Power system components are mapped using a controller and a data collection system. The controller is operable to transmit a first power system component ID for the first power system component to a second power system component, wherein the second power system component receives power from the first power system component. The data collection system is operable to receive from the second power system component the first power system component ID and a second power system component ID for the second power system component. The data collection system is further operable to associate the first power system component with the second power system component based on the received IDs.

Mapping power system components

Short duration micro-sleep or nap periods reduce the power consumption of a computing device. In use, the computing device determines a first duration to a next expected event in the computing device, and compares the first duration to a minimum micro-sleep duration. If the first duration is greater than or equal to the minimum duration, then the processor enters a processor sleep state for a sleep duration. The processor then wakes up and returns to a running state at the end of the sleep duration and before the next expected event. This permits the use of a low-power sleep state while giving the appearance that the computing device is functional. As an additional requirement before entering micro-sleep, the current or recent processor load may be evaluated to determine whether a micro-sleep interval is appropriate.
