Abstract
A computing device can include 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 battery, the power interface and the magnet control circuitry, where the housing includes 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, where 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.
