4.6 Performing Daily Maintenance Tasks

Cleaning the computer components

Because many of the computer components consist of sophisticated integrated

circuit boards, it is very important to periodically clean around the computer

to prevent dust buildup. The cleaning supplies you need in order to clean the

components include: a vacuum cleaner, a soft cotton cloth, clear water (pure water

preferred) and cotton swabs.

Attention: Before you clean your computer, disconnect the computer

from the electrical outlet. Clean your computer with a soft cloth

dampened with water. Do not use liquid or aerosol cleaners, which may

contain flammable substances.

Note: To avoid damaging the computer or display, do not spray cleaning

solution directly onto the display. Only use products specifically designed

for cleaning displays, and follow the instructions that are included with the

product.

The following are general methods for cleaning the components:

• You can use a soft cloth to remove dust on the surface of the computer, the

monitor, the printer, the speakers and the mouse.

• You can use a vacuum cleaner to clean in otherwise inaccessible corners.

• To clean the keyboard thoroughly, shut down the computer and scrub it gently

with a wet cloth.

• Do not use the keyboard until it is dry.

Do not do any of the following:

• Allow water to enter the computer

• Use a heavily dampened cloth

• Spray water directly onto the surface of the monitor or inside of computer.

Daily attention should be given to LCD monitors. Use a dry cloth daily to brush

dust from the monitor and keyboard. Keep all surfaces clean and free of grease

stains.
