Abstract

A power manager within a portable laptop computer provides power and clocking control to various units within the computer in order to conserve battery power. Transistor switches controlled by the power manager control the distribution of power and/or clock signals to the various units within the computer. The power manager includes a software routine for continually monitoring the various units and when these units are either not needed and/or not currently in use, power and/or clock signals are removed from a given unit.
