9 Routine care
General cleaning safety precautions
● Never use solvents or ammable solutions to clean the computer.
● Never immerse any component in water or cleaning solutions; apply any liquids to a clean cloth and then
use the cloth on the component.
● Always unplug the computer before cleaning the keyboard, mouse, or air vents.
● Always disconnect the keyboard before cleaning it.
● Wear safety glasses equipped with side shields when cleaning the keyboard.
Cleaning the chassis
● Follow the safety precautions in the Maintenance and Service Guide for your computer before cleaning
the computer.
● To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.
● For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping the computer
with a cloth or swab dampened with clear water.
● For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is required because the alcohol
evaporates quickly and does not leave a residue.
● After cleaning, always wipe the computer with a clean, lint-free cloth.
● Occasionally, clean the air vents on the computer. Lint and other foreign matter can block the vents and
limit the airow.
Cleaning the keyboard
CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the
keys.
● If the keyboard has an on/o switch, turn it o.
● Follow the safety precautions in the Maintenance and Service Guide for your computer before cleaning
the computer.
● Visible debris underneath or between the keys can be removed by vacuuming or shaking.
● Canned, pressurized air can be used to clean debris from under the keys. Use caution because too much
air pressure can dislodge lubricants applied under the wide keys.
● To remove a key, use a specially designed key remover to prevent damage to the keys. This tool is
available from many electronics supply outlets.
CAUTION: Never remove a wide key (like the space bar key) from the keyboard. If these keys are
improperly removed or installed, the keyboard might not function properly.
