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:

or, potentially, a skin burn.
v Do not operate your computer or charge the battery near flammable materials or in explosive
