Appendix B. Use and care information

 Cleaning your computer keyboard

Absorb some isopropyl rubbing alcohol on a soft, dust-free cloth.

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.

Allow to dry.

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.
