examine and remove dust from the inside of the computer including heat sink
inlet fins, power supply vents, and fans. Always turn off and unplug the computer
before opening the cover. If possible, avoid operating your computer within 2 feet
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

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.
