You still have incorrect edits to _OFF In SSDT-14.
Key point: In your case, _OFF requires no edits!
Why are you changing it?

Hey Rehabman,

I have an other question about my DSDT. You know there is a patch called "Rename GFX0 to IGPU" as per guide.My DSDT accepts also Rename PCI0.GFX0 to PCI0.IGPU as well. If I use one these patches ''Rename-VID_AGP1 to IGPU'' this one also becomes acceptable by MaciAsl. So I am having a hard time to determine which patch I should use according to my DSDT. Thank you in advence!

Then just move on the to HGOF part which contains EC0 (SSDT-14). Cut that line only. Next thing is that to patch Rehabman Disable from _REG (DSDT). Find the patch section you just done patching and remove this line,

Code: 
External(\_SB.PCI0.PEG0.PEGP._OFF, MethodObj)\n
    \_SB.PCI0.PEG0.PEGP._OFF()\n

and then add your EC0 section that you cut before. (SSDT-14)

If you have accurate Sorted Order and Drop_Oem True , you should be done.

The changes you made to _INI are wrong.
You only need to call _OFF.
Remove the code you added that is calling \_SB.PCI0.RP09.PXSX._OFF()
The resulting _INI should be:
Code: 
        Method (_INI, 0, NotSerialized)  // _INI: Initialize
        {
            Store (Zero, \_SB.PCI0.RP09.PXSX._ADR)
            _OFF ()
        }

And again, you made incorrect changes to _OFF.
Correct _OFF is the original code:
Code: 
        Method (_OFF, 0, Serialized)  // _OFF: Power Off
        {
            Store (LCTL, ELCT)
            Store (VREG, VGAB)
            HGOF ()
            Return (Zero)
        }

Your profile is not filled out as per FAQ.
Please fix.

As to your question, use "Rename GFX0 to IGPU". It is the typical patch required. The others are for special laptops (such as Lenovo Thinkpad, which I don't think you have [even though you failed to fill out your profile])

I will do now.. I am actually using Lenovo Ideapad 510-15ISK. Does this matter?

Second, am I allow to share patched files (DSDT and SSDT-14) to give him a try?

Thank you!

It is not a Thinkpad. I wrote "such as Lenovo Thinkpad"...
Please remove your signature and place all data in the three profile fields as per FAQ.

You cannot share patched ACPI files.
You can read about the reasons in the guide:
