Thanks, my configuration does not have an discrete GPU so I never bothered to disable it. Have you compared power consumption when disabling the gpu in OC vs disabling it in bios?

I did not find the corresponding option in bios to turn off the mx250 gpu, I will test it when I found this option in bios. Could you give me a reference about how to disable gpu in bios?

Sorry, it appears that it's not possible to disable the dgpu in lenovo bios, I just assumed it was for some reason. I imagine it's possible to do so anyway by accessing the fields that are not shown in the lenovo bios but probably not worth the effort, so we can leave it at that.
