An information handling system includes a power supply configured to provide a main power bus and a secondary power bus and a USB-C port. The USB-C port includes a connector that provides an internal power bus, an input selector that couples the internal power bus to the main power bus, and a controller that enables/disables the coupling of the internal power bus to the main power bus by the input selector, and selectively couple the secondary power bus to the internal power bus. The controller further determines that an over-voltage condition is exhibited on the first internal power bus, and, in response to determining the over-voltage condition, disables the first input selector from coupling the first internal power bus to the main power bus and uncouples the secondary power bus from the first internal power bus.

An information handling system sets, in response to a power event, a discrete graphics processing unit to transmit graphics data to an external display monitor and an internal display panel. In response to determining that a hybrid graphics mode is enabled and that a video driver has been loaded, the system switches a source of the graphics data to the internal display panel from the discrete graphics processing unit to an integrated graphics processing unit while keeping the discrete graphics processing unit to provide the graphics data to the external display monitor.

Managing power delivery, including receiving, at a first stage voltage regulator, an input power signal having a first voltage value; accessing a first table that indicates a correspondence between a parameter and voltage values of the input power signal; identifying a particular voltage value of the input power signal that is associated with the parameter; setting the voltage of the input power signal received by the first stage voltage regulator to the particular voltage value; accessing a second table indicating correspondence between the parameter and voltage values of an output voltage of an output power signal of the first stage voltage regulator; identifying a specific voltage value of the output voltage associated with parameter; setting the voltage of the output power signal output by the first stage voltage regulator to the specific voltage value; providing, by the first stage voltage regulator, the output power signal to second stage voltage regulators.

A variable height fan of an information handling system includes a first fan having a first hub and a first plurality of fan blades. A second fan impeller includes a second hub and a second plurality of fan blades. The first hub slides along the second hub as the variable height fan transitions between an expanded position and a collapsed position. Interior edges of the first hub are in physical communication with exterior edges of the second hub, and the second fan impeller drives the first fan impeller through the physical communication between the interior edges of the first hub and the exterior edges of the second hub.

An information handling system includes a USB-C port, first and second processors, and a USB-C power delivery controller. The first processor couples to the USB-C port utilizing a first connection type. The second processor couples to the USB-C port utilizing a second connection type. The USB-C power delivery controller includes first registers associated with the first processor and second registers associated with the second processor. The first processor utilizes the first registers to communicate with the USB-C port. The second processor utilizes the second registers to communicate with the USB-C port.

A variable fin stack for cooling components in a chassis of a portable information handling system. The variable fin stack comprises a first array of fins coupled to a first conduit and a second array of fins coupled to a second conduit. When the chassis is in a compact configuration for use in a mobile mode, fins in the second array of fins are positioned between fins in the first array of fins and the chassis maintains a form factor. When the chassis is in an expanded configuration for use in a workstation mode, the second array of fins is withdrawn from the first array of fins and the increased surface area provides increased cooling of components operating at higher power levels.

An information handling system includes a USB-C port and a USB-C power delivery controller. The USB-C power delivery controller includes connection preference information, and is configured to detect that a device has been plugged into the USB-C port, determine that the device supports a first connection type and a second connection type, determine that the first connection type has a higher connection priority than the second connection type, and establish a connection between the information handling system and the device utilizing the second connection type based upon the connection preference information.

Dynamic USB-C mode configuration

An information handling system may include a processor, a memory, and a power source; a base chassis including an outer cover surface; a variable height fan including: a main shaft including a cavity formed centrally within the main shaft; a first set of fan blades operatively coupled to the main shaft; a slide shaft placed within the cavity of the main shaft where the slide shaft is operatively coupled to the main shaft to rotate with the main shaft; a second set of fan blades operatively coupled to the slide shaft; a biasing member to bias the slide shaft to extend out of the main shaft; and a contact point prominence as a rotational point interface with the slide shaft operatively coupled to the outer cover surface.
