Description vmjizkya4 2025-05-13 12:35:35 UTC
I have a Lenovo Yoga 7 ARP8, my hw can support the charge limit, i already checked it on kde plasma and windows, in gnome 48 this feature didn't show up so i checked with this command: "upower --dump" and i saw that there isn't any line about "charge-threshold-supported:    yes or no " so a Gnome Dev suggested to me to open a bug in this thread.

Reproducible: Always
