Abstract: An information handling system detects an initial insertion of an alternating current (AC) adapter, and determines an identifier associated with the AC adapter. The system may also determine a parameter for attenuating noise generated by the AC adapter based on the identifier, and attenuate the noise generated by the AC adapter by applying the parameter.

Abstract: 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.

Abstract: A method for increasing power supply voltage in an information handling system in a normal mode with a first peak voltage comprises, in response to receiving a request for a higher peak voltage, an embedded controller (EC) receiving information associated with the application including a request for power at a higher peak voltage, a housekeeping IC communicating a signal to a PWM IC to increase voltage supplied to the information handling system to the higher peak voltage, the PWM IC converting from the PSU to the higher peak voltage and starting a timer with a defined time period. If no additional requests for operating at the higher peak voltage are received before the time period expires, the PWM IC communicates a signal that power will stop being supplied at the higher peak voltage, and the information handling system returns to operating in the normal mode at the first peak voltage.

Abstract: 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− 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− pin may configured with openings to expose more of the V+ pin and V− pin to air and allow the V+ pin and V− 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− pin and V− pin and further connected to a bracket for increased heat transfer away from the V+ and V− pins.

Abstract: A power adaptor for an information handling system may provide a higher power output level by monitoring a temperature inside a transformer of the power adaptor. When the transformer temperature is below a threshold below a rated temperature, the power adaptor may be allowed to operate at high power output levels. For example, a power adaptor rated for 45 Watts at 100 degrees Celsius may be allowed to operate at 65 Watts at 70 degrees Celsius. A feedback circuit may use transformer temperature information to determine when a power output level of the power adaptor may be adjusted to a higher level and then reconfigure the power adaptor to operate at the higher power output level.

Abstract: Systems and methods for controlling a power adaptor Light-Emitting Diode (LED) indicator are described. In some embodiments, a method may include: detecting a coupling of a power adaptor to a voltage source; setting a plurality of transistors in a first configuration, where the first configuration provides power an LED coupled to the power adaptor via a cable; detecting a de-coupling of the power adaptor from the voltage source; and setting the plurality of transistors in a second configuration, where the second configuration ceases to provide power to the LED.

Abstract: An information handling system receives power from a reversible power cable by selectively configuring outer pins to provide power or communication with a middle pin providing ground. A power manager of an information handling system embedded controller uses a low level of power input to determine which outer pin provides power and which provides communication, and then configures the connector to route power at a high level to the system charger for powering the information handling system.

Abstract: An example switchable power adapter may include power circuitry and an interface coupled to the power circuitry. An application-specific integrated circuit (ASIC) may be coupled to the power circuitry and the interface. The ASIC may be configured to receive a signal transmitted by an information handling system through the interface; determine whether a delay period within the signal satisfies a delay period condition; and cause the power circuitry to alter an output voltage level provided to the information handling system through the interface. The interface may comprise at least a Universal Serial Bus (USB) receptacle.
