1. A method of coordinating events in a microprocessor-based electronic device having a sleep mode, the method comprising the steps of:

  • determining a list of event times to perform associated operating system events that require exiting sleep mode and entering a wake-up period to perform the event tasks;

    establishing a timing of fixed events wherein the electronic device exits the sleep mode and enters a wake-up period to perform the fixed events; and

    delaying the event time for at least one of the operating system events to align with a fixed event such that the electronic device utilizes one wake-up period to perform both of the at least one of the operating system event and the fixed event.
