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:
