I heard somewhere that it is dangerous to place a laptop on a bed. The reason given was that placing the laptop on the bed blocks (assume that the laptop does not have sideway fans - it only has air holes or air intake fans at the bottom.) the air intake fans of the laptop. However, we often place our laptops on a table or desk. So, what makes the laptop to over-heat when placed on a bed?
Also, If one places a laptop on a pile of books, will the laptop over-heat?
