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.

Cleaning the computer case

Follow all safety precautions in General cleaning safety precautions on page 11 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.

Cleaning the keyboard

Follow all safety precautions in General cleaning safety precautions on page 11 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 11.

When cleaning debris from under the keys, review all rules in General cleaning safety precautions on page 11 before following these procedures:

CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the keys.

●Visible debris underneath or between the keys may be removed by vacuuming or shaking.

●Canned, pressurized air may be used to clean debris from under the keys. Caution should be used as too much air pressure can dislodge lubricants applied under the wide keys.

●If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool is available through many electronic supply outlets.
