Appendix B. Use and care information

Cleaning the cover of your computer

Occasionally clean your computer as follows:

1 Prepare a mixture of a gentle kitchen-use detergent (one that does not contain abrasive powder or strong chemicals such as acid or alkaline). Use 5 parts water to 1 part detergent.

2Absorb the diluted detergent into a sponge.

3Squeeze excess liquid from the sponge.

4Wipe the cover with the sponge, using a circular motion and taking care not to let any excess liquid drip.

5Wipe the surface to remove the detergent.

6Rinse the sponge with clean running water.

7Wipe the cover with the clean sponge.

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

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

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

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

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.

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.
