Hi, I’m a Reddit refugee, mostly lurker there but one comment I made was useful to a few people so I don’t want it lost if/when I delete all my reddit data. I’m really hoping Lemmy gets a lot more active users and more content so I’m trying to do my (small) part:

I found that I need to wait 5-10 minutes after booting for the battery usage to drop to 4W. That might just be because of all the stuff I have running such as zfs - that’s another reason I originally thought 6-7W was the best I could do.

The key parts from my notes for the gpu:

• Set Prime Nvidia profile to intel gpu.

• Modify /etc/default/grub to have

GRUB_CMDLINE_LINUX_DEFAULT="acpi_osi="!Linux-Lenovo-NV-HDMI-Audio""

• update-grub2 and obviously reboot

The kernel option I found whilst researching what was stopping the gpu from going into power saving mode. I don’t have the link where I got it from right now. I had tried blacklisting the kernel modules for it but this made the power usage worse. It needs to be running, with intel gpu selected and the kernel option above.

BTW 3-4W is with screen brightness down (one up from darkest).
