coin cell battery to provide power to the system clock. In addition, many mobile
products, such as notebook computers, utilize a rechargeable battery pack to
provide system power when in portable mode. Batteries supplied by Lenovo
for use with your product have been tested for compatibility and should only be
replaced with approved parts.
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
Computers, AC 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, AC 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, AC 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, AC 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
