Abstract
Methods of waking a portable electronic device are disclosed. In one embodiment, the method comprises: causing the portable electronic device to enter a sleep mode in which a touch-sensitive display is deactivated a force sensing transducer measures forces applied to the touch-sensitive display at a reduced rate relative to a rate of a full power mode when in the sleep mode; causing a force sensing transducer to measure forces applied to the touch-sensitive display at the rate of the full power mode in response to detection of an inertial event; causing the touch-sensitive display to be reactivated in response to detection of a force which is greater than a predetermined wake force threshold; and causing the portable electronic device to wake in response to detection of a touch event within a first predetermined duration of the detection of the force which is greater than a predetermined wake force threshold.
