Cleaning the computer components
Because many of the computer components consist of sophisticated integrated 
circuit boards, it is very important to periodically clean the computer to prevent 
dust buildup. The cleaning supplies you need to clean the components include: 
a vacuum cleaner, a soft cotton cloth, clear water (preferably purified or distilled 
water) 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 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 the computer.

LCD monitors should be cleaned daily. Use a dry cloth to brush dust from the 
monitor and keyboard every day. Keep all surfaces clean and free of grease stains.
