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
