Abstract: A method and an apparatus for a power assertion management are described. A power assertion indicator may be maintained for a device component having a power level. The power assertion indicator can indicate whether the power level of the device component is allowed to be lowered. A power assertion request may be sent from a first process to prevent lowering the power level of the device component before a data processing task is completed. A second process can receive a request from the first process to perform operations for the data processing task. The power level of the device component may not be allowed to be lowered before the second process completes the operations for the data processing task. The power level of the device component may be lowered after the data processing task is completed.

Abstract: A machine implemented method includes creating a universally unique identifier, detecting a trigger of a sleep event, and associating the universally unique identifier with the sleep event. The method monitors sub-system events that occur after a sleep event has been triggered and stores data in non-volatile non-disk storage (e.g., non-boot storage) identifying an event stage corresponding to the sub-system event that is occurring. The method determines whether a wake event has completed and logs each of the sub-system events using the universally unique identifier until a wake event has completed.
