Abstract: A power management scheme for USB systems. For Mobile systems that has re-timer, a handshake is used between power delivery (PD) controller, re-timer and embedded controller (EC) so that the PD controller can end higher wattage power contract on USB-C connector after TBT/USB4 link is in low power (CLd/U3) and during system low power transition allowing Dynamic Platform and Thermal Framework (DPTF) framework to boost CPU performance and enhance battery capacity respectively. The same solution can be extended to desktop segment to allow PD controller to lower the USB-C power contract with connected devices before switching to standby rail. For mobile systems that are without re-timer, a handshake is used between BIOS, PD controller and EC so that PD controller can end higher wattage power contract on USB-C connector after TBT/USB4 link is in low power (CLd/U3) and during system low power transition.

Abstract: Embodiments may include systems and methods for managing multiple ports of a computing interface. A computing device may include a connector with a power port and a data port. A connector manager may identify whether a port partner is coupled to the connector, identify an inquiry related to a status of the connector, where the inquiry may be received from a BIOS of the computing device. In addition, the connector manager may generate an indication of the status of the connector, and further transmit the indication of the status of the connector to the BIOS. A BIOS may identify that a data device coupled to the connector through a port partner is to be initialized, and further transmit to a connector manager an inquiry related to a status of the connector, before initializing the data device. Other embodiments may be described and/or claimed.

Abstract: Embodiments herein relate to a circuit which allows the re-use of an existing power supply units having main power rails and an auxiliary power rail, while supporting large memory configurations in a sleep state to avoid data loss. A processor determines whether a power requirement of memory modules in a computing device exceeds an available power of the auxiliary power rail. If this is the case, the processor asserts an override signal which is used by a logic circuit to force the power supply to remain on in the sleep state. A set of switches disconnect the main rails from other components which can be turned off in the sleep state. A select circuit selects one of the main rails to power the memory modules.
