Battery Not Working on HP AU620TX Laptop

[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. But again when I remove the power cord, it starts lowering

maybe try with abm_firstpolldelay boot arguments:

GitHub - RehabMan/OS-X-ACPI-Battery-Driver: Implements an Advanced Configuration and Power Interface (ACPI) based battery manager kernel extension (kext/driver) for non-Apple laptops running OS X.

have you tried a EC reset on your laptop?

Yes I have tried EC Reset

Yes I have tried EC Reset

maybe try VirtualSMC (remove FakeSMC)

and SMCBatteryManager (remove ACPIBattery)

as some laptops don't need acpi patching with those (mine didn't) although we have different machines.....
