Battery stays on 92%

Hi all,

I am on Bspwm, and I just figured that battery is always on 92%, while my laptop is on charger.

Check your bios, perhaps it has enabled feature which doesn’t overcharge battery against some limit (it’s used to save battery lifespan on some laptops)

condition: 35.8/655.4 Wh (5.5%)

Jeez, i hope it’s reading mistake :sweat_smile:
Otherwise it means your battery is almost dead

Looks like bios / battery for that model is not it’s strongest part…


Is this a supermegagigapeta… battery?


I doubt that… because you can check my hardware report before 2 days : battery stats :slight_smile:

nah, something is wrong I think… check my previous post

Well then maybe your hardware is reporting wrong stats?


yes , but why ? :slight_smile: bad install or ? maybe I can change kernel ?

Easiest way to find out - run it from live USB and see if it’s the same behavior


I tried now with zen kernel :

>   serial: N/A charge: N/A status: N/A

seems good now…weird


Then report this to Kernel maintainers if it’s not known, and use LTS / zen :upside_down_face:


So is the problem solved then?
I found that on my laptop (MSI) the only way to change the battery max charge limit is through the manufacturer provided windows utility. No setting in BIOS (even when I activate the hidden settings). I have to dual boot in Windows, change the setting and then get back to doing my work in Linux, where the changes done in Window to the battery charging behaviour persist.

Yes, it is solved… I tried different kernel and everything is fine now :slight_smile:
