Abstract:
The disclosed embodiments provide a system that performs power management on a computer system. The system includes an embedded controller and an operating system. During the execution of a sleep sequence by the operating system, the embedded controller latches events associated with use of the computer system. After the sleep sequence has completed, the embedded controller compares the latched events with a set of enabled wake events for the computer system and a current state of the computer system. If the latched events indicate that the current state corresponds to one of the enabled wake events, the embedded controller triggers a wake sequence on the computer system.
