[Guide] Patching DSDT/SSDT for LAPTOP backlight control

Here is the files

Your DSDT has no "Brightness Fix" applied.
FYI... You could easily add it with config.plist/ACPI/DSDT/Fixes/AddPNLF=true
Also, you will need to install IntelBacklight.kext (not ACPIBacklight.kext.. ACPIBacklight.kext requires a different patch).
No ACPIBacklight.kext installed anyway...

Also, if you plan to upgrade to Sierra or later, you will need to do something completely different.

Also...
Your kextcache output proves kexts are not installed correctly.
All kexts you need must be installed to the system volume.

Use "Brightness Fix" + IntelBacklight.kext, as per guide.
Or set config.plist/ACPI/DSDT/AddPNLF=true (still +IntelBacklight.kext).

No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

Use the gen_debug.sh tool mentioned in the FAQ, that way it is less likely you'll omit something.
