Chapter 5: Maintaining Your Computer
Cleaning your computer
Keeping your computer clean and the vents free from dust helps keep your computer
performing at its best. You may want to gather these items and put together a computer
cleaning kit:
■ A soft, lint-free cloth
■ An aerosol can of air that has a narrow, straw-like extension
■ Cotton swabs
■ A CD or DVD drive cleaning kit
Cleaning the exterior
Always turn off your computer and other peripherals before cleaning any components.
Use a damp, lint-free cloth to clean your computer and other parts of your system. Do
not use abrasive or solvent cleaners because they can damage the finish on components.
Your computer is cooled by air circulated through the vents on the case, so keep the vents
free of dust. With your computer turned off and unplugged, brush the dust away from
the vents with a damp cloth. Be careful not to drip any water into the vents. Do not attempt
to clean dust from the inside of your computer.
Cleaning the keyboard
You should clean the keyboard occasionally by using an aerosol can of air with a narrow,
straw-like extension to remove dust and lint trapped under the keys.
If you spill liquid on the keyboard, turn off your computer and turn the keyboard upside
down. Let the liquid drain, then let the keyboard dry before trying to use it again. If the
keyboard does not work after it dries, you may need to replace it.
Cleaning the monitor
Warning
When you shut down your computer, the power turns off, but some
electrical current still flows through your computer. To avoid possible
injury from electrical shock, unplug the power cord and modem cable
from the wall outlets.
Caution
A flat panel display or LCD screen is made of specially coated glass
and can be scratched or damaged by abrasive or ammonia-based
glass cleaners.
