I’ve been using Manjaro for a good long while and currently I keep a Windows install just to control the battery, since I’m Windows 10 I used Lenovo’s Vantage to control the thresholds. I’m hoping one day to remove Windows since I don’t boot into it anymore outside of battery reasons.
The thresholds themselves still work on Linux but I have no way of controlling them, so far I have to reboot each time I want to adjust them, like if I need to charge them further.
I’ve looked at various tools in the Arch wiki like TPL and TP_Smapi, which didn’t show up when I tried the normal Pacman -S Command and the AUR package didn’t work, when I set it with TLP it didn’t seem to make any difference.
Two theories I have is either Vantage overrides TLP and conflicts, or the T420 is too old for TLP and can’t use the thresholds, I did testing where I turn the thresholds off but that didn’t appear to make a difference, it would charge up but it would go past the thresholds no matter what.
If anyone has any advice on how I can get the battery control working under Manjaro i’d appreciate that, or even confirmation if it really is too old to use these, since the T420’s fairly old. I don’t want to remove Windows without getting it settled in case I need to recharge the batteries or if some driver gets stuck.
