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 cloth

■Window cleaner (not for use on LCD panels)

■An aerosol can of air that has a narrow, straw-like extension

■Isopropyl alcohol

■Cotton swabs

■A CD/DVD drive cleaning kit

Cleaning the exterior

Warning When you shut down your computer, the power turns off, but some electrical current still flows through the computer. To avoid possible injury from electrical shock, unplug the power cord and modem cable from the wall outlets.

Always turn off the computer and other peripherals before cleaning any components.

Use a damp, lint-free cloth to clean the 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 the 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 the computer.
