Abstract: Methods of assembly are provided for an AC plug supporting foldable prongs. The AC plug includes: a cover including slots and prongs. In an extended position, the prongs are insertable in AC outlet receptacles and each prong contacts a spring mounted terminal that is coupled to a power circuit. In a retracted position, each prong is recessed in a slot of the cover and does not contact a spring mounted terminal. In the extended position, the coupling between each prong and the power circuit does not utilize wires. A first end of each spring mounted terminal is positioned on a contact pad of a printed circuit board (PCB) that connects the AC plug to the power circuit. A cap is fastened to the cover and secures the spring mounted terminals to the respective contact pads and secures the PCB and spring mounted terminal to the cover.

Abstract: An AC adapter charges an Information Handling System (IHS) and includes a first DC plug including a DC connector that is compatible with an IHS power port. The first DC plug includes a first light guide for receiving light transmitted from the IHS and for illuminating an indicator of the first DC plug. The first DC plug comprises a fiber optic wire that receives the light received by the first light guide and illuminates the indicator. The fiber optic wire may extend within the DC cord and may illuminates an indicator of a second DC plug on the opposite end of the DC cord. The DC cord may include one or more indicators illuminated by the fiber optic wire extending within the DC cord. The fiber optic wire terminates at a light guide of the second DC plug and exits the light guide of the second DC plug when the second DC plug is uncoupled.

Abstract: Techniques for adaptive power management for non-chiral auxiliary wireless power modules include receiving, by a wireless charging mat, DC input power, determining, dependent on the DC input power, a budget for inductive power available for charging portable devices placed on the wireless charging mat, detecting, at a first port, a connection by a first auxiliary wireless charging mat, determining an amount of power to be provided to the first auxiliary wireless charging mat, determining, dependent on the amount of power to be provided to the first auxiliary wireless charging mat, a reduced budget for the inductive power available for charging portable devices, and providing the determined amount of power to the first auxiliary wireless charging mat. In response to detecting a connection by a second auxiliary charging mat or a portable device at a second port located opposite the first port, the inductive power budget may be further modified.

Abstract: An information handling system (IHS) includes a battery management unit (BMU) and an embedded controller (EC). The EC is operable for detecting a trigger for monitoring power consumption in light of a first condition, capturing a state of the IHS, writing data representing the state to a power profile log, annotating the log with an identifier of a point at which logging associated with the first condition begins, obtaining, from the BMU, power data representing an amount of current flowing from or charge delivered by a battery, writing at least some power data to the log, detecting a trigger for ending monitoring associated with the first condition, annotating the log with an identifier of a point at which logging associated with the first condition ends, and generating, dependent on the annotations of the identifiers in the log, a power profile report indicating power consumption associated with the first condition.

Abstract: A power storage adapter (PSA) may be connected to multiple battery-powered devices. A PSA controller may be configured to receive respective requests to supply electrical power to a first device and a second device, to determine that the power storage adapter does not have sufficient power supply capacity to satisfy both requests, to determine that a respective state of charge (SOC) of at least one device battery is below a first battery SOC threshold, and to prioritize supplying electrical power to a selected one of the devices at the expense of the other device based on a battery charging prioritization policy. The selected device may be prioritized until the battery SOC exceeds a battery SOC threshold or for a predetermined time period. The battery charging prioritization policy may specify relative charging priorities for the device batteries and a PSA battery dependent on whether AC line power is available.
