6.1 Introduction
This section contains general preventive and corrective maintenance procedures that
apply to all members of the Extensa 900 Notebook family. The first part of the section
describes the computer cleaning procedures and preferred handling procedures for
sensitive components (e.g., disk drives, batteries).
The second part of the section identifies all field-replaceable parts; the remainder of the
section contains removal and replacement procedures for the field-replaceable parts.
6.2 Preventive Maintenance
Preventive maintenance is limited to cleaning the plastic case, keyboard and the display
screen.
6.2.1 Cleaning the Computer
When it is necessary to clean the plastic case and keyboard use a soft, lint-free cloth,
slightly dampened with a mild detergent solution or use the contents of any
commercially available computer cleaning kit.
Caution: Never spray any liquids directly on the computer case, keyboard,
or screen. If the liquid-crystal display (LCD) screen has become smeared
or dusty, clean the screen first with a soft, clean, lint-free cloth and gently
wipe the glass. If the glass is still smeared, use distilled water or a 25%
solution of alcohol and distilled water.
Caution: Do not use paper towels to clean the display screen. Paper can
scratch the display screen matte.
