General Maintenance

If you need to clean the computer or display beyond wiping them down with a clean cloth, follow these instructions:

1Turn your computer and display off.

2Disconnect the computer power cable from the electrical outlet or power strip. If your display has a power cable connected to an outlet, disconnect it as well.

3Disconnect the display’s cables from the computer.

4Clean the display screen with soft, lint-free paper or cloth dampened with mild soap and water.

Warning Do not spray liquid directly onto the display screen. Liquid could drip inside the display and cause electrical shock.

5Wipe the computer or display case surfaces lightly with a clean, soft cloth dampened with water.

Don’t use alcohol, aerosol sprays, solvents, or abrasives that might damage the ﬁnish on the case.

Protecting Your CD or DVD Drive

To keep your CD or DVD drive working properly:

mPosition your computer so that the drive tray doesn’t bump into anything when it opens.

mClose the drive when you’re not using it.

mDo not put anything on the drive tray when it is open.

mDo not touch the lens with your ﬁngers. Do not wipe the lens with a paper towel or other abrasive surface. If you need to clean the lens, see an Apple-authorized service provider for a lens cleaner.

mKeep your computer away from any source of moisture.
