Abstract
Electronic circuits and methods are provided for conserving power within computers and other apparatus. A logic circuit performs a logical operation on a plurality of variables thus deriving a corresponding output. The output is used to drive and maintain an open or closed state of an electronic switch, accordingly. The electronic switch is disposed between a source of electrical energy and a system power buss of a computer. The computer can assume very low power, full power and other respective operating modes in accordance with the present state of the electronic switch.
