An information handling system includes a bottom case and a wireless charging puck. The bottom case includes a bay. The wireless charging puck fits into the bay, and is detachable from the bottom case. When the wireless charging puck is fitted into the bay, the wireless charging puck is configured as a power receiving unit to receive wireless power. When the wireless charging puck is detached from the bay, the wireless charging puck is configured as a power transmitting unit to provide wireless power to an external device.

An information handling system having a display magnetically couples a peripheral camera to the display with a magnet included in the camera housing. A colorimeter located proximate the magnet detects colors presented at the display at a position where the peripheral camera couples to the display. Iteratively comparing colors presented at the display with colors detected by the colorimeter determines a position of the peripheral camera. The algorithm has a more rapid response by predicting the camera position, such as near a videoconference window. Incremental changes to colors presented at the display so that the presented colors do not match colors of content of an end user yet are indistinguishable to the human eye aid in providing a definitive peripheral camera location.

Systems and methods for aligning an electronic device to a wireless charging pad disposed under a work surface are described. In some embodiments, a system may include a printed circuit board (PCB) and a light indicator coupled to the PCB, where the light indicator is configured to connect to a wireless charging pad disposed under a work surface, and where light emitted by the light indicator is visible to a user from above the work surface.

A camera integrates a magnet at one end of a housing to magnetically attract and attach the camera to a front side of a peripheral display, such as to support a video conference through an information handling system interfaced with the display. Camera position movement at a display panel front face is detected, such as with a touchscreen of the display panel, and accelerometer or an infrared curtain presented from the camera dock along the display panel front face. Audio and visual information communicated from the camera is altered when movement is detected at the camera, such as muting a microphone of the camera and cutting off capture of visual images by the camera module.

A method and system for supplying power at a voltage selected from a plurality of voltages. Power is initially received at a first voltage. Embodiments communicate with an AC adapter to get device identification and see if the AC adapter supports other voltages. If so, embodiments communicate with the AC adapter to get more information about the adapter and identify what voltages the adapter is capable of providing. If one of the voltages would allow an information handling system to operate more efficiently, embodiments negotiate a power supply contract to operate at a second voltage. When the information handling system powers down, the system resets to operation at the initial voltage.

Systems and methods for backlight dimming via buck-boost conversion in an information handling system (IHS) are described. In some embodiments, an IHS may include an embedded controller (EC), and a memory coupled to the EC, the memory having program instructions stored thereon that, upon execution, cause the EC to: determine a characteristic of a display having a backlight; and dim the display by controlling a buck-boost converter to reduce a voltage applied to the backlight.

Backlight dimming via buck-boost conversion in an information handling system

A power adapter provides power to an information handling system. The power adapter includes a power supply and a power delivery controller. The power supply receives an alternating current (AC) input at one of a plurality of input voltages, and provides a direct current (DC) output at one of a plurality of output voltages, each output voltage being associated with a current limit. The power delivery controller determines, upon being plugged into an AC power source, a first input voltage of the AC power source, determines a DC power delivery capability of the information handling system, sets a first output voltage and a first current limit of the power supply DC output based upon the first input voltage and the DC power delivery capability, the first output voltage and the first current limit defining a first power limit to the information handling system, determines that the power supply can provide a second power limit that is greater than the first power limit based upon an operating condition of the power supply, and communicates the second power limit to the information handling system.

System performance using optimal adapter efficiency

A cooling system for an information handling system in a portable chassis comprises a fan housing containing two counterrotating impellers, wherein the axes of rotation of the two impellers are aligned with an axis of orientation relative to a rear surface of the portable chassis. By changing the angle of the axis of orientation, impellers with larger diameters may be positioned in the same fan area for increased volumetric airflow. The shape of the fan housing, the diameter of each impeller and the angle of the axis of orientation may be selected to direct and distribute a greater volumetric airflow for improved cooling of components in the portable chassis.

A disclosed information handling system is coupled to a power adapter that is coupled to an AC line power source. The system includes an embedded controller storing instructions executable to determine that a trigger condition for limiting electrical power drawn by the system from the power adapter is met and, in response to the determination and in accordance with a low power operating mode, to limit electrical power drawn from the power adapter by the system to an amount less than or equal to the lesser of a power rating of the power adapter and a capacity of the AC line power source to supply electrical power. Limiting the electrical power drawn from the power adapter may include limiting the electrical power consumed by operation of the system or limiting a rate at which an internal battery of the system is charged by electrical power supplied by the power adapter.

Optimization of low power states while AC line power availability is limited

A high-performance single barrel power connector for receiving electric power may be capable of receiving more than 330 W up to approximately 600 W of power. The V+ pin and V&#x2212; pin may each be configured with a large plurality of contact points for connecting to a power plug. A connector body retaining the V+ pin and V&#x2212; pin may configured with openings to expose more of the V+ pin and V&#x2212; pin to air and allow the V+ pin and V&#x2212; pin to extend out of the power connector for convective and conductive heat transfer. A shell having a high thermal conductivity may be connected to the V&#x2212; pin and V&#x2212; pin and further connected to a bracket for increased heat transfer away from the V+ and V&#x2212; pins.

The present disclosure provides embodiments of direct current (DC) power connectors and methods to manufacture the same. More specifically, the present disclosure provides a connector plug with improved power capacity and structural rigidity. The connector plug includes an inner body and an outer body coupled to transmit power through the DC power connector, wherein the inner body is concentrically arranged within the outer body, and an insulating barrel that is coupled between the inner body and the outer body to electrically isolate the inner body from the outer body. The inner body and outer body comprise a base metal or metal alloy having an electrical conductivity ranging between 30% International Annealed Copper Standard (IACS) and greater than or equal to 99% IACS. In addition, the inner body, outer body and insulating barrel comprise an inter-locking feature, which increases the structural rigidity of the connector plug and prevents disassembly when the inner body, outer body and insulated barrel are assembled together.
