Supervisory control of power management

A supervisory power management control system for an electronic device, the supervisory power management control system configured to:

• monitor activity information regarding a hardware component of the electronic device;
• set a timeout period associated with the hardware component, the timeout period defining a minimum amount of time before a power state of the hardware component may be transitioned from a higher-power state to a lower-power state;
• transition at least a portion of the hardware component to a lower-power state if the hardware component satisfies a transition condition, the transition condition being dependent at least in part on the activity information and the timeout period;
• and
• maintain the hardware component in the higher-power state after expiration of the timeout period if the hardware component does not satisfy the transition condition during the timeout period.

One or more tangible processor-readable storage media embodied with instructions for executing on one or more processors and circuits of a device a process for supervisory power management of an electronic device, the process comprising:

• monitoring activity information of a hardware component of the electronic device;
• setting a timeout period for the hardware component of the electronic device, the timeout period having an initial value based on the activity information;
• and
• transitioning at least a portion of the hardware component from a higher-power state to a lower-power state after expiration of the timeout period if the hardware component satisfies a transition condition, the transition condition being dependent at least in part on the activity information and the timeout period.
