Hello!! 
After several years running KDE on my ThinkPad laptop, I’ve decided to try Gnome.
On my previous KDE installation, I had set the battery charge threshold to 79% with a native option.
I was looking for the same config in Gnome, when I realize that the battery already doesn’t charge over 79% without doing anything.
I know that this can be achieved with TLP, but this package isn’t installed by default.
Is there any hidden setting to adjust this?
Thank you very much!!
You can try the Battery Health Charging GNOME Shell Extension.
It’s also in the AUR (Arch User Repository) as gnome-shell-extension-battery-health-charging-git maintained by me.
I think tlp is installed by default, only the gui is not. At least on xfce.
That means the setting is hardware stored.
The setting is just a GUI wrapper over what the system provides. In this regard, execute:
$ ls /sys/class/power_supply/BAT0
and look for anything resembling threshold. I’m not sure what the name is in Thinkpad, but it’s quite commonly named charge_control_end_threshold. You can just echo under root or sudo tee the percentage number (without percent symbol) you want it to stop charging.
Yes, I have found this extension searching in the forum, after installing I can modify the battery charge treshold, thank you very for your suggestion!!
I didn´t know that you’re maintaining it in AUR, I’m going to delete and install again your version.
Best regards!!
This is the output:
I can achieve what I want with the extension above mentioned.
Anyways, thank you very much for your help!!
Best regards!!
Nice, ThinkPad has both start and end threshold control. My Legion only has conservation mode whoch is a simple toggle, no way to set tbe percentage number, it’s hardcoded in the firmware.
