Cleaning your computer keyboard

1 Absorb some isopropyl rubbing alcohol on 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 may 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 on the display or the keyboard.

Cleaning your computer display

1Gently 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.

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

3If 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.

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

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

6Be sure to dry the display before closing it.
