System Power Management

NEC Versa system power management consists of the following operat ion modes. These modes are:

Active Mode  In active mode, the system uses no power management. It oper-



ates 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 co nsumption when yo u operate the system on battery power or AC. Standby mode shuts down the LCD panel, pr oviding privacy as well as po wer savings.

Suspend Mode  Suspend mode causes the CPU to po wer down, local devices



to shut down, and register values to be stored in RAM. System RAM is put into a slow refresh state. A half mo on icon in the LCD Status Bar indicates that Suspend mo de is in e ffec t.

Technical Information 1-23

The system resumes Active mod e when you press the Suspend button, or the sys tem is set to r esume at a certa in t ime of d ay. Suspen d mode le ts yo u save power without first saving the working data.

Press the Suspend button to enter S uspend mode when you need to be away from the system for a short period of time and want to r eturn to where you left off.

In addition, to quickly activate the Save to File feature, press the Fn and Suspend buttons simultaneously. This shuts down the system, and saves the current wor k ing da ta to a file.

Local Power Management

Use Auto Setup to select one of four power management sett ings for local devices. T hese include Longest Off. The power management levels are also available during AC oper ation. The NEC Versa computer ships with Longest Section 2 for specific procedures on using Auto Setup to select the power management settings.

Section 4

Field Service Guidelines

This section contains preventive and cor r ective maintenance procedures for the NEC Versa 6220/30/60 notebook computers.

The first part of the section describes cleaning procedures and preferred handling procedures for sensitive components (for example disk drives, batteries).

The second part of the section identifies all field replaceable parts with the remainder o f the section containing t he removal and replacement pro cedur es for the field replaceable parts.

PREVENTIVE MAINTENANCE

Pre v entive ma in tenanc e is limited to cleaning the pla stic case, the keyboa rd, and the displa y 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.

Power off the system and remo ve all battery packs. Unplug all cables connected to the system.

Wipe the outside of the system unit, keyboard, and display with a soft, clean cloth. Remove stains with a damp, almost dry cloth. Use liquid glass cleaner to clean the LCD indicato r panel. Apply t he glass cleaner directly to t he cloth and then wipe the LCD indicat or panel. Do not use solvents or strong, abrasive cleaners on any part of the system.

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 plat e, possibly damaging the components under the keys. If the keyboard gets wet , thoroughly dry it before reassembling the system unit.

Cleaning the Notebook’s Interior

Whe n serv icing the inside of the noteb ook, re mov e dust and o th er fore ign particles from inside the system unit as follows.

Remove the top cover and keyboard using t he disassembly procedures discussed late r in th is section .

Dust or vacuum (with a rubber-tipped nozzle) the inside of the system unit par ticularly the motherboard surface. Use care t o avoid damaging or dislodging any components or cables.

Inspect all cables connecto r s for damage. Ensure t hat connectors are seated properly before replacing the cover.

Protecting the Disk Drives

To protect the disk drives and data, back up t he system disk perio d ically on diskettes. Occasionally use a head-cleaning diskette in the disk drive to pro long the life o f the drive and t o h elp mainta in data in tegrity.

Here are some maint enance 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 po ssible virus infected areas on the

hard disk.



Use the preinstalled ScanDisk program to cor r ect any errors found in the direc-

t ory and F ile Alloc ation T able (FAT). This will a lso free up space from any unused sector s.



Never turn the computer o ff when the hard disk is being accessed.



Never move or raise the computer while t he hard disk is being accessed, most es-

pecially don't jar the hard disk as this may cause a hard disk crash.



Acquir e a hard disk maintenance program like DE FRAG under DOS, or Norto n

Utilitie s S PEEDISK pro grams. These p rog ra ms r eor ganize your hard d isk b y eliminating fragmentation and improves the ha rd disk access time.

Handling the Battery Packs

The battery packs furnished with the computer require reasonable care and handling to ensure efficient operation and maximum life. Periodically inspect the battery terminals and the batteries for evidence of corrosion and oxide build- up.

To ensure t hat the battery packs endure normal life cycle, always observe the following precautions when handling the battery packs:

Do not dr op the batt er y packs or subject them to excessive shock and vibrat ion.



Do not expo se the battery packs to direct sunlight, moisture, or chemical co m-



pounds, or ext r eme heat. Do not disassemble the battery packs.



Do not use the battery packs to power other devices.

Field Service Guidelines 4-3

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 batt er y packs as soo n as po ssible after a low batter y indication.

Maintaining the LCD Quality

When it comes to screen pro blems, heat plays a big part. After a good working session, the typical ro utine is t o 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 co r r ective maintenance procedures can be performed using the following tools:



Tweezers



Small flat-head screwdriver



Small Phillips screw dr iver



Small Hex-bolt s c rewdriver
