I have a laptop (integrated intel and discrete Nvidia). Ideally, the discrete GPU should not be used since it uses twice as much power as anything else combined for light workloads. However, I can see that "System" process in task manager is waking up my Nvidia GPU once every few minutes to do a GPU 1 - Copy task that lasts a second. Any idea what might cause this?
Plugging and unplugging usb-a devices (GPU is directly connected to the USB-C/thunderbolt, but USB-a ports shouldn't have this behavior) also wake the GPU for a few seconds.
