CoreBook X (i5-8259U model) - battery not detected under linux

Hello there…

I bought about a week ago this model of laptop, aesthetically beautiful and according to several reviews I had found (but in hindsight I could not say whether related to the 7th generation Intel or the 8th, the one I took).

I did almost immediately a very clean dual boot, installing EndeavourOS (an arch-based)… everything goes without any problem or uncertainty, with the battery that lasts about half an hour more with linux but … it is not detected at all (so the use with linux has a range totally blind).

Does anyone have this same problem or know how to solve it?

I have same problem with Ubuntu 20.04

I guess there is no fix to this problem? I have the same issue.
