1. A method of entering a power conservation state, the method comprising: detecting a system idle event of a computer system; selecting and entering one of a plurality of low power states for the computer system in response to the detected system idle event, wherein the plurality of low power states comprise: a first low power state for the computer system, wherein: a memory of the computer system is self refreshed and an application processor module of the computer system is unpowered during the first low power state; a second low power state for the computer system, wherein: during the second low power state, the application processor module is unpowered; a baseband module is active for performing a network paging activity; the memory of the computer system is accessible to the baseband module; and the baseband module accesses the memory through a direct path into a memory sequencer of a memory controller associated with the application processor; a third low power state for the computer system, wherein, during the third low power state: the baseband module is active for performing a voice call activity during which the application processor is unpowered; an audio module of the computer system is active; and the memory of the computer system is accessible to the baseband module, and wherein the one of the plurality of low power states is selected depending upon baseband module activity; and exiting from the one of the plurality of low power states when a wake event is detected.
