SLEEP WAKE EVENT LOGGING

摘要

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.

1. A computer-implemented method executed in a data processing apparatus comprising:
detecting a trigger of a low power event on the data processing apparatus, wherein the data processing apparatus, responsive to the trigger of the low power event, will begin to enter a low power mode of operation; creating an identifier specific to the occurrence of the low power event, and associating the identifier with the low power event, the identifier distinguishing the low power event from other low power events; monitoring a plurality of system events occurring after detection of the trigger; determining whether an exit event completed, the exit event indicating an exit from the low power mode of operation; and logging each of the plurality of system events until a completion of the exit event is detected, wherein each system event is logged using the identifier.
