Thank you for your help.
I read the article again and again, to determine what is missing. Unfortunately, there is no repair of the brightness problem.
Please allow me to say about my situation:
Before installing the patch, upgrade to 10.12.4 version after the brightness of the scroll bar, but can only be adjusted to the brightest and darkest.
After installing the patch, I have no scroll bar. Wake up after sleep will be directly black.
Maybe my notebook does not apply this.
Still no "Problem Reporting" files attached.
Read post #1, "Problem Reporting", and attach the files requested as per FAQ.

I realised I had not added SSDT-PNLF.aml to the sortedOrder. Once I added brightness started working.
Yes... If SortedOrder is specified, only those SSDTs will be loaded from ACPI/patched.
A file that is in ACPI/patched, but not in SortedOrder will not load...
It is as stated in post #1...

My brightness is working at max but no slider in preferences. Could you take a look?

You entered the AppleBacklight patch incorrectly.
You have empty MatchOS and MatchBuild properties in that patch, which means they never match any version/build, which is the same as having the patch disabled.
It appears you used Clover Configurator... always a mistake.
Use a plist editor to copy/paste the patch as recommended in post #1.

I just read that in another reply from you to someone else regarding the fcvo patch. It is working now, thanks for the heads up and I will keep that in mind!

Is there any way to get the smooth transitions from IntelBacklight.kext in the future?

IntelBacklight.kext does not work correctly with the current version of macOS (10.12.4).
I cannot predict the future.

Sorry, I always thought it was my mistake.

Need all files and output requested in "Problem Reporting".

But just commenting on your mistakes in EFI/Clover:
- the patch is entered incorrectly. Looks like you used Clover Configurator (read post #34 for details)
- ACPI/patched does not include SSDT-PNLF.aml
- even if ACPI/patched included SSDT-PNLF.aml, it is missing from config.plist/ACPI/SortedOrder

Suggest you go back and read post #1 again. Carefully.
