For any other Librem 14 users running Qubes, I was able to install the librem-ec-acpi-dkms package in Qubes dom0, which lets you have more control over the embedded controller including setting charge thresholds. I documented my steps here: https://source.puri.sm/-/snippets/1170
@kyle what kernel are you on in dom0 - dkms complained about 5.4.125-1.fc25.qubes.x86_64. Looks like if I boot one of the older kernels it may work though.
@ajmartinez I think that's the kernel I used. The complaints I saw were warnings about it not being built for older kernels.
@ajmartinez After the dkms install it automatically loaded for me. Very odd. While I am using the very latest EC firmware on this, I doubt that's the reason.
@kyle yeah, a bit strange indeed. Not sure how much it matters this red hot second. Of course, I could back my stuff up and load clean again to see if that makes a difference. I’ve got plenty of machines available now!
