SYSTEMS AND METHODS FOR HOT PLUG GPU POWER CONTROL

摘要

Systems and methods include an electronic device having multiple GPUs and a GPU power control process that controls switching between a first GPU and a second GPU, such as a high performance GPU. The electronic device uses the first GPU when an external device is coupled to an adapter connected to the electronic device.
