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:











v
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.












v
Do not charge the battery or operate your computer, AC adapter, or













accessories 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 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
