ABSTRACT:
Sharing a plurality of power resources among a plurality of devices using a set of data structures. Power dependencies are identified using a power management data structure defining which power resources must be on to support the device in a device state and a system state data structure defining which power resources must be off in a corresponding system state. These data structures are used by the operating system where a desired device state for a device is selected. The power management data structure corresponding to the device power state is read to determine which power resources must be on. Only the power resources that must be on are turned on and the power resources that are no longer being used are turned off before placing the device in the desired device power state.
