Maintenance & Disassembly

5.1 Introduction
This section contains preventive and corrective maintenance procedures for the M785
notebook. The first part of the section describes the computer cleaning procedures and
preferred handling procedures for sensitive components (e.g. disk drives, LCD, CPU,
batteries).

The second part of the chapter identifies all field replaceable parts with the remainder
explaining the removal and replacement procedures for the field replaceable parts.

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

5.2.1 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.

i Never use alcohol, petroleum-based solvents, or harsh detergents to clean the
notebook. Also, do not 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 by first applying a mild glass cleaner to a
soft, clean, lint-free cloth, and gently wipe the glass. Never apply liquids directly
on the screen surface. Moreover, do not use paper towels to clean the display
screen. Paper can scratch the display screen matte.


5.2.2 Protecting the Disk Drives
To protect the disk drives and data, back up the system disk periodically on floppy diskettes.
Periodically use a head-cleaning diskette in the floppy diskette drive to prolong the life of the
drive and to help maintain data integrity.

5.2.3 Maintaining the LCD Quality
When it comes to screen problems, heat plays a big part. After a good working session, the
typical routine is to shut the machine and close the cover. But the display surface - no matter
what type it is - and the components inside the computer radiates heat; when you close the
cover, you trap the heat against the screen. Leave the computer's cover open for about ten
minutes while the heat disperses. Make this a habit.
