Facilité d'utilisation
damaged, or if you notice any discharge from your battery or the buildup of foreign
materials on the battery leads, stop using the battery and obtain a replacement
from the battery manufacturer.
Batteries can degrade when they are left unused for long periods of time. For
some rechargeable batteries (particularly Lithium Ion batteries), leaving a battery
unused in a discharged state could increase the risk of a battery short circuit,
which could shorten the life of the battery and can also pose a safety hazard. Do
not let rechargeable Lithium-Ion batteries completely discharge or store these
batteries in a discharged state.
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 your 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. Your 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 your 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 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.
