  • during the execution of a sleep sequence by an operating system on the computer system, latching events associated with use of the computer system;

    after the sleep sequence has completed, comparing the latched events with a set of enabled wake events for the computer system and a state variable, wherein the state variable comprises a set of bits, wherein each bit tracks occurrences of an associated event, and can be set or cleared based on occurrences of the associated event; and

    if the latched events and the state variable are consistent with one of the enabled wake events, triggering a wake sequence on the computer system.
