How to set battery charge thresholds on Thinkpad t440p?

Hello everyone.

My understanding is that this functionality is built into the kernel as of 5.17 and no additional modules are required. The battery charge thresholds should be available in /sys/class/power_supply/BAT0/charge_stop_threshold but… it’s simply not there.

I am running Silverblue 36 on a Thinkpad t440p. What am I missing here?

Hey @haralds

Have u done your first upgrade?

rpm-ostree upgrade?

v/r

Indeed, my installation is up-to-date.

uhh okay - I have to think about it - probably someone is faster than me to provide a solution :slight_smile:

Awesome, I look forward to your advice!

The files are now present in the BAT0 folder, but I cannot edit them even as root. I get a permission denied error.
