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:
