System and method for multi-user state change
A system for configuring an information handling system based on a multi-user state change. An intelligent sensor hub communicates with sensors to detect the number of persons in a field of view of the information handling system. When the intelligent sensor hub determines there is a change in the number of persons, the information is sent out-of-band to an embedded controller (EC) independent of a host operating system. The EC makes a change to the configuration of the information handling system if needed.
