  • Patent number: 9760150
    Abstract: 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.

  • Patent number: 9479001
    Abstract: A regulator draws power from a battery or power delivery system and supplies regulated power to a load according to alternating modes of operation. In a voltage control mode, the regulator supplies power with a nominal voltage level and a fluctuating current level that is allowed to float according to the current demands of the load. When the load demands an amount of current that could potentially cause damage, the regulator transitions to a current control mode. In the current control mode, the regulator supplies power with a fluctuating voltage level and a maximum current level. The regulator transitions between voltage control mode and current control mode in order to supply a maximum power level to the load without exceeding the maximum current level. The regulator is also configured to limit the power drawn from the battery by decreasing the maximum output current, potentially avoiding voltage droop.
