Abstract: Examples of the disclosure are directed to a method of, after hitting a UVLO threshold, rebooting an electronic device in a low power mode having a lower UVLO threshold, such that the device can continue to be used past the first UVLO threshold. For example, in a high power mode, the device may be capable of a number of functionalities of a modern portable electronic device, such as network access, the ability to run applications, Bluetooth connections, etc. In a low power mode, the device may only be able to check and display a current time, play an alarm sound at a predefined time, perform near field communication (NFC) transactions/payments, among other possibilities described herein. The limited functionality and reduced usage of peripherals in the low power mode may prevent the battery from experiencing peaks in current level that may be problematic at relatively low levels of voltage.

Abstract: A portable computing device includes at least a base portion of a lightweight material that includes at least a wedge shaped top case having a trough formed at an interfacing edge thereof. The trough includes a raised portion having a first contact surface and a receiving area, and a bottom case coupled to the top case to form a complete housing for at least a portion of the portable computing device for enclosing at least a plurality of operational components and a plurality of structural components. The portable computing device also includes at least a lid portion pivotally connected to the base portion by a hinge assembly. In the described embodiments, the lid portion has a display in communication with one or more of the plurality of components in the base portion by way of or more electrical conductors that electrically connect the base portion to the lid portion.

Abstract: An interposer for electrically coupling a battery-management circuit board in a power supply and a motherboard is described. The interposer includes: a substrate having a top surface and a bottom surface; first spring connectors, disposed on the top surface, which electrically couple to the battery-management circuit board; and second spring connectors, disposed on the bottom surface and electrically coupled to the first spring connectors, which electrically couple to the motherboard. Spring connectors in a first subset of the first and second spring connectors that convey power signals have a first vertical height, and spring connectors in a second subset of the first and second spring connectors that convey monitoring signals for the power supply have a second, smaller vertical height. In this way, the first subset is activated before the second subset is activated, thereby ensuring that an electrical path for the power signals is established first.
