1. A computing device comprising:
a processor;
memory accessible to the processor;
a lithium-ion battery;
a power interface;
magnet control circuitry operatively coupled to at least the power interface for receipt of electrical power; and
a housing for the processor, the memory, the lithium-ion battery, the power interface and the magnet control circuitry, wherein the housing comprises a first shell, a second shell, and an electropermanent magnet assembly that generates a magnetic force that couples the first shell to the second shell, wherein the electropermanent magnetic assembly is controllable via the magnet control circuitry to decrease the magnetic force to decouple the first shell from the second shell.
