Routine care

General cleaning safety precautions

Never use solvents or flammable 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 airflow.

Cleaning the keyboard

CAUTION:
keys.
If the keyboard has an on/off switch, turn it off.
●
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:
improperly removed or installed, the keyboard might not function properly.
