(SOLVED) ACPI ERRORS ON A T480S

[Hasodikis]

This is not a bug per se, because my machine is a T480S.
It' s initially based on another EFI on GitHub with my modifications.
However I am posting this in your repo since most of the SSDTS are yours ("Tyler").

So .......

1. At kernel log after each boot, I get these ACPI ERRORS:

The TTS error seems to come from a duplicate method between SSDT-Sleep.aml and SSDT-LED.aml. Strange thing is sleep works.
The OINI error is more confusing to me, since I cannot file any dublicate. The only mention of this method is in SSDT-INIT.aml.

I also get this:

I cannot explain this

SOLVING
PART 1:
After I lot of searching, trial and error, the OINI ACPI error is no more.
I changed the SSDT-INIT

FROM:
DefinitionBlock ("", "SSDT", 2, "tyler", "_INIT", 0x00001000)
{
External (SB.PCI0, DeviceObj)
External (SB.PCI0.RP09.INIT, MethodObj) // 0 Arguments
External (DPTF, FieldUnitObj)
External (HPTE, FieldUnitObj)
External (OSDW, MethodObj) // 0 Arguments
External (OSYS, FieldUnitObj)
External (WNTF, FieldUnitObj)
External (ZINI, MethodObj) // 0 Arguments

Scope (_SB.PCI0)
{
Method (OINI, 0, NotSerialized)
{
If (OSDW ())
{
Debug = "INIT: Set Variables..."
HPTE = Zero
WNTF = One
DPTF = Zero
OSYS = 0x07DF
}

ZINI ()
If ((OSDW () && CondRefOf (_SB.PCI0.RP09.INIT)))
{
_SB.PCI0.RP09.INIT ()
}
}
}
}

TO:
DefinitionBlock ("", "SSDT", 2, "T480", "INIT", 0x00001000)
{
External (SB.PCI0, DeviceObj)
External (DPTF, FieldUnitObj)
External (HPTE, FieldUnitObj)
External (OSYS, FieldUnitObj)
External (WNTF, FieldUnitObj)

Method (OINI, 0, NotSerialized)
{
If (_OSI ("Darwin"))
{
Debug = "Set Variables..."
HPTE = Zero
OSYS = 0x07DF
}
}
}

Is this correction valid?

PART 2
the _TTS ACPI Error disappears only when SSDT-SLEEP is disabled in OC/ACPI.

Sleep seems to work fine without this SSDT. In your docs you mention that this SSDT is for fixing sleep when dual booting with windows. If that ' s so, then on a single boot to mac os laptop, this SSDT is not necessary, correct?

The thing is every repo in github for a t480 or a t480s includes this SSDT in its configuration.

You can find my EFI here: https://github.com/Hasodikis/T480S-Hackintosh
I include an ACPI dump in my repo.

If you could help I would be grateful.
