alt Hacker NewsBattery life optimization on Lenovos often involves installing and activating the correct GPU kernel module. My battery life on my P53 improved measurably after doing this, though installing new kernels involved a small build step. Are you just running with all the defaults?
I just installed cachyos normally and didn't do any tweak for GPU. The laptop just has an amd CPU and doesn't have a GPU. Do need a specific GPU kernel module for this?
