Cleaning your computer
Keeping your computer clean and the vents free from dust helps keep your
system 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
■ Isopropyl alcohol
■ Cotton swabs
■ A CD or DVD drive cleaning kit
Cleaning the exterior
Always turn off your computer and other peripherals, then remove the main
and optional secondary batteries 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 your
computer.
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.
