8.Wipe the surface again with a dry, soft, lint-free cloth.

9.Wait for the surface to dry completely and remove any fibers from the cloth.

Note: Shut down the computer and then disconnect the power cord before cleaning the computer.

Cleaning your computer keyboard

To clean the computer keyboard, do the following:

1.Apply some isopropyl rubbing alcohol to a soft, dust-free cloth.

2.Wipe each keytop surface with the cloth. Wipe the keys one by one; if you wipe several keys at a time, the cloth might hook onto an adjacent key and possibly damage it. Make sure that no liquid drips onto or between the keys.

3.Allow to dry.

4.To remove any crumbs and dust from beneath the keys, you can use a camera blower with a brush or cool air from a hair drier.

Note: Avoid spraying cleaner directly onto the display or the keyboard.

Cleaning your computer display

To clean your computer display, do the following:

1.Gently wipe the display with a dry, soft, lint-free cloth. If you see a scratchlike mark on your display, it might be a stain transferred from the keyboard when the cover was pressed from the outside.

2.Wipe or dust the stain gently with a soft, dry cloth.

3.If the stain remains, moisten a soft, lint-free cloth with water or a 50-50 mixture of isopropyl alcohol and water that does not contain impurities.

4.Wring out as much of the liquid as you can.

5.Wipe the display again; do not let any liquid drip into the computer.

6.Be sure to dry the display before closing it.
