Maintaining Your Computer
Cleaning Components
Internal fans cool the computer by drawing in air through air vents in the front of the
computer and blowing it out the rear-side panels. Dust and other debris is drawn in
with the air and, if allowed to build up, will interfere with the operation of various
system components and insulate components, preventing heat from dissipating. To
prevent this, an air filter has been installed in front of the air vents in the front panel
to block dust and other debris from entering the computer.
Dust and debris builds up on the air filter over time. When the air filter becomes very
dirty, it is difficult for cooling air to pass through the air filter and enter the computer.
So, the air filter must be cleaned to prevent the computer from overheating. Remove
and clean the air filter on a regular basis following the steps described in the “Air
Filter” section of Chapter 2. Also, regularly vacuum the exterior of the chassis to
remove dust that has accumulated around the air vents.
