[Guide] Patching DSDT/SSDT for LAPTOP backlight control

Installed IntelBacklight.kext and rebooted. It stucks at apple logo! takes forever and never reaches to log in.

If you failed to rename IGPU to GFX0, it will take a while (could be 2 mins or more)
Or if you forgot to patch "Brightness Fix" (or config.plist/ACPI/DSDT/AddPNLF), it will also take a while.
And if you didn't implement graphics QE/CI correctly, it will also take a while.
And if you don't have an Intel IGPU, it will also take a while.

Your profile indicates Nvidia GT 525M only... no Intel IGPU... so why did you install IntelBacklight.kext that is only for 10.11.x and is only for systems with Intel IGPUs? (technically can be used on 10.12 prior to 10.12.4)

Is your profile accurate?

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.

you said this is for 10.12.4+?! thats why i followed.

No.
As per "IMPORTANT" in post #1, for 10.12.4 and later:
https://www.tonymacx86.com/threads/...ontrol-using-applebacklightfixup-kext.218222/

So now before i review your guide, how can i fix this freezing section?!

No idea. You didn't attach any problem reporting files.

Also, your profile is still incomplete. Missing screen resolution. Please read the FAQ carefully:

I tried all 2 methods to identify the brightness keys but none of them work. No keys seen in system.log. The same applies to Volume keys (tho it's working normally). What did I miss here?
Thanks in advance!
Edit: I'm doing it on my HP 15 Laptop (i3 4030u - Intel HD 4400, High Sierra)

After three days of trying,ı am still unable to fix brightness keys on my Lenovo 700.
I enabled it once,but when ı did a clean install because of problems,ı was hoping it would work as ı backuped up my clover.
But now it doesn't work whatever patch ı do.I am on Mojave.Without brightness fix and intelbcklight,which ı used,ı can use the backlight properly.
ProblemReportingFiles are attached.

Rehabman, can you look at my files when you are available?

Your ACPI setup is a mess.
