missing ACPIBatteryManager.kext from clover/kexts/other

then remove folder 10.10

config.plist:

enable these:
Code:
<key>Fixes</key>
            <dict>
                <key>Comment-IRQ Fix</key>
                <string>The following fixes may be needed for onboard audio/USB/etc</string>
                <key>FixTMR</key>
                <false/>
                <key>FixRTC</key>
                <false/>
                <key>FixIPIC</key>
                <false/>
                <key>FixHPET</key>
                <false/>
            </dict>

also from here:

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).

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

I have an Hp Omen ek00042tx laptop
Following are its main config:

I started reading up on the battery patching.
In my DSDT following is the entry for embeddedcontrol

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.
