[Guide] How to patch DSDT for working battery status

[shubhambanekar]

Hello, after patching my HP Au620tx laptop with this DSDT patch (https://github.com/RehabMan/Laptop-DSDT-Patch/blob/master/battery/battery_HP-G6-2221ss.txt) and using ACPI Battery Manager kext the Percentage of battery is showing up in Catalina. The Percentage is valid, but after booting in Catalina, my battery settings break, and the Percentage gets stuck there; even in windows after plugging the AC Adapter, the battery percentage won't change. I have to press my laptop power button for 30 seconds when it is completely shut down. After logging in windows back again, the battery starts working, but when I log back into Catalina, the battery percentage gets stuck.
Help Please.

Update 1 :
Okay, So now I checked the registers in this patch (https://github.com/RehabMan/Laptop-DSDT-Patch/blob/master/battery/battery_HP-DV6-3165sf.txt), which match with my registers. I applied that patch, and now the Battery seems to be lowering when the AC power is disconnected, but again when I plug the AC adapter back in, it doesn't charge. It still displays Battery is not charging.

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.)

Ok I've fixed the problem and now I have fully working battery with remaining time and no annoying warnings!!

here it is:

[Guide] HP ProBook 430 G6 (Whiskey Lake)

hi I've fixed the remaining battery time (and those annoying warnings!) Though I have HP ProBook 440 G6 but it seems to be very similar with 430 Anyway be careful with the patch The bug (IMHO) is very funny you can spot it before you patch and have a laugh ) based on @anor4k work, thanks man...

Currently trying to patch the battery on my Huawei Matebook X Pro 2020 (i5-10210U).

I followed the guide but end up with a lot of "51037, 6126, syntax error, unexpected PARSEOP_CLOSE_PAREN, expecting PARSEOP_EXP_INDEX_LEFT" errors.

This is one example of the code in question:

If ((Arg0 == 0x02))
            {
                Local0 = ECRD (RefOf (B1B2(SN00,SN01)))
                BMB1 [0x03] = NTOC (Local0)
                BMB1 [0x02] = NTOC ((Local0 >> 0x04))
                BMB1 [One] = NTOC ((Local0 >> 0x08))
                BMB1 [Zero] = NTOC ((Local0 >> 0x0C))
                Return (BMB1) /* \_SB_.PCI0.LPCB.HWEC.ECBM.BMB1 */
            }

I read up on this and found another post by rehabman stating that RefOf does not work with B1B2. So where am I supposed to go from here?

Hi, RehabMan.

I have tried following your guide to fix the battery status of my Acer E5-573-54ZV but I didn't get success.

When i searched for 'embeddedcontrol' on my DSDT, as suggested, this is what i get:

OperationRegion (VERM, EmbeddedControl, Zero, 0xFF)
Field (VERM, ByteAcc, NoLock, Preserve)
{
    LNPS,   8
}

So i couldn't patch the DSDT and my battery status is not showing at all. I have already tried using your ACPIBatteryManager kext but it continues not showing battery status.

I will attach the files asked for problem reporting. Everything is working, I just can't get the battery status showing.

I hope you can help me. Thanks in advance!

Your EC region is similar to me. Considering it is already 8 bit, it will work out of the box without patching.
I'm using VirtualSMC with SMCBatteryManager.kext and it works out of the box.

Hi Everyone, i have tried patching too and cant get the battery status.

The PC is an HP Pavilion Power 15-cb028nl.

Searching for embeddedcontrol return so many thing, but those with more than 8 are these:

SMD0, 256,
BADC, 16,
BFCC, 16,
MCUR, 16,
MBRM, 16,
MBCV, 16,

i have tried to patch with battery_HP-Pavilion-n012tx.txt from the repo and get errors when compiling, then i tried to patch manualy but without result.

I attach my DSDT and the schreenshot of the errors(if can help), hope anyone can help me.
Thanks in advance.

Are you running on Clover or Opencore? I have the exact same on opencore . But I don't see Battery Status.
