SOLVED Unable to Fix screen brightness control on Razer Blade 15 2020 Base

[hoaugtran]

Hello. I'm back to that damn error of not being able to control the screen brightness. I don't understand why I'm so unlucky that every time I switch to a new Laptop I alway have that error...
Here is my Laptop:

Model: Razer Blade 15 2020 Base
CPU: i7-10750H
iGPU: is it UHD630
dGPU: RX2060 ( I disabled it by SSDT )
SSD: Crucial P3 1TB

Here's what I tried :
- First, I used SSDTtime Tool to create SSDT-PNLF and PNLF to XNLF Rename Patch. But the brightness control doesn't work
- Next, I tried using the SSDT-PNLF prebuild from Opencore but that didn't work either
- From previous experience. I tried deleting SSDT-NoHybGfx.aml and replacing it with boot-args -wegnoigpu but the result is still the same
- I think problem due to SMBIOS so I also changed back and forth to SMBIOS MacBookPro16,3, MacBookPro16,1 and finally MacBookpro16,4 but not working

I really don't understand what the hell is wrong with my machine. I check DSDT.aml and see that have a Device name GFX0 but why SSDT-PNLF not work ( or is that GFX0 device just fake ? )


I don't know what the problem is. below is my config.plist at the Device Properties section:


And finally EFI and DSDT and also my ioregistry. If you guys know how to fix it, please help me. I'm sorry I've posted so many posts about Fixing brightness but I'm really helpless with it. I'm so unhappy. Thank you very much

As per the IOReg, the PNLF is loaded and active. Seems like you're trying to say, the Keyboard Brightness Hotkeys aren't working. Is that correct?
