Abstract
One embodiment provides a method of managing power in a computer system. A device of the computer system is operated at a selected power-state. The power consumption of the computer system is monitored. If the power consumption of the computer system is approaching or has exceeded a power cap selected for the computer system, then a request to reduce the power-state for the device is generated in response. The operating system is used to service the request to reduce the power-state according to the priority of the request. The reduced power state is forced out-of-band following the request to reduce the power-state if the request is not immediately serviceable by the operating system. Different approaches can be taken to force the reduced power state, using, for example, system management mode or a platform environment control interface.
