Chapter 6. Safety, use, and care information
ƒ Place liquids away from your computer to avoid spills, and keep your
computer away from water (to avoid the danger of electrical shock).
ƒ Do not eat or smoke over your keyboard. Particles that fall into your
keyboard can cause damage.
ƒ Store packing materials safely out of the reach of children to prevent the
risk of suffocation from plastic bags.
ƒ Keep your computer away from magnets, activated cellular phones,
electrical appliances, or speakers (within 13 cm or 5 in).
ƒ Avoid subjecting your computer to extreme temperatures (below 5°C/
41°F or above 35°C/95°F).
ƒ Some 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.
