[solved] Lenovo Legion y520 issues

[RehabMan]

When I started this project iirc I used the Clover_v2.4k_r4423.RM-4614.cf0897a3.zip
You suggest using:Clover_v2.4k_r4444.RM-4652.c1f8602f.zip (released 2 days ago)

Your bootlog.txt proves you're using neither of those:

0:100  0:000  Starting Clover revision: 4428 on INSYDE Corp. EFI

Crap, you are right I believe I downloaded it from sound forge back then. Is the one I am using old?

This time I'll download it from your repository.

4428 is in between 4423 and 4444.
I have no experience with the code in 4428 as I never used it.

Good place to start.

To verify, I reckon I should download the latest version?
Clover_v2.4k_r4444.RM-4652.c1f8602f.pkg

That's what I would do.
You could always try 4423 as well if 4444 has the same problem, as maybe it is a regression introduced in versions later than 4423 and is still not fixed.
You'll find more about the problem as you test the various versions.

I will try out different versions.

Can you tell me the location where to check and verify if CPU PM works in IOREG?

Look under CPU0... X86PlatformPlugin should be loaded.
And you can look at SSDT-11.aml from your patchmatic output.
It should look something like this:

DefinitionBlock ("", "SSDT", 1, "PmRef", "CpuPm", 0x00003000)
{
    External (_PR_.CPU0, DeviceObj)    // Warning: Unknown object

    Scope (\_PR.CPU0)
    {
        Method (_DSM, 4, NotSerialized)  // _DSM: Device-Specific Method
        {
            If (LEqual (Arg2, Zero))
            {
                Return (Buffer (One)
                {
                     0x03                                           
                })
            }

            Return (Package (0x02)
            {
                "plugin-type", 
                One
            })
        }
    }
}

The code above is from r4444 running on my NUC6i7KYK, but the SSDT generated for Generate/PluginType=true would be the same for your laptop.

Note: By default my NUC guide does not use Generate/PluginType=true, but rather injects the _DSM method manually. But, for this test, I disabled the _DSM/manual method and enabled the Clover method.

Thanks, one more question before I start, since 4428 is now installed can I overwrite the install with the newer 4444 version and keep my current settings? ie config.plist, acpi>patched etc?

The Clover installer will not touch existing config.plist... nor will it do anything to ACPI/patched.

Ok, so I tried 4423 and 4444 and both didn't get CPU PM...

Currently loaded via 4423 (see attachment)
What else can I do to get it to work?

I changed SMbios to 14.3 though.
