Safety and warranty guide

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 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.
