Cleaning Your Computer



Computer, Keyboard, and Display



lUse a can of compressed air to remove dust from between the keys on the keyboard.

lMoisten a soft, lint-free cloth with either water or a display cleaner, and wipe the display until it is clean.

lMoisten a soft, lint-free cloth with water and wipe the computer and keyboard. Do not allow water from the cloth to seep between the touch pad and

the surrounding palm rest.



Touch Pad



1. Shut down your computer.



2. Disconnect any attached devices from the computer and from their electrical outlets.



3. Remove any installed batteries. See Replacing the Battery.



4. Moisten a soft, lint-free cloth with water, and wipe it gently across the surface of the touch pad. Do not allow water from the cloth to seep between the

touch pad and the surrounding palm rest.



Floppy Drive

Clean your floppy drive using a commercially available cleaning kit. These kits contain pretreated floppies to remove contaminants that accumulate during

normal operation.



CDs and DVDs

If you notice problems, such as skipping, with the playback quality of your CDs or DVDs, try cleaning the discs.



1. Hold the disc by its outer edge. You can also touch the inside edge of the center hole.



2. With a soft, lint-free cloth, gently wipe the bottom of the disc (the unlabeled side) in a straight line from the center to the outer edge of the disc.

For stubborn dirt, try using water or a diluted solution of water and mild soap. You can also purchase commercial products that clean discs and provide

some protection from dust, fingerprints, and scratches. Cleaning products for CDs are also safe to use on DVDs.

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

CAUTION: Before you clean your computer, disconnect the computer from the electrical outlet and remove any installed batteries. Clean your

computer with a soft cloth dampened with water. Do not use liquid or aerosol cleaners, which may contain flammable substances.

NOTICE: To avoid damaging the computer or display, do not spray cleaning solution directly onto the display. Only use products specifically designed for

cleaning displays, and follow the instructions that are included with the product.

NOTICE: Do not attempt to clean drive heads with a swab. You might accidentally misalign the heads which prevents the drive from operating.

NOTICE: Always use compressed air to clean the lens in the CD/DVD drive, and follow the instructions that come with the compressed-air product.

Never touch the lens in the drive.

NOTICE: To avoid damaging the surface, do not wipe in a circular motion around the disc.
