Batteries
DANGER
Personal computers manufactured by Lenovo contain a 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.
This system does not support batteries that are not genuine Lenovo-made or authorized. The
system will continue to boot, but may not charge unauthorized batteries. Attention: Lenovo has no
responsibility for the performance or safety of unauthorized batteries, and provides no warranties
for failures or damage arising out of their use.
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 ame
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.
