Variable clock cycle for processor, bus and components for power management in an information handling system
TLDR
In this article, a computer system that is able to switch processor and bus frequencies, along with processor voltage, when the system is placed into AC from battery power mode, and when the systems are placed into battery from AC power mode.Abstract:
A computer system that is able to switch processor and bus frequencies, along with processor voltage, when the system is placed into AC from battery power mode, and when the system is placed into battery from AC power mode. The computer system includes transitioning a processor (CPU) into a low performance mode using a clock generator that provides different clock frequencies, a high performance clock frequency and a low performance clock frequency depending on whether battery or AC power is used. The processor and interconnecting busses use the lower clock frequency in order to save battery power.read more

System and method for managing a plurality of processor performance states
TL;DR: In this article, a system and method for switching between a plurality of performance states is described. But it is not discussed how to determine when a performance state change is needed, only that a determination is made when the processor is in a quiescent state.

Changing clock frequency
TL;DR: In this article, the clock generator is reset by the clock frequency change indication to change the clock's frequency while the component is in a low activity state (e.g., deep sleep, stop grant, or other state).
Patent
Electronic circuit with power drain control
TL;DR: In this article, a power switching circuit is described for supplying power to a radio pager which must be continuously powered from either a main or backup battery, and the main battery voltage is monitored and at appropriate levels as its value falls, selected functions of the pager are eliminated and switch over to the backup battery is made to keep alive essential functions.
