Abstract

A laptop computer protective bag, including a supportive front wall, a back wall, and a substantially rigid bridge wall that holds the front wall inclined relative to the back wall when the computer is in use resting on the front wall. Flexible side walls form a closed chamber with extremities of the front and rear walls being in close proximity when toe computer is in use, a pair of fans blowing air through the front wall for cooling a bottom surface of the computer, a vent structure permitting the air to flow through the chamber. Also disclosed is a backpack assembly that incorporated the protective bag.
