Inspect your desktop computer for dust accumulation at least once every three months. Before inspecting
your 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
your computer within two 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 install air filtration devices. They may interfere with proper cooling.
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 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.
Laser compliance statement

When laser products (such as CD-ROMs, DVD drives, fiber optic devices, or transmitters) are
installed, note the following:
• Do not remove the covers. Removing the covers of the laser product could result in exposure to
hazardous laser radiation. There are no serviceable parts inside the device.
• Use of controls or adjustments or performance of procedures other than those specified herein
