							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 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: 
v   
 Do 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. 
v 
 
 Do not operate your computer or charge the battery near flammable materials or 
in explosive environments. 
v 
 
 Ventilation 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.
CD and DVD drive safety 
CD and DVD drives spin discs at a high speed. If a CD or DVD is cracked or 
otherwise physically damaged, it is possible for the disc to break apart or even 
shatter when the CD drive is in use. To protect against possible injury due to this 
situation, and to reduce the risk of damage to your machine, do the following: 
v 
 
 Always store CD/DVD discs in their original packaging 
v 
 
 Always store CD/DVD discs out of direct sunlight and away from direct heat 
sources 
v 
 
 Remove CD/DVD discs from the computer when not in use 
v 
 
 Do not bend or flex CD/DVD discs, or force them into the computer or their 
packaging 
v 
 
 Check CD/DVD discs for cracks before each use. Do not use cracked or 
damaged discs
