Inspect your desktop computer for dust accumulation at least once every three months. Before inspecting
the computer, turn off the power and unplug the computer's power cord from the electrical outlet; then
remove any dust from vents and perforations in the bezel. If you notice external dust accumulation, then
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 the
computer within two feet of high-traffic areas. If you must operate the computer in or near a high-traffic
area, inspect and, if necessary, clean the 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 the 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 install air filtration devices. They may interfere with proper cooling.
Operating environment
The optimal environment in which to use the computer is 10°C–35°C (50°F–95°F) with humidity ranging
between 35% and 80%. If the 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 the computer to rise to an optimal
operating temperature before use could result in irreparable damage to the computer.
If possible, place the 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 the computer because the strong magnetic fields generated by these appliances
can damage the monitor and data on the storage drive.
Do not place any beverages on top of or beside the computer or other connected devices. If liquid is spilled
on or in the computer or a connected 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.
