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.
2
Absorb the diluted detergent into a sponge.
3
Squeeze excess liquid from the sponge.
4
Wipe the cover with the sponge, using a circular motion and taking care not to let any
excess liquid drip.
5
Wipe the surface to remove the detergent.
6
Rinse the sponge with clean running water.
7
Wipe the cover with the clean sponge.
8
Wipe the surface again with a dry, soft lint-free cloth.
9
Wait for the surface to dry completely and remove any cloth fibers from the computer
surface.
„ 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.
„
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.
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.
Note:
Shut down the computer and then disconnect the power cord before cleaning the computer.
Note:
Avoid spraying cleaner directly on the display or the keyboard.
