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.

Cleaning the Notebook's Exterior

Use the steps below to clean the outer surface of the system.
Power off the system and remove the primary battery pack. Unplug all cables
1.
connected to the system.
Wipe the outside of the system unit, keyboard, and display with a soft, clean cloth.
2.
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.
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.
