I’m not sure how the OS can cause this, I wouldn’t think it could, but I have 2 laptops (Lenovo K14 AMD, Lenovo T14 Gen1 AMD) that on both if I install OpenSUSE the battery drains when powered off. This has been ongoing for nearlya year on the T14 because I thought it was the laptops themselves had BIOS issues with it (T14 DID have this issue when it was first released but has since been fixed with a BIOS update, and the K14 is a 2022 model so I wouldn’t have been surprised if it had the issue). Doesn’t happen if I install EndeavourOS, Debian, or KDE Neon. Everything seems like it’s fully powering down when I do shutdown, no lights, no fans, no backlights, etc. But if I leave it in it’s bag for 2, 2 1/2 weeks, when I pull it out the battery will be <10% when I put it away at ~80%. Again, this ONLY happens if I have OpenSUSE installed. I’m honestly completely flummoxed where to even BEGIN troubleshooting beyond the fact that somehow it is OS related. I’m guessing it’s not fully shutting down properly, but…how would I be able to tell? Anyone have any ideas about how to troubleshoot this? I’ve really started liking Tumbleweed and would really prefer not to have to move away from it.
I currenlty have OpenSUSE on the T14 (K14 has been moved to Debian as it’s a bit newer and I need one of the 2 to work consistently).
Desktop is Plasma since I forgot to mention. Alos, although it shouldn’t matter, but on both machines I do use thresholds to keep the battery lifespan from degrading too rapidly. I have thresholds set to start charging @70% power, and to stop @95%. If this is of any use.
I suspect your battery logic does not work right in Tumbleweed.
I leave the default battery logic and have no issues after 5 days in the laptop bag.
Older batteries lie about how charged they are. I suspect your batteries are at end-of-life. Pretty much all laptop batteries last 3 years from date of manufacturing not the date of install.
A 3 year old “new” battery will probably last a year - then go downhill rather rapidly.
It is best to buy you next battery from a dealer that sells 100’s every month as he/she probably gets fresh batteries every 6 months.
I have replaced 100’s of laptop batteries since 1990 (I worked for NCR and HP). I pay a little more to get fresher batteries.
When the vendor refurbish laptops for resale stops refurbishing a model because newer laptop models come off lease - they might not get new batteries again for the model they no longer refurbish.
The K14 is literally a brand new machine that is a brand new model for 2022, it’s battery is, at MAX, ~10 months old, and in every OS the battery shows 100% life. The T14 battery is nearing 3 years old, however because of being used with thresholds, it still reports (on every OS) as having 98% of it’s lifespan remaining. Definitely not nearing end of life on either.Is there a way to fix OpenSUSE so battery logic works properly?
