Do some debugging of _REG in the EC (it is likely the method that sets ECON).
Yes, I have read through these code and related explanations in ACPI specs. It should perform with no exception.

For EC Operation Region, Arg0 is 3 which is the ID for EC, and Arg1 = 1 means "connect the handler" to allow data access in the region. The args may be passed by OS as no other ssdts calls _REG. I wonder if the delay is related to system so only workaround might be applied.

Code:
            Method (_REG, 2, NotSerialized)  // _REG: Region Availability
            {
                If (LEqual (Arg0, 0x03))
                {
                    Store (Arg1, ECAV)
                }

                If (LAnd (LEqual (Arg0, 0x03), LEqual (Arg1, One)))
                {
                    If (LEqual (OSYS, 0x07D6))
                    {
                        Store (One, Local0)
                    }

                    If (LEqual (OSYS, 0x03E8))
                    {
                        Store (0x02, Local0)
                    }

                    If (LEqual (OSYS, 0x07D9))
                    {
                        Store (0x03, Local0)
                    }

                    If (LEqual (OSYS, 0x07DC))
                    {
                        Store (0x04, Local0)
                    }

                    If (LEqual (OSYS, 0x07DD))
                    {
                        Store (0x05, Local0)
                    }

                    If (LEqual (OSYS, 0x07DF))
                    {
                        Store (0x06, Local0)
                    }

                    Store (One, ECON)
                    If (LEqual (Acquire (LFCM, 0xA000), Zero))
                    {
                        Store (Local0, OSTY)
                        If (LEqual (LSTE, Zero))
                        {
                            Store (Zero, ^^^IGPU.CLID)
                        }

                        If (LEqual (LSTE, One))
                        {
                            Store (0x03, ^^^IGPU.CLID)
                        }

                        Store (LSTE, LIDS)
                        Release (LFCM)
                    }
                }
            }

I insert two names in EC and store Arg0 and Arg1 in _REG to them, the result is 0x3, 0x1, so the method itself seems working.

Code:
            Method (_REG, 2, NotSerialized)  // _REG: Region Availability
            {
                Store (Arg0, ESA0)
                Store (Arg1, ESA1)
                If (LEqual (Arg0, 0x03))
                {
                    Store (Arg1, ECAV)
                }

                If (LAnd (LEqual (Arg0, 0x03), LEqual (Arg1, One)))

No idea what you're referring to with "insert two names in EC".
You need to add RMDT calls to _REG to see if it executes beginning to end and stores the expected value in ECON.

Thank you, I had some misunderstanding related to that before and failed to watch the real process.

The method loops four time, the first two loops with Operation Region type 0 = SystemMemory, not 3 = EmbeddedControl.

Code:
            Name (LOOP, Zero)
            Method (_REG, 2, NotSerialized)  // _REG: Region Availability
            {
                \RMDT.P5 (LOOP, "Arg0", Arg0, "Arg1", Arg1)
                \RMDT.P3 (LOOP, "ECAV", ECAV)
                If (LEqual (Arg0, 0x03))
                {
                    Store (Arg1, ECAV)
                    \RMDT.P3 (LOOP, "ECAV Stored", ECAV)
                }

                If (LAnd (LEqual (Arg0, 0x03), LEqual (Arg1, One)))
                {
                    \RMDT.P2 (LOOP, "Loop 2 Passed")
                    If (LEqual (OSYS, 0x07D6))
                    {
                        Store (One, Local0)
                    }

                    If (LEqual (OSYS, 0x03E8))
                    {
                        Store (0x02, Local0)
                    }

                    If (LEqual (OSYS, 0x07D9))
                    {

                    }

                    If (LEqual (OSYS, 0x07DD))
                    {
                        Store (0x05, Local0)
                    }

                    If (LEqual (OSYS, 0x07DF))
                    {
                        Store (0x06, Local0)
                    }

                    \RMDT.P3 (LOOP, "Local0", Local0)

                    Store (One, ECON)
                    If (LEqual (Acquire (LFCM, 0xA000), Zero))
                    {
                        \RMDT.P2 (LOOP, "LFCM Pass")
                        Store (Local0, OSTY)
                        \RMDT.P3 (LOOP, "LSTE", LSTE)
                        If (LEqual (LSTE, Zero))
                        {
                            Store (Zero, ^^^IGPU.CLID)
                        }

Thank you, I had some misunderstanding related to that before and failed to watch the real process.

The method loops four time, the first two loops with Operation Region type 0 = SystemMemory, not 3 = EmbeddedControl.

Code:
            Name (LOOP, Zero)
            Method (_REG, 2, NotSerialized)  // _REG: Region Availability
            {
                \RMDT.P5 (LOOP, "Arg0", Arg0, "Arg1", Arg1)
                \RMDT.P3 (LOOP, "ECAV", ECAV)
                If (LEqual (Arg0, 0x03))
                {
                    Store (Arg1, ECAV)
                    \RMDT.P3 (LOOP, "ECAV Stored", ECAV)
                }

                If (LAnd (LEqual (Arg0, 0x03), LEqual (Arg1, One)))
                {
                    \RMDT.P2 (LOOP, "Loop 2 Passed")
                    If (LEqual (OSYS, 0x07D6))
                    {
                        Store (One, Local0)
                    }

                    If (LEqual (OSYS, 0x03E8))
                    {
                        Store (0x02, Local0)
                    }

                    If (LEqual (OSYS, 0x07D9))
                    {
                        Store (0x03, Local0)
                    }

                    If (LEqual (OSYS, 0x07DC))
                    {
                        Store (0x04, Local0)
                    }

                    If (LEqual (OSYS, 0x07DD))
                    {
                        Store (0x05, Local0)
                    }

                    If (LEqual (OSYS, 0x07DF))
                    {
                        Store (0x06, Local0)
                    }

                    \RMDT.P3 (LOOP, "Local0", Local0)
                    \RMDT.P3 (LOOP, "ECON", ECON)
                    Store (One, ECON)
                    If (LEqual (Acquire (LFCM, 0xA000), Zero))
                    {
                        \RMDT.P2 (LOOP, "LFCM Pass")
                        Store (Local0, OSTY)
                        \RMDT.P3 (LOOP, "LSTE", LSTE)
                        If (LEqual (LSTE, Zero))
                        {
                            Store (Zero, ^^^IGPU.CLID)
                        }

                        If (LEqual (LSTE, One))
                        {
                            Store (0x03, ^^^IGPU.CLID)
                        }

                        \RMDT.P3 (LOOP, "LIDS", LIDS)
                        Store (LSTE, LIDS)
                        Release (LFCM)
                    }
                }

                Increment (LOOP)
            }

Also, there's no ACPIDebug logs output when I removed the _STA fix. And ACPIPlatform also reports EmbeddedControl errors four times.

If _STA is accessing EC registers, it must be corrected/patched. The ACPI runtime in macOS/OS X does not allow EC access in _STA as it is called prior to _REG. This is per ACPI spec, even though Windows seems to allow it.

And if _STA for the EC fails to return the correct value, _REG will never be called as the device is simply ignored.

So... seems like the root of the issue is an incorrectly coded _STA.

Very interesting. I have a Miix 720 that I was going to sell after getting a Thinkpad 25. I might just keep it if it can be successfully hackintoshed.
