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: Systems, apparatus, articles of manufacture, and methods are disclosed for power budgeting for computer peripherals with electronic devices. An example apparatus to budget power in an electronic device includes interface circuitry; machine readable instructions; and programmable circuitry to at least one of instantiate or execute the machine readable instructions to: detect a Type-C event associated with a computer peripheral; write a power level offset based on an assumed power contract for the computer peripheral during debounce time; obtain an actual power contract for the computer peripheral; and adjust the power level offset based on the actual power contract.

Abstract: Embodiments herein relate to a module which can be inserted into or removed from a computing device by a user. The module includes an input-output port which is configured for a desired specification, such as USB-A, USB-C, Thunderbolt, DisplayPort or HDMI. The port can be provided on an expansion card such as an M.2 card for communicating with a host platform. The host platform can communicate with different types of modules in a standardized way so that complexity and costs are reduced. In another aspect, with a dual port module, the host platform can concurrently send/receive power through one port and send/receive data from the other port.
