Identifying the Chassis, Routine Care, and Disassembly Preparation

5.4.2 Cleaning the Computer Case

Follow all safety precautions in Section 5.4.1, “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.

5.4.3 Cleaning the Keyboard

Follow all safety precautions in Section 5.4.1, “General Cleaning Safety Precautions,” before

cleaning the keyboard.

To clean the tops of the keys or the keyboard body, follow the procedures described in

Section 5.4.2, “Cleaning the Computer Case.”

When cleaning debris from under the keys, review all rules in Section 5.4.1, “General Cleaning

Safety Precautions,” before following these procedures:

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

the keys.

■ You may remove visible debris underneath or between the keys by vacuuming or shaking.

■ You may use canned, pressurized air to clean debris from under the keys. Use caution, 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.

CAUTION: Never remove a wide leveled key (like the space bar) from the keyboard. If these keys are

improperly removed or installed, the keyboard may not function properly.

■ Clean under a key with a swab moistened with isopropyl alcohol and squeezed out. Be

careful not to wipe away lubricants necessary for proper key functions. Use tweezers to

remove any fibers or dirt in confined areas. Allow the parts to air dry before reassembly.

5.4.4 Cleaning the Monitor

■ Wipe the monitor screen with a clean cloth moistened with water or with a towelette

designed for cleaning monitors. Do not use sprays or aerosols directly on the screen; the

liquid may seep into the housing and damage a component. Never use solvents or flammable

liquids on the monitor.

■ To clean the monitor body, follow the procedures in Section 5.4.2, “Cleaning the Computer

Case.”
