LOW-POWER STATES FOR A COMPUTER SYSTEM WITH INTEGRATED BASEBAND

摘要

A method of entering a power conservation state comprises selecting and entering one of a plurality of low power states for the computer system in response to a detected system idle event. The plurality of low power states comprise a first low power state and a second low power state for the computer system. A memory of the computer system is self refreshed during the first low power state. A baseband module of the computer system remains powered, and the memory is accessible to the baseband module during the second low power state. The one low power state is selected depending upon baseband module activity. The method also includes exiting from the one of a plurality of low power states when a wake event is detected.
