1. A tablet device capable of carrying a protective cover, the protective cover having a protective cover magnetic element and an inductive power transmitter, the tablet device comprising:
- a housing with a front opening; and
operational components carried by the housing that include;
a processor in communication with;
(i) a sensor capable of detecting a magnetic field, (ii) a display assembly having a display coupled to the processor and overlaid by a protective layer disposed within the front opening, (iii) an inductive power receiver, and (iv) a battery coupled to the inductive power receiver,wherein the tablet device is capable of sending a signal to the protective cover that enables the protective cover to use the inductive power transmitter to inductively pass power through the protective layer to the inductive power receiver in accordance with a current battery state of the battery.
