Battery capacity decimated over night

[edp9]

Hi, this morning i woke up to my laptop battery being completely dead, then, when turning it on, it shoed me the error 601, saying that my battery's capacity went under 25% of it's designed capacity (designed was 41000mWh, now it's 7600mWh). Checking battery logs, i saw that yesterday it was completely fine, as it showed 30000mWh for an 83% charge; because of this i don't think that the battery actually managed to deteriorate that much just over night, and it's maybe a driver or windows issue.

05:38:27 Suspended   83 % 30.758 mWh

06:03:34 Suspended   67 % 24.602 mWh

14:54:54 Active AC 1 % 277 mWh

15:00:35 Suspended   5 % 1.779 mWh 1

5:01:10 Active AC 5 % 1.894 mWh

15:04:33 Suspended   7 % 2.599 mWh

15:05:48 Active AC 37 % 2.841 mWh

15:23:19 Battery changed AC 71 % 5.440 mWh

16:02:55 Report generated AC 87 % 6.653 mWh

You can also see that the charging was actually right for the first 7%, but degenerated after, with just a 240mWh increase for a 30% charge.

(it says battery changed because i randomly tried to uninstall ACPI battery drivers, but it didn't fix anything, i didn't actually change the battery.)

I'd love to know if there's a fix that doesn't involve removing the battery, as tis laptop isn't very easy to open.

Thanks for the help.
