Batteries

All personal computers manufactured by Lenovo contain a non-rechargeable coin cell battery to provide power to the

system clock. In addition many mobile products such as ThinkPad notebook PCs 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 Lenovo 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 generate heat when turned on and when batteries are charging. Notebook PCs can generate a significant

amount of heat due to their compact size. Always follow these basic precautions:

v Do not leave the base of your computer in contact with your lap or any part of your body for an extended period

when the computer is functioning or when the battery is charging. Your computer produces some heat during normal

operation. Extended contact with the body could cause discomfort or, potentially, a skin burn.

v Do not operate your computer or charge the battery near flammable materials or in explosive environments.

v Ventilation slots, fans and/or 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.
