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:
vDo 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.
vDo not operate your computer or charge the battery near flammable materials or in explosive environments.
vVentilation 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.

To protect against possible injury due to this situation, and to reduce the risk of damage to your machine, do the following:
vAlways store CD/DVD discs in their original packaging
vAlways store CD/DVD discs out of direct sunlight and away from direct heat sources
vRemove CD/DVD discs from the computer when not in use
vDo not bend or flex CD/DVD discs, or force them into the computer or their packaging
vCheck CD/DVD discs for cracks before each use. Do not use cracked or damaged discs
