Abstract: Controlling power consumption at an IHS, including receiving electrical power associated with an initial voltage at a first time; determining that the IHS is to enter a low-power state, and in response: adjusting an UVP parameter for the electrical power from a first voltage to a second voltage, the second voltage less than the first voltage, the second voltage based on the low-power state; adjusting an OCP parameter for the electrical power from a first amperage to a second amperage, the second amperage less than the first amperage, the second amperage based on the low-power state; trimming the initial voltage of the electrical power to a trimmed voltage, the trimmed voltage less the initial voltage and greater than the second voltage; adjusting the power state of the IHS to the low-power state; receiving the electrical power having the trimmed voltage at a second time after the first time.

Abstract: Systems and methods for component population optimization are described. In some embodiments, an Information Handling System (IHS) may include a logic circuit and a memory coupled to the logic circuit, the memory having information stored thereon that, upon access by the logic circuit, enable the IHS to: identify a connector provided on a Printed Circuit Board (PCB), wherein the connector is configured to receive a device and to couple the device to a processor; and visually indicate a status of the connector.

Abstract: Systems and methods are provided that may be implemented to control operation of a power supply unit (PSU) during a low power state. The disclosed systems and methods may be implemented to control operation of a PSU relay included within the PSU, while the information handling system is operating in a low power state, e.g., such as the modern standby (S0ix) state. The disclosed systems and methods may also be implemented to provide intelligent PSU relay control that may be utilized to control operation of the PSU relay when the information handling system is entering, operating within, and exiting the modern standby (S0ix) state. This intelligent PSU relay control may include at least two operating modes: a modern standby mode and a normal mode of operation, and may be implemented to ensure that the PSU relay remains off during modern standby and returns to normal relay operation upon exiting modern standby.

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.
