Lenovo U330 manual Safety, Use, and Care Information

Chapter 6. Safety, Use, and Care Information

ƒPlace liquids away from your computer to avoid spills, and keep your computer away from water (to avoid the danger of electrical shock).

ƒDo not eat or smoke over your keyboard. Particles that fall into your keyboard can cause damage.

ƒStore packing materials safely out of the reach of children to prevent the risk of suffocation from plastic bags.

ƒKeep your computer away from magnets, activated cellular phones, electrical appliances, or speakers (within 13 cm or 5 in).

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

ƒSome appliances, such as certain portable desktop fans or air purifiers, can produce negative ions. If a computer is close to such an appliance, and is exposed for an extended time to air containing negative ions, it may become electrostatically charged. Such a charge may be discharged through your hands when you touch the keyboard or other parts of the computer, or through connectors on I/O devices connected to it. Even though this kind of electrostatic discharge (ESD) is the opposite of a discharge from your body or clothing to the computer, it poses the same risk of a computer malfunction.

Your computer is designed and manufactured to minimize any effects of electrostatic charge. An electrostatic charge above a certain limit, however, can increase the risk of ESD. Therefore, when using the computer close to an appliance that can produce negative ions, give special attention to the following:

-Avoid directly exposing your computer to the air from an appliance that can produce negative ions.

-Keep your computer and peripherals as far as possible from such an appliance.
