Safety and warranty guide
of high-traffic areas. If you must operate your computer in or near a high-traffic
area, inspect and, if necessary, clean your computer more frequently.
For your safety and to maintain optimum computer performance, always follow
these basic precautions with your desktop computer:
• Keep the cover closed whenever the computer is plugged in.
• Regularly inspect the outside of the computer for dust accumulation.
• Remove dust from vents and any perforations in the bezel. More frequent
cleanings might be required for computers in dusty or high-traffic areas.
• Do not restrict or block any ventilation openings.
• Do not store or operate your computer inside furniture, as this might increase
the risk of overheating.
• Airflow temperatures into the computer should not exceed 35° C (95° F).
• Do not use non-desktop air filtration devices.
Operating environment
The optimal environment in which to use your computer is 10°C-35°C (50°F-95
°F) with humidity ranging between 35% and 80%. If your computer is stored or
transported in temperatures less than 10°C (50°F), allow the cold computer to rise
slowly to an optimal operating temperature of 10°C-35°C (50°F-95°F) before use.
This process could take two hours in extreme conditions. Failure to allow your
computer to rise to an optimal operating temperature before use could result in
irreparable damage to your computer.
If possible, place your computer in a well-ventilated and dry area without direct
exposure to sunshine.
Keep electrical appliances such as an electric fan, radio, high-powered speakers,
air conditioner, and microwave oven away from your computer because the strong
magnetic fields generated by these appliances can damage the monitor and data
on the hard disk drive.
Do not place any beverages on top of or beside the computer or other attached
devices. If liquid is spilled on or in the computer or an attached device, a short
circuit or other damage might occur.
Do not eat or smoke over your keyboard. Particles that fall into your keyboard can
cause damage.
