1. A method comprising:
monitoring an information handling system, by a processor, to detect a transition of a signal from a magnetic sensor, wherein the transition of the signal from the magnetic sensor indicates a change in a state of a lid of the information handling system from a first state to a second state;
in response to detecting the transition of the signal, determining, by an embedded controller, an angle of the lid based on information from an inertial sensor, wherein the angle of the lid is used to determine a lid state flag;
confirming, by the embedded controller, whether the lid is at the second state based on an output of a logic module, that takes the lid state flag from the inertial sensor and the signal from the magnetic sensor as inputs, wherein the output of the logic module is a logical high signal; and
in response to the logical high signal as the output of the logic module, performing a power sequence.
