ECEnabler VS WhateverGreen

Battery percentage - SMCBatteryManager,ECEnabler

Maybe adding EC-Enabler.kexthelps

ECEnabler (1.0.2)

As for not detecting the charger, your battery status probably isn't working properly. Have you tried ECEnabler?

Sounds like your battery stopped working properly under macOS. Maybe you could try ECEnabler? If that doesn't work, Dortania's OpenCore Post-Install guide has a section on fixing battery read-outs on laptops. (Why trackpad detection and battery status are so intertwined, I do not know.)

I have Monterey on my T530 working. I recently found ECenabler.kext, so now I don't need the Battery Hotpatch and renames any longer.

Have you tried the ECEnabler.kext? May help with your battery indicator. Best of luck.

try using this kext with virtualsmc and smcbatterymanager.kext

And finally, one last fix i needed to make all 3 screen working (before only 1 was working), was to replace the kexts with the newest version: https://github.com/acidanthera/WhateverGreen/releases

(from https://github.com/acidanthera/WhateverGreen/blob/master/Manual/FAQ.IntelHD.en.md)

Intel HD 520 graphics - WhateverGreen, AAPL,ig-platform-id = 00001B59 , device-id = 16590000

If so, refer yourself to Intel iGPU Patching guide and WhateverGreen patching manual.

I went to this site from the dortania opencore guide https://github.com/acidanthera/WhateverGreen/releases And I downloaded the 1.5.9 version I copy the kext file and I replace the old file with the new one in the kext folder.I have an amd gpu but I think there is hope.

Only other things I would check would be the BIOS settings. Otherwise you may need to work through the Frame buffer patching guide

Check this, there is more information about patching with whatevergreen.
