Which part from post #1. ?

I use this..

- a single pre-built AppleBacklightInjector.kext
- a patch for AppleBacklight in config.plist/KernelAndKextPatches/KextsToPatch
- SSDT-PNLF.aml to activate the AppleBacklight kext

my screen looks like this one attached

The part involving EDID ProductID... is is the "Display ID dependencies" section.

Note: General rule is that you must read an entire guide to implement it correctly.

I have read the complete guide and i use the indicated information

If Clover can automatically detect your EDID, the easy fix is to change your config.plist such that Clover automatically injects a custom EDID with patched product-id. The product-id known to work is 0x9c7c. Just set config.plist/Graphics/EDID/Inject=true, and config.plist/Graphics/EDID/ProductID=0x9c7c.

I do not know what I'm doing wrong that's why I upload all the files
but thank you very much anyway i giv it up.

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.

SysPrefs->Displays should have a working slider for brightness.
Also check your setting for "adjust automatically"...

It may be that your laptop does not use the IGPU PWM for backlight control.
Such laptops (there are a few) do not work with AppleBacklight.kext.

As expected. Backlight to zero is a special case that actually turns off the signal to the panel.

Attach PR files from that scenario.

Hi everyone, so, on my Lenovo Yoga 510 I have tried everything to fix the brightness and still can't. I have a question, my Hackintosh looks like isn't recognizing the Built-in screen, but as a separated monitor, and I was wondering if it's what is causing the problem (please check the images, a image is just a exemple from the right configuration that I think I should have). Sorry for my English ;)
