Section 4
Field Service Guidelines
This section contains preventive and corrective maintenance procedures for the NEC Versa
2400 Series notebook computers. The first part of this section will describe the computer
cleaning procedures and preferred handling procedures for sensitive components (i.e. disk
drives, batteries).
The second part of this section will identify all field replaceable parts plus the removal and
replacement procedures for these parts.

PREVENTIVE MAINTENANCE

Preventive maintenance is limited to cleaning the plastic case, the keyboard, the display
screen, and the floppy drive heads as required.

Cleaning the Notebook's Exterior

Use the steps described below to clean the outer surface of the system.
1. 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.
2.
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.
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, 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 still be present inside the system unit
and LCD even after the system has been turned
off.
