Provide adequate ventilation
Always make sure that your computer and AC adaptor have adequate
ventilation and are protected from overheating when the power is turned on
or when an AC adaptor is connected to a power outlet (even if your
computer is in Sleep Mode). In this condition, observe the following:
Overheating your computer or AC adaptor could cause system failure,
computer or AC adaptor damage or a fire, possibly resulting in serious
injury.
Creating a computer-friendly environment
Place the computer on a flat surface that is large enough for the computer
and any other items you are using, such as a printer.
Leave enough space around the computer and other equipment to provide
adequate ventilation. Otherwise, they might overheat.
To keep your computer in prime operating condition, protect your work area
from:
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. It also includes information
on work space design, posture, and lighting that can help reduce physical
stress.
