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 workstation 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 dish washing liquid diluted with water. Rinse well by wiping it 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.
