No idea about what you mean by "some problem".
All problem reports must have a detailed description of the problem.
Just saying "some problem" is not descriptive enough.

Files that needed for problem reporting attached in the previous post.

Your ioreg shows backlight control not implemented correctly.
See guide:
https://www.tonymacx86.com/threads/...rol-using-applebacklightinjector-kext.218222/

Also, your ACPI/patched is out of sync with native.
Note:
Code: 
SPEEDY-NUC:patched rehabman$ diff ../origin/ ../patched/|grep SystemMemory
<     OperationRegion (GNVS, SystemMemory, 0x6F125000, 0x05F5)
>     OperationRegion (GNVS, SystemMemory, 0x77128000, 0x05F5)
<                 OperationRegion (CPSB, SystemMemory, 0x6DCBCF18, 0x10)
>                 OperationRegion (CPSB, SystemMemory, 0x75CBFF18, 0x10)

I will use your guide for implement backlit control.
and about ACPI/patched, some one patched it for me and i dont have any knowledge about ACPI. if you have some free time please correct it for me, anyway thank you very much for your help and guide.

it's a good guide, but every time that I attempted to patch my dsdt/ssdts laptop performance was not so good. its seem that some experience with coding is needed for making a good ACPI patch:roll2:

If you have an issue (after following the guide carefully), upload "Problem Reporting" files as per FAQ.
 
ok. I will try again but at first, is it better to patch DSDT and SSDTs or only DSDT is enough?
