US Patent 9239605 Computing device power state transitions

Methods and apparatus for scheduling and controlling power management activities are disclosed. An example method includes automatically scheduling a wake-up alarm for a computing device and transitioning the computing device from an active power state to a first low power state. The example method also includes, in response to occurrence of the automatically scheduled wake-up alarm, transitioning the computing device from the first low power state to the active power state and transitioning the computing device from the active power state to a second low power state, where the second low power state is a lower power state than the first low power state.
