3.1 Routine Care

3.1.1 Cleaning Safety Precautions

! Never use solvents or flammable solutions to clean the computer.

Never immerse any parts in water or cleaning solutions; apply any liquids to a

clean cloth and then use the cloth on the component.

! Always turn off the computer when cleaning with liquids or damp cloths.

Always turn off the computer before cleaning the keyboard, mouse, or air vents.

! Disconnect the keyboard before cleaning it.

! Wear safety glasses equipped with side shields when cleaning the keyboard.

3.1.2 Cleaning the Computer Case

Follow all safety precautions in Section 3.1.1 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 it with a cloth or swab dampened with clear water.

! For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed as the

alcohol will evaporate quickly and not leave a residue.

After cleaning, always wipe the unit 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.
