Heat And Product Ventilation; Computer Placement Notices - Lenovo ThinkCentre M710q User Manual

Heat and product ventilation

Computers, power adapters, and many accessories can generate heat when turned on and when batteries
are charging. Always follow these basic precautions:
• Do not leave the computer, power adapter, or accessories in contact with your lap or any part of your
body for an extended period when the products are functioning or when the battery is charging. The
computer, power adapter, and many accessories produce some heat during normal operation. Extended
contact with the body could cause discomfort or, potentially, a skin burn.
• Do not charge the battery or operate the computer, power adapter, or accessories near flammable
materials or in explosive environments.
• Ventilation slots, fans, and heat sinks are provided with the product for safety, comfort, and reliable
operation. These features might inadvertently become blocked by placing the product on a bed, sofa,
carpet, or other flexible surface. Never block, cover, or disable these features.
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.
