• If possible, place your computer in a well-ventilated and dry area without direct exposure to sunshine.

• Keep your computer away from magnets, activated cellular phones, electrical appliances, or speakers (more than 13 cm or 5 inches).

• Avoid subjecting your computer to extreme temperatures (below 5°C/41°F or above 35°C/95°F).

• Avoid placing any objects (including paper) between the display and the keyboard or the palm rest.

• Do not turn your computer over when the ac power adapter is plugged in, otherwise, it could break the adapter plug.

• Before moving your computer, be sure to remove any media, turn off attached devices, and disconnect cords and cables.

• When picking up your open computer, hold it by the bottom. Do not pick up or hold your computer by the display.

• Avoid directly exposing your computer and peripherals to the air from an appliance that can produce negative ions. Wherever possible, ground your computer to facilitate safe electrostatic discharge.

Cleaning the computer cover: Wipe it with a lint-free cloth dampened in mild soap and water. Avoid applying liquids directly to the cover.

Cleaning the keyboard: Wipe the keys one by one with a lint-free cloth dampened in mild soap and water. If you wipe several keys at a time, the cloth might hook onto an adjacent key and possibly damage it. Avoid spraying cleaner directly onto the keyboard. To remove any crumbs or dust from beneath the keys, you can use a camera blower with a brush or use cool air from a hair dryer.

Cleaning the computer screen: Scratches, oil, dust, chemicals, and ultraviolet light can affect the performance of your computer screen. Use a dry, soft lint-free cloth to wipe the screen gently. If you see a scratchlike mark on your screen, it might be a stain. Wipe or dust the stain gently with a soft, dry cloth. If the stain remains, moisten a soft, lint-free cloth with water or eyeglass cleaner, but do not apply liquids directly to your computer screen. Ensure that the computer screen is dry before closing it.
