ABSTRACT:
A method and system are provided for thermal management of a portable computing apparatus. Accelerometers are provided to detect changes in attitude, and temperature sensors are provided to detect changes in temperature. A fan is used to cool the internal temperature of the electronic components of the computer. In response to lift of the computer from a stationary surface, the computer may transition to an alternative state of operation. The transition may include the change of the speed of the fan and/or adjustment of the processor clock.
