Chapter 6. Safety, Use, and Care Information
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.
- Wherever possible, ground your computer to facilitate safe electrostatic
discharge.
Note:
Not all such appliances cause a significant electrostatic charge.
