General safety guidelines xiii
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 power 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 power 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 power 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 power
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.
