Abstract
An asynchronous state machine (ASM) for managing deep sleep state of a device and related methods are described. One method includes the ASM automatically detecting a request to wake up the device based on either a change in a status of a power user-interface element associated with the device or upon a detection of an attachment of an external power source to the device. The method further includes the ASM automatically initiating a wake-up sequence including turning on a battery pack associated with the device. The method further includes the ASM automatically detecting whether a power management function associated with the device is enabled and automatically transferring control of a remaining portion of the wake-up sequence to the power management function and the ASM passing the status of the power user-interface element to the power management function as needed.
