Though your computer is designed to function reliably in normal work
environments, you need to use common sense in handling it. By following
these important tips, you will get the most use and enjoyment out of your
computer.
Be careful about where and how you work.
• Do not eat or smoke over your keyboard. Particles that fall into your
keyboard can cause damage.
• Store packing materials safely out of the reach of children to prevent the
risk of suffocation from plastic bags.
• Keep your computer away from magnets, activated cellular phones,
electrical appliances, or speakers (within 13 cm or 5 in).
• Avoid subjecting your computer to extreme temperatures (below 5°C/41°F
or above 35°C/95°F).
• 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.
