ABSTRACT:
A portable computing device includes at least three buttons and circuitry for sensing the pressing of at least three buttons, one being recessed, and in response to such sensing provides a battery disable signal to a non-removable battery. The portable computing device further includes circuitry for sensing the coupling of the device to a device cradle, and in response to such coupling, or in response to the press of the recess button, provides a battery enable signal to the non-removable battery.
