Field Service Guidelines

This section contains preventive and corrective maintenance procedures for the NEC Versa

2500 Series notebook computers. The first part of this section describes the computer

cleaning procedures and preferred handling procedures for sensitive components (i.e., disk

drives, batteries).

The second part of this section identifies all field replaceable parts plus the removal and re-

placement procedures for these parts.

Preventive maintenance is limited to cleaning the plastic case, the keyboard, the display

screen, and the diskette drive heads as required.

Use the steps described below to clean the outer surface of the system.

Power off the system, remove the primary battery pack, and unplug all cables

connected to the system.

Wipe the outside of the system unit, keyboard, and display with a soft, clean cloth.

Remove any stains with water only. Use glass cleaner to clean the LCD indicator

panel. Apply the glass cleaner directly to the cloth and then wipe the LCD indica-

tor panel. Do not use solvents or strong, abrasive cleaners on any part of the sys-

tem.

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, this could possibly dam-

age the components under the keys. If the keyboard gets wet, thoroughly dry it

before reassembling the system unit.

NOTE: Remove the battery and disconnect the

AC adapter before performing any maintenance.

Voltage will be present inside the system unit and

LCD even after the system has been turned off.
