Techniques of charging electronic devices involve directing electrical power from a first device to the battery of a second device in response to the first device being in a first state, and directing electrical power from the second device to the battery of the first device in response to the first device being in a second state. For example, in response to a connection being established between a first device (e.g., a tablet computer) and a second device (e.g., a monitor), a charger of the first device detects a state of charge of the battery of the first device and a state of charge of the second device.

Hot-pluggable dual battery with pass through charging

A computing system is configured to securely boot different operating systems. The computing system includes one or more processors, a first memory device storing a first firmware element for booting a first operating system, a second memory device storing a second firmware element for booting a second operating system, a first security module configured to provide authentication for booting the first operating system, and a second security module configured to provide authentication for booting the second operating system. The computing system is configured such that, when the first security module is connected to the one or more processors, either the first operating system or the second operating system is selected for booting based on a selection signal, and when the first security module is not connected to the one or more processors, the second operating system is selected for booting.

Enabling multiple secure boot paths on a hardware platform

The embodiments provide a device including an enclosure having circuitry associated with the device and a battery configured to power the circuitry, and a power plug receiving unit configured to receive a power plug of a power charger to charge the battery. The power plug receiving unit includes a ground contact that is exposed through the enclosure for contact with a secondary ground contact of the power plug, and an active electrode configured to receive alternating current (AC) energy from the power charger for charging the battery or powering the circuitry via non-contact coupling.

Charging mechanism with ground contact and non-contact coupling

Aspects of the subject technology relate to a compliance station including a test breakout board coupled to a computing device and a trusted platform module, wherein the test breakout board is configured to allow signaling to pass between the computing device and the trusted platform module and a test controller interface coupled to the test breakout board. In certain aspects, the test controller interface is configured to provide signaling to the trusted platform module and to receive signaling from the trusted platform module. A method and computer-readable medium are also provided.
