Sierra and later does NOT use /var/log/system.log for kernel logs.

No ideas unless you provide data showing what you're doing.

No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.
https://www.tonymacx86.com/threads/faq-read-first-laptop-frequent-questions.164990/

And note that you can get some detailed information on what ACPIBatteryManager.kext is seeing by installing the debug ACPIBatteryManager.kext.

Here. Since I am kinda lost on what I am actually doing/need to do, so I'll just post all the files.

I see no RMDT calls in _BIF, _BST, BTIF, BTST.
And you should probably start by analyzing the debug info from debug ACPIBatteryManager.kext.
Read the ACPI spec regarding _BIF/_BST so you understand the data that should be returned.

Can you show me how to do this step by step? I have been thinking the whole day but I still don't know how.

I did step 1, but I don't know where and how to read the ACPI spec regarding _BIF and _BST, can you show me how?
Sorry that I might be annoying, but this is the first time I actually debug something :<.

You can use google to find the ACPI specification.

Sorry for the late reply, today is my bday (Dec 6) so I'm quite busy.
And from the information that I have read, I see that _BIF should return information about the battery (model and such), and _BST should return status of the battery, correct?
