Intelligent control of a power supply system of an information handling system

A method comprising:

• receiving power from an adapter;
• providing the power from the adapter to a switching power supply having a switching network including a plurality of power switching elements;
• controlling the plurality of power switching elements to provide system power to an information handling system through the switching power supply;
• detecting a light loading power condition of the information handling system;
• in response to detecting the light loading power condition of the information handling system,
• deactivating the switching power supply, and
• activating a bypass control module wherein
• activation of the bypass control module directs power from the adapter through the bypass control module to the information handling system as the system power;
• controlling the plurality of power switching elements to provide system power to the information handling system using a charger controller when system power is provided by the switching power supply;
• detecting the light loading power condition at an embedded controller of the information handling system;
• using the embedded controller to communicate with the charger controller to instruct the charger controller to deactivate the switching power supply;
• using the embedded controller to communicate with a power delivery device, wherein the power delivery device directs the adapter to adjust a voltage output of the adapter to a predetermined voltage level;
• activating a bypass control signal at an output of the embedded controller in response to the detection of the light loading power condition;
• and
• receiving the bypass control signal at an input of the bypass control module to activate the bypass control module, wherein
• activation of the bypass control module directs power from the adapter to the information handling system as the system power.

An information handling system comprising:

• a power port configured for connection to an adapter;
• a power supply system configured to receive power from the adapter through the power port, wherein
• the power supply system is operable in a first mode of operation in which system power is provided to the information handling system by a switching power supply having a plurality of switching elements, and
• the power supply system is operable in a second mode of operation in which the system power is provided to the information handling system by the adapter, wherein the switching power supply is deactivated in the second mode of operation;
• and
• a power control system configured to operate the power supply system in the first mode of operation and the second mode of operation, wherein
• the power control system operates the power supply system in the second mode of operation when the information handling system is in a light loading power condition, and
• the power control system operates the power supply system in the first mode of operation when the information handling system exits the light loading power condition;
• a charger controller configured to control the switching elements of the switching power supply to control power provided by the switching power supply when the power supply is operating in the first mode of operation;
• a power delivery device configured for communication with the adapter;
• and
• an embedded controller configured for communication with the charger controller, the bypass control module, and the power delivery device.

A non-transitory, computer-readable storage medium embodying computer program code, the computer program code comprising instructions executable by an embedded controller, the instructions being configured for:

• directing a power supply system to operate in a first mode of operation in which system power is provided to an information handling system by a switching power supply having a plurality of switching elements, wherein power is provided to the plurality of switching elements from an adapter;
• and
• detecting a light loading power condition of an information handling system;
• in response to detecting the light loading power condition of the information handling system,
• directing the power supply system to operate in a second mode of operation, wherein
• the system power is provided to the information handling system by the adapter, and
• the switching power supply is deactivated;
• communicating with a charger controller of the switching power supply to direct operation of the charger controller in the first mode of operation and the second mode of operation, wherein
• the charger controller is directed to provide power through the switching elements of the switching power supply in the first mode of operation of the power supply system, and
• the charger controller is directed to deactivate the switching power supply in the second mode of operation.
