Computer, Keyboard, and Display
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.
• Use a can of compressed air to remove dust from between the keys on the keyboard and to remove any
dirt or lint from the display.
NOTICE: To help prevent damage to 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.
• Moisten a soft, lint-free cloth with either water or a display cleaner. Do not use alcohol or an ammonia-
based cleaner. Wipe the display gently working from the center to the edges until it is clean and any
fingerprints are removed. Do not use excessive pressure.
• 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 and turn off your computer. See "Turning Off Your Computer" on page 89.
2
Disconnect any attached devices from the computer and from their electrical outlets.
3
Remove any installed batteries. See "Using a Battery" on page 39.
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
NOTICE: Do not attempt to clean drive heads with a swab. You might accidentally misalign the heads which
prevents the drive from operating.
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
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.
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.
NOTICE: To help prevent damage to the surface, do not wipe in a circular motion around the disc.
