[Guide] Disabling discrete graphics in dual-GPU laptops

check it out

Use ACPIDebug to check that _OFF/HGOF/etc are executing as you think they should.
It could be you're emulating the wrong version of Windows ("OS Check Fix")...

The _OFF and _INI are in DSDT.

_INI in scope _SB.PCI0.PEG0.PEGP:
Code:
        Method (_INI, 0, NotSerialized)  // _INI: Initialize
        {
            If (LNotEqual (SVID, 0xFFFFFFFF))
            {
                Store (Zero, NHDA)
                Sleep (0x32)
            }
        }

Read post #1, "Problem Reporting".
Note: You cannot call _OFF from _REG. It is quite clear in post #1.
