8.2 Cleaning Your 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 co mputer cleaning kit.
Never use alcohol, petroleum-based solvents, or harsh detergents to clean the
notebook. Also 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 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.
