Abstract
A method of operating a computing device to allow events to be conditionally executed based on a power state of the device at the time of execution of the events. Conditional execution may be implemented using multiple timers, each associated with a power state. A timer such as an 'AC timer' or a 'DC timer' associated with a respective power state may be used to wake up the device when, upon expiration, or time-out, of the timer, a current power state of the device and the power state associated with the timer match. An Advanced Configuration Power Interface (ACPI) may be employed to abstract implementation of the timers from underlying hardware of the device. The operating system and software applications may request establishing wake-up behavior of the device as commands to program conditional events, which may then be translated into commands to embedded controller to set the timers.
