1. A computing system comprising:
an enclosure including a housing coupled to a display window;
a battery within the enclosure;
a plurality of inductive charging transmit coils coupled to the battery and positioned within the enclosure adjacent the display window to generate an inductive charging region that extends through the display window and across at least a portion of an exterior of the display window;
sensing circuitry positioned at the display window and configured to sense a position of a stylus at the display window, wherein the sensing circuitry is separate from the inductive charging transmit coils; and
a processor configured to selectively engage one or more of the plurality of inductive charging transmit coils based on the sensed position of the stylus.
