Lenovo Secure Managed Client - Manual (Page 12)

Never attempt to open or service any battery. Do not crush, puncture, or
incinerate batteries or short circuit the metal contacts. Do not expose the
battery to water or other liquids. Only recharge the battery pack strictly
according to instructions included in the product documentation.
Battery abuse or mishandling can cause the battery to overheat, which can
cause gasses or flame to “vent” from the battery pack or coin cell. If your
battery is 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
Some products can generate heat when turned on and when batteries are
charging. Always follow these basic precautions:
v Do not leave your product 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 product may produce some heat during normal
operation. Extended contact with the body could cause discomfort or,
potentially, a skin burn.
v Do not charge the battery or operate your product near flammable materials
or in explosive environments.
v 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 product for dust accumulation at least once every three months.
Before inspecting your product, turn off the power and unplug the 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 product including heat sink inlet fins, power
supply vents, and fans. Always turn off and unplug the product before
opening the cover. If possible, avoid operating your product within 2 feet of
high-traffic areas. If you must operate your product in or near a high-traffic
area, inspect and, if necessary, clean your product more frequently.
For your safety and to maintain optimum product performance, always follow
these basic precautions:
