Claim 8:
9. A method of an electronic device, the method comprising:
detecting whether an electronic pen is detached from the electronic device via a sensor circuit;
activating, by at least one processor, a digitizer panel based on detecting detachment of the electronic pen from the electronic device;
identifying a state of the electronic pen while maintaining a communication linkage with the electronic pen via a communication circuit; and
while the electronic pen remains detached from the electronic device, deactivating the activated digitizer panel based on the identified state of the electronic pen,
wherein deactivating the activated digitizer panel comprises:
identifying a distance to the electronic pen based on a strength of a communication signal with the electronic pen,
identifying whether a movement of the electronic pen is detected for a designated time based on sensor information received from the electronic pen; and
deactivating the activated digitizer panel in case that the identified distance is greater than a predefined threshold distance and the movement of the electronic pen is not detected for the designated time.
