System and method for heuristics based user presence detection for power management

An method for managing power of an information handling system based on heuristically detected user presence comprising:

• operating an information handling system according to a full power protocol;
• receiving one or more inputs indicating user absence determined based on information gathered by one or more of a plurality of sensor devices;
• identifying a user absence confidence level associated with the one or more inputs indicating user absence in a human absence confidence table stored in a memory;
• and
• initiating a low power protocol after a first preset time period if the identified user absence confidence level meets a preset low power threshold value.

An information handling system operating a heuristic user presence based power management system comprising:

• a video display;
• a plurality of user presence sensors;
• a processor operatively connected to a memory and operating the information handling system according to a low power protocol;
• and
• the processor executing machine readable executable code instructions of the heuristic user presence based power management system to receive one or more inputs indicating user presence determined based on information gathered by one or more of a plurality of sensor devices, identify a user presence confidence level associated with the one or more inputs indicating user presence in a human presence confidence table stored in the memory, and initiate a full power protocol, if the identified user presence confidence level meets a preset full power threshold value.
