Hello, guys! // Comment: If you need any help, just post your native DSDT along with an existing rehabman patch, if it exists. Otherwise, I'll try to patch it from scratch. If you want me to implement it properly, post your EFI folder aswell. I will help as many people as possible! My...

@Feartech Thanks for the quick reply. I will go through it and let you know my result. Thank you once again.

@Feartech I've followed the guide you suggested and created a SSDT-BATT. But my battery still stuck at 1% and status is not getting updated. I'm attaching my updated PR zip. It would be great if you can have a look at it and share your thoughts on it. Thank you.

Yes, indeed. We are trying various methods to fix the issue. Still my battery hesitates to open up. It's under serious trauma that I installed MacOS in my machine, and it had to leave its beloved companions Windows and Linux. I need to counsel more

I made a patch for my HP ProBook 430 G6. Seems to be working normally, haven't tested extensively yet though. Here it is in case anyone is interested:

EDIT: patch currently has a bug where the "estimated time remaining" isn't calculated and you get somewhat frequent "low battery" warnings. Charge % seems to be accurate though and it's just mildlly annoying. I'll update this when I find a fix.
EDIT 2: the above issue was caused by having EC0 -> EC patch on Clover. Disabling it and using SSDT-EC seems to have fixed it.
EDIT 3: It wasn't actually fixed (though the warnings seem less frequent). I'll investigate further.

@anor4k, hi there!
have you managed to fix those "low battery warnings"? I've got the same warings on HP 440 G6 and they are quite annoying )))

 

[e285ne]

@anor4k, I've applied your patch and cleared nvram and it seems everything works like a charm now, I've had two full discharge cycles and the "low battery warning" hasn't appeared

Hi, I need your help with battery patch

HP Probook 440 G6

Here's the situation:
I've patched the DSDT and got the battery indicator which shows right amount of charge (booted to linux and compared the remaining charge). Furthermore - sometimes it shows the remaining time of charge/discharge!
But then all of a sudden something clicks in it and it gives a warning of low battery level and stops showing the remaining time (thought it still shows the remaining charge)

I suppose the problem is in patch I've applied.
I took it from here https://www.tonymacx86.com/threads/...g-battery-status.116102/page-500#post-2021126 thanks to @anor4k I've got the battery working though a bit limited

What I've tried so far - installed debug version of VirtualSMC, enabled debug (-sbatdbg in boot_arg) and tired to view logs like this

log show --last boot --predicate 'sender="Lilu" and eventMessage contains "SMCBattery"'

But I do not see any errors and I'm stuck
Please help me with this
I can provide any info (EFI, logs etc.)
