Nvidia Optimus lights on/off like a christmas tree, any workaround ?
Dear forum readers,
I recently got a new MSI laptop (GP76 10UG). As is now usual with Nvidia-equipped hardware, this thing has Optimus. However, yet again, the dGPU switches on from time to time for no apparent reason. While it's not very often, it's still too much since I'm not using it, and the system should not be using it in my back.
I thought of deactivating the dGPU in the device manager, but the same happens as with my old computer in such a case, the dGPU remains on at all times. So, bad idea.
In addition to the random times when some process uses it in my back, the dGPU switches on when :
- I start the Task Manager
- I quit the Task Manager
- Sometimes (but not always) when I visit Settings => System => Display
- I log in
- I log out
- I lock my user session
- I unlock my user session
- The screen goes into power saving mode
- The screen leaves power saving mode
I want the system to not use the dGPU under any circumstances, unless I authorise it to, and the dGPU to remain off in the meantime. Is it even possible ? I can achieve this on Linux, but never did on Windows.
Fwiw, my Windows version is 20H2 (19042.867).
