Cleaning your computer

Use the following products to safely clean your computer:

Dimethyl benzyl ammonium chloride 0.3 percent maximum concentration (for example,

disposable wipes, which come in a variety of brands)

Alcohol-free glass-cleaning fluid

Water with mild soap solution

Dry microfiber cleaning cloth or a chamois (static-free cloth without oil)

Static-free cloth wipes

CAUTION:

Avoid strong cleaning solvents that can permanently damage your computer. If you are

not sure that a cleaning product is safe for your computer, check the product contents to make sure

that ingredients such as alcohol, acetone, ammonium chloride, methylene chloride, and hydrocarbons

are not included in the product.
Fibrous materials, such as paper towels, can scratch the computer. Over time, dirt particles and

cleaning agents can get trapped in the scratches.

Cleaning procedures

Follow the procedures in this section to safely clean your computer.

WARNING!

To prevent electric shock or damage to components, do not attempt to clean your

computer while it is turned on.

Turn off the computer.

Disconnect AC power.

Disconnect all powered external devices.

CAUTION:

To prevent damage to internal components, do not spray cleaning agents or liquids

directly on any computer surface. Liquids dripped on the surface can permanently damage internal

components.

Cleaning the display

CAUTION:

Do not spray or place the cleaner directly on the screen.

Gently wipe the sides and the surface of the display using a soft, lint-free cloth moistened with an

alcohol-free glass cleaner.

Cleaning the computer vents

Air vents keep the computer cool. Keep these vents clean by using a small, battery-powered vacuum

cleaner. (A battery-powered vacuum cleaner eliminates the risk of electric shock.)

1.

Vacuum the vents on the computer case.

2.

Remove any debris that has accumulated in and around the computer connectors (for example,

the Ethernet and USB connectors).
