FIC MD02 Service Manual 5-1

Chapter

5.1 Introduction

This section contains preventive and corrective maintenance procedures for the MD02

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 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.
