BAT0 missing from /power_supply. Battery indicator shows no battery availble

Hardware
1

A few days ago I restarted my Librem 14 and when it booted back up, the battery icon showed a red X in KDE plasma. Hovering over it displayed the message “no batteries available”. Listing the files in /sys/class/power_supply shows only AC when it used to show BAT0 as well. Since then I have tried looking at online solutions, reinstalled PureOS, and switched to a different Debian based distro (for more reasons that just trying to troubleshoot this). Any help is much appreciated.

I suggest re-seating the battery.

I am having exactly the same issue on my brand new Librem 14. Re-seating the battery did not help. Anything else I can try to fix this problem?

Thanks,

/sys/class/power_supply$ ls
