Really odd problem with battery

My battery was set to charge to 60% and for many months it worked fine. My machine is a Lenovo Legion 5 AMD/RTX3070.

cat /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode

So it is still (allegedly!) set. But it is charged currently to 100%.

Any ideas? Am going to run battery down and stick charger again, to see what happens.

My charge threshold always resets to 100 every time I plug the charger (Asus laptop) so I have to manually set it again

If this didn’t use to happen to you and now it suddenly does, that’s even weirder, I’m not sure what could be the cause

is windows also installed on your device?

I also have a Lenovo notebook, if I change the battery settings in the Lenovo software in windows, then they are adopted in EnOS.

Still got original windows install on a separate nvme, yes it is set there as well. Weird!

My suggestion would be to check your bios/uefi settings, mine has settings for always plugged etc
