ABSTRACT:
A system for managing power consumption in a personal computer, specifically peripheral devices including the display and other external devices such as disk drives, CD-ROM drives, modems and the like. A software and hardware architecture is provided for managing the power consumption of peripheral devices through their device drivers and a global event messaging scheme. A set of power events is defined which are delivered to device drivers, through an associated power management handler. Each driver can make the decision as to whether that power event should affect its coupled device's power state.
