SSDT-PNLF UID99 and applbkl-name\applbkl-data

I've been trying to understand how to use these configurations for days, months. I'm looking for information in the kext reposity but I still don't see any light in the tunnel. In my HP630 Cpu Arrandale it runs 10.13 High Sierra, here the brightness control is broken and I can't get it to work. Navigating in total darkness I started doing test after test without ever arriving at any decent results. The problem is that I can NEVER see the brightness control bar unless I use the old Rehabman Kext, only in this case I can move the bar from one side to the other but without any effect. At this point I install El Capitan 10.11.6 and magically with the kext https://github.com/RehabMan/OS-X-Intel-Backlight everything works normally. At this point I'm trying to understand what this kext does and why it DOESN'T work on 10.13.6, hoping to be able to get to the cause of the bug. I attach ioreg facts with the same EFI configuration on 10.11 and 10.13 and the first thing I notice is that some values are different and I think this is the reason why rehabman's kext on 10.13 doesn't work.
