you may need:

  • add kernel flag "abm_firstpolldelay" to allow override of FirstPollDelay with simple kernel flag entry (config.plist/Boot/Arguments). For example, to set FirstPollDelay to 16000 (16 seconds), use abm_firstpolldelay=16000

All done. Move kext to other, enabled fixes in the config and added polldelay arg of 16 sec. Still showing the same (0% and more than half empty icon).
Trying to use ssdt batc.dsl, how to know battery code i am using ?

I am not able to find utilisation for the 16 bit and higher values in my dsdt except for references.
No Store related code. I have attached my dsdt for reference. can you tell me what is that I am missing.

FYI : my system is up and running except for battery indicator and trackpad left click which is a Synaptics trackpad I2C. Somwhere I read that in order to get trackpad working properly the battery needs to be patched.
I use OpenCore as bootloader.
