Abstract: Techniques are described for adaptive device power management. The device interface application of a hardware computing unit detects a launch of an application by the operating system (OS) to be executed on the hardware computing unit, in an implementation. The device interface application identifies the launched application and determines whether a hardware profile exists that is associated with the application. The hardware profile includes one or more hardware parameters that yield the optimal performance for power consumption by the hardware computing unit when executing the launched application. Based on determining that the hardware profile exists, the power policy of the OS is updated for the launched application, and thereby, the driver updates the power state(s) of the hardware computing unit based on the new power policy.

Abstract: Power management in a computing device. A driver is registered with an operating system (OS) executing on the computing device to receive information about a position of a user interface control. If the user interface control is moved, the driver receives a notification of the user interface control position and determines a power management intervention based on the position The driver transmits the power management intervention to power control circuitry which sets a power setting of the computing device based on the intervention.
