General Precautions
To keep your computer in prime operating condition, protect your work area
from:
■ Dust, moisture, and direct sunlight.
■ Equipment that generates a strong electromagnetic field, such as
stereo speakers (other than speakers that are connected to the
computer) or speakerphones.
■ Rapid changes in temperature or humidity and sources of temperature
change such as air conditioner vents or heaters.
■ Extreme heat, cold, or humidity.
■ Liquids and corrosive chemicals.
Stress injury
Carefully read the Instruction Manual for Safety and Comfort. It contains
information on the prevention of stress injuries to your hands and wrists
that can be caused by extensive keyboard use.
Heat injury
■ Avoid prolonged physical contact with the computer. If the computer is
used for long periods, its surface can become very warm. While the
temperature will not feel hot to the touch, if you maintain physical
contact with the computer for a long time, for example if you rest the
computer on your lap or if you keep your hands on the palm rest, your
skin might suffer a low-heat injury.
■ If the computer has been used for a long time, avoid direct contact with
the metal plate supporting the various interface ports as this can
become hot.
■ The surface of the AC adaptor can become hot when in use but this
condition does not indicate a malfunction. If you need to transport the
AC adaptor, you should disconnect it and let it cool before moving it.
■ Do not lay the AC adaptor on a material that is sensitive to heat as the
material could become damaged.
Pressure or impact damage
Do not apply heavy pressure to the computer or subject it to any form of
strong impact as this can damage the computer's components or otherwise
cause it to malfunction.
ExpressCard overheating
Some ExpressCards can become hot during prolonged use which may
result in errors or instability in the operation of the device in question. In
addition, you should also be careful when you remove an ExpressCard that
has been used for a long time.
