Use this information to properly care for your computer.
General cleaning safety precautions
Use this information to safely clean your computer.
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.
Cleaning the computer case
Follow all safety precautions before cleaning the computer case.
To clean the computer case, follow these procedures:
●
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 because the alcohol evaporates
quickly and does 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.
Cleaning the keyboard
Use this information to properly clean the keyboard. Follow all safety precautions before cleaning the keyboard.
To clean the tops of the keys or the keyboard body, follow the procedures described in Cleaning the computer
case on page 16 .
When cleaning debris from under the keys, review all rules in General cleaning safety precautions on page 16
before following these procedures.
CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the
keys.
●
You can remove visible debris underneath or between the keys by vacuuming or shaking.
●
You can use canned, pressurized air to clean debris from under the keys. Use caution because too much air
pressure can dislodge lubricants applied under the wide keys.
