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
• An optical disc drive cleaning kit
Cleaning the exterior
• Always turn off your computer and other peripheral
devices before cleaning any components.
• Use a damp, lint-free cloth to clean your computer and
other parts of your system. Do not use household
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.
Cleaning the keyboard
You should occasionally clean the keyboard to remove dust and
lint trapped under the keys.
To clean the keyboard:
1 Use an aerosol can of air with a narrow, straw-like
extension to remove dust and lint trapped under the
keys.
Warning
When you shut down your computer, the power turns off, but some
electrical current still flows through it. To avoid possible injury from electrical
shock, unplug the power cord, modem cable, and network cable from the wall
outlets.
