Thinkpad P16 Gen 3

[Alyosha2001]

@muede in real life, without the use of the dGPU, keyboard light off and monitor brightness to about 10%, around 7 hours. If you're not in a hurry, I've heard that Panther Lake is way more economic

When I set the BIOS settings  of my Thinkpad P16 Gen 3 to use my dedicated nVidia graphics card ONLY, my monitor switches to full brightness and the brightness controls of my laptop and Windows do not work anymore. Does anyone know how I can fix this?

I tried it and it works just fine, with the battery draining faster, as expected. Maybe it's the BIOS? I'm on 1.11

Yes that's a common issue with optimus laptops, reinstalling the current dispay output drivers (in your case dGPU drivers) should do the trick

Which version of the nvidia driver are you using. Do you have a download link to the version that works fine on yours?

Unfortunately, that did not solve it for me. I also got a thread at the Lenovo forums going about this, but no solutions yet that work.
