Maintenance and Disassembly

Preventive Maintenance
Preventive maintenance is limited to cleaning the plastic case, the keyboard, the
display screen and cleaning the floppy drive heads as required.
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.
NOTE: 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 is 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 finish.
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 diskette drive
to prolong the life of the drive and to help maintain data integrity.
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 down the machine and close the cover. But
the display surface - no matter what type it is - and the components inside the
computer radiate 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.
Maintaining the Hard Disk Drive
The hard disk drive is one of the most common parts that which can pose a
problem. Here are some preventive maintenance tips to follow when handling
the hard disk.
n
Always back up the data files from the hard disk.
n
Run a virus detection program for possible virus-infected areas on the
hard disk.
n
Use SCANDISK to correct any errors found in the directory and File
Allocation Table (FAT). This also frees up space from any unused
sectors.
n
Never turn the computer off when the hard disk is accessed.
