5.3 Routine Care
5.3.1 General Cleaning Safety Precautions
1. Never use solvents or flammable solutions to clean the computer.
2. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth
and then use the cloth on the component.
3. Always unplug the computer when cleaning with liquids or damp cloths.
4. Always unplug the computer before cleaning the keyboard, mouse, or air vents.
5. Disconnect the keyboard before cleaning it.
6. Wear safety glasses equipped with side shields when cleaning the keyboard.
5.3.2 Cleaning the Computer Case
Follow all safety precautions in Section 5.3.1, “General Cleaning Safety Precautions,” before
cleaning the computer.
To clean the computer case, follow the procedures described below:
■
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.
