. The customize 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 man- agement timers., Technical Information 1-21 T able 1-6 Maximum Performance Default Settings Power Automatic Management Mode Suspend Hard Disk Timer Video Timeout Longest Life10minutes 2 minutes 2 minutes Maximum Performance30minutes 2 minutes 6 minutes C ustom10minutes 2 minutes 2 minutes PLUG AND PLAY The NEC Versa features Plug and Play functionality. 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 a monitor or device to the VersaBay, 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. The NEC Versa is capable of having a keyboard or mouse added or removed while in the Power On mode. This capability is known a Hot Swap. Changes made while in Suspend Mode are classified as a Warm Swap., 1-22 Technical Information

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 intended for use only with a NEC Versa 5000 Series 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 2-3 NEC Versa AC Adapter See the “Hardware Setup” earlier in this section for steps on connecting the AC adapter., Setup and Operation 2-5 Using the Main Battery Pack The NEC Versa comes with a rechargeable Lithium Ion (Li-Ion) battery pack. Battery power lasts for approximately one and half to three hours with power management features enabled. The battery pack is easy to install and remove. Checking Battery Power Levels Your NEC Versa 5000 Series system provides two tools to help you keep track of the main battery's power level: Battery Gauge utility, which lets you quickly identify how much battery power you have available. Windows 95 Battery Gauge, which lets you quickly identify how much battery power you have available. When remaining battery power falls to 10%, the system emits a single beep; when battery power falls to about 5%, the system beeps once every 60 seconds. When 3% battery power remains Save to File automatically initializes. 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 Fn-Esc keys simultaneously to put the system in Suspend mode, re- move the battery pack, and replace it with a fully charged Li-Ion battery. 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 3 hours. If you connect the system to AC power and do not use it, the battery recharges in about 3 hours. Customers can also buy an optional NEC Versa battery charger to quickly charge the bat- tery. See the online Versa Tools Catalog for more information. 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., 2-6 Setup and Operation

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 de- signed. 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. ! WARNING T here 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. Keep the battery away from heat sources including direct sunlight, open fires, microwave ovens, and high-voltage containers. Temperatures over 60ºC (140ºF) may cause damage. Do not drop or impact the battery. Do not disassemble the battery. Do not solder the battery. Do not puncture the battery. Do not use a battery that appears damaged or deformed, has any rust on its casing, is discolored, overheats, or emits a foul odor. Keep the battery dry and away from water. Keep metal objects away from battery terminals. Metal objects in contact with the terminals can cause a short circuit and damage. If the battery leaks onto skin or clothing, wash the area immediately. Battery fluid can cause a skin rash and damage fabric. If battery fluid gets in eyes, DO NOT rub; rinse with clear water immedi- ately and see a doctor. Make sure the battery is properly installed in the battery bay., Setup and Operation 2-7 Replacing the Battery Pack Replace the battery pack installed in your NEC Versa system as follows.

If the battery leaks: If the battery leaks onto skin or clothing, wash the area immediately with clean water. Battery fluid can cause a skin rash and damage fabric. If battery fluid gets into eyes, DO NOT rub; rinse with clear water immediately and consult a doctor. Take extra precautions to keep a leaking battery away from fire. There is a dan- ger of ignition or explosion. Recharging Battery Precautions Adhere to the following precautions when recharging the Li-Ion battery. Read the instructions that came with the battery charger before charging the bat- tery. Use only the NEC battery charger designed for your NEC Versa battery type. Different NEC Versa models require different batteries and battery chargers. Charge the battery for the specified charge time only. During charging, keep the environmental temperature between 32°F and 104°F (0°C to 40°C). Extending Battery Life While on the road, it is important to be aware of the simple things you can do to extend the life of the system’s main battery. One way is to keep the LCD backlight setting at the low- est. You can toggle between these four settings by pressing the function keys, Fn - F5., 2-12 Setup and Operation OPERATING CONTROLS The following section describes system controls, the LEDs, and function keys. Power Button and Status LEDs Y our NEC Versa provides a Power button and LEDs to track system status. Descriptions of these features follow the figure. F igure 2-9 Power button and Status LED location Power Button — The Power button is located on the chassis just below the LCD. It turns NEC Versa 5000 power on and off. Press the button to turn power on; press it again to turn power off. When power is on, the Power LED to the right of the Power button lights. (The Power LED is the left-most LED in the row of LEDs.) See “Setup Parameters” in later in this section for information about defining this button as a Suspend/Resume button. I f your system is in Suspend mode or has gone into Save to Disk mode, pressing the Power button puts the system in Operation mode., Setup and Operation 2-13

NOTE

After turning off the system, wait 5 seconds before turning it back on. This gives system compo- nents a chance to power down properly. The Battery/Charging Status LED is located on the right-hand LCD hinge and lights to indicate the following: Green – the battery is fully charged and the system is connected to AC power. Amber – the battery is recharging. Off – the AC adapter is disconnected or the battery is not installed. A bank of status LEDs is located on the chassis at the top of the keyboard to the right of the Power button. These LEDs are identified by icons and include the following (described from left to right): The Power LED lights in the following sequence to indicate system opera- tion status. – lights green when running on AC power. – blinks green when the system is in Suspend mode. – lights amber when running on battery power with a charged battery. T he Power LED also warns you about a low battery state. The system emits a beep and the Power LED behaves as follows: – blinks amber when battery power is low. – flashes amber when battery power is extremely low. The Power LED remains unlit under the following conditions: – if the system is not connected to AC power and the battery is not charged or installed. – the system is not powered on. – the system is in Save to Disk mode., 2-14 Setup and Operation Hard Disk Drive – Lights when the NEC Versa 5000 writes data to or re- trieves data from the hard disk drive. CD-ROM Reader – Lights when data is read from a compact disc in the CD- ROM drive. Diskette Drive – Lights when data is written to or retrieved from the 3.5-inch diskette drive. Caps Lock – Lights when Caps Lock is on. Num Lock – Lights when Num Lock mode is active. Scroll Lock – Lights when the Scroll Lock is on. Function Keys (Fn Keys) Function keys set specific system parameters and are built into the ROM. When using these keys, simultaneously press Fn and the corresponding function key. See Table 2-3 for a list of ROM-based hot keys. ROM-based hot keys change system parameters temporar- ily. Hot Key functions operate until the system is turned off or reset. Table 2-3 Function Keys Key Combination Function F n-Esc I nitiates Suspend mode. F n- Power Button I nitiates a Suspend to Disk. F n-F2 T oggles character highlighting on and off (DOS display only). F n-F3 T oggles the display between three video modes, LCD, CRT, or simultaneous display on both. Fn-F5 A djusts the LCD panel brightness. Fn-F6 S ets the internal system speaker volume to on or off. Fn-F7 T oggles between various power management levels (Off, Custom, Highest Performance, and Longest Life.) F n-F12 S ets Scroll Lock on or off. NumLock T oggles Num Lock on and off activating and deactivating the embedded numeric keypad. F n-LeftCtrl S imulates the right Ctrl key., Setup and Operation 2-15 Other key combinations — the following key combinations are available with some applications: Fn-Prt Scr — sends a system request (SysReq) used in some terminal emulation applications. Fn-Pause — sends a break (Break) command in some applications. Windows 95 keys — You can use the following two key combinations to facilitate your work: Shortcut/Application key – provides quick access to shortcut menus. (This key acts like a right mouse button.) Floating Window key – displays the Start menu. Cursor Control keys — Cursor control keys let you position the cursor on the screen where you want. On the screen, the cursor is a blinking underline, block, or vertical bar depending on the application. The cursor indicates where the next typed character will be inserted. Typewriter keys — The typewriter keys (also called alphanumeric keys) are used to enter text. Keys with blue printing on them behave differently when combined with Fn. Numeric Keypad — Pressing NumLock on the keyboard activates the numeric keypad numbers and functions printed in blue on top of these keys. T he keypad lets you type numbers, a decimal point and mathematical operands (+, –, *, /) as you would on a calculator. The keypad is ideal for entering long lists of numbers. T o use the numeric keypad, press NumLock. When you press NumLock again, the keys revert to their normal functions as typewriter keys. Holding the Fn key down while pressing cursor control keys on the nu- meric keypad makes the keys function as control keys. Control keys — Ctrl, Alt, Fn, and Shift are controls used in conjunction with other keys to change their functions. To use control keys, press and hold the control key while pressing another key. For example, “press Ctrl c” means to hold down the Ctrl key and type the letter c. How the key combination works depends on the applications you are running. Smart Power Switch The Smart Power switch provides an automatic feature that prevents you from accidentally powering off the NEC Versa, and losing your data while your system is in Suspend mode. The Smart Power switch senses that the system is in Suspend mode and prevents you from directly powering off the system when you press the Power button., 2-16 Setup and Operation To power off the system from Suspend mode, 1. press the Suspend/Resume button to make the system active. 2. press the Power button to turn off the system. POWER-ON SELF-TEST (POST) Each time the system is powered on, the system checks the working status of components through an automatic power-on self-test (POST). The test checks the system configuration for any discrepancies. One beep means that POST is successful. If any problems in data transfer or hardware exist, an error message appears. If the message is an Invalid Configuration message, press F2 to enter the Setup utility. The system collects Setup data and lists the changes detected in the current parameter settings, that can be seen in Standard CMOS Setup. Press Enter to review the settings, and make any necessary corrections. If no error messages appear but the system still malfunctions, check the items in the list below. The Power button for each peripheral is on. All cables and power cords are tightly connected. The electrical outlet is working. All options have been properly installed.

Section 4 Field Service Guidelines

This section contains preventive and corrective maintenance procedures for the following NEC Versa 5000 Series models: NEC Versa 5060 NEC Versa 5060X. Section 4 is broken into four sections, which are presented in the following order: “Preventive Maintenance” describes cleaning procedures and preferred handling procedures for sensitive components (for example disk drives, batteries). “Disassembly and Assembly” identifies all field replaceable parts with the remain- der of the section containing the removal and replacement procedures for the field replaceable parts. “Illustrated Parts Breakdown” contains an exploded view diagram and a listing of field-replaceable parts with part numbers. “Service and Product Information” lists NEC service and information telephone numbers. PREVENTIVE MAINTENANCE Preventive maintenance is limited to cleaning the plastic case, the keyboard, the display screen, and 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 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., 4-2 Field Service Guidelines 2. Wipe the outside of the system, keyboard, and display with a soft, clean cloth. Remove stains with a damp, almost dry cloth. Use glass cleaner to clean the LCD. Apply the glass cleaner directly to the cloth and then wipe the LCD. 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. Cleaning the Notebook 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, particularly 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 also frees up space from any unused 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. Be especially careful not to jar the hard disk during access; this can cause a hard disk crash., Field Service Guidelines 4-3 Use hard disk maintenance program like DEFRAG under DOS, or acquire Norton Utilities SPEEDISK programs. These programs reorganize your hard disk by eliminating fragmentation and improves the hard disk access time. Handling the Battery Pack The battery pack 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 pack endures for a normal life cycle, always observe the follow- ing precautions 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, 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. DISASSEMBLY AND REASSEMBLY This section contains step-by-step disassembly procedures for the system. Reassembly is the reverse of disassembly. Each procedure is supported by a simplified disassembly illustration to facilitate removal. The Illustrated Parts Breakdown and parts lists for the system unit are shown later. For complete disassembly of the system, follow the disassembly order listed in Table 4-1.
