1. An electronic device comprising:
a memory;
a touch sensor overlaying a display; and
a lower power processor configured to:
receive a signature input using the touch sensor while the display operatively coupled with the lower power processor is in a continuous inactive state, wherein the signature input comprises a continuous input through a plurality of points on the touch sensor overlaying the display;
determine whether the signature input corresponds to a predetermined signature pattern while at least one other higher power processor is in the continuous inactive state; and
control the at least one other higher power processor to transition from the continuous inactive state to an active state and control the display to transition from the continuous inactive state to an active state, based at least in part on a determination that the signature input corresponds to the predetermined signature pattern;
wherein the lower power processor is configured to determine that the signature input corresponds to the predetermined signature pattern causes the display to transition from the continuous inactive state to the active state, the transitioning including turning on the display,
wherein the lower power processor is configured to refrain from activating the display based at least in part on a determination that the signature input does not match data, and
wherein the lower power processor is transitioned from the continuous inactive state to the active state in response to detection of removal of a stylus from a holster.
