Dell Vostro 3450 Advanced Options unlocking in progress

Oh wow I'm stupid. I forgot to include Windows 8 in Media Button initializer As soon as you press Support Center button ACPI.sys BSODS.
A workaround if the following:

Code:

        Device (MBT)
                {
                    Name (_HID, EisaId ("PNP0C32"))  // _HID: Hardware ID
                    Method (_STA, 0, NotSerialized)  // _STA: Status
                    {
                        If (LAnd (LGreaterEqual(OSYS, 0x07D6), LLessEqual (OSYS, 0x07DC))) // covers windows 2006,2009,2012
                        {
                            Return (0x0F)
                        }
                        Else
                        {
                            Return (0x00)
                        }
                    }
                    Method (GHID, 0, NotSerialized)
                    {
                        Return (Buffer (One)
                        {
                            0x02
                        })
                    }
                }

The _CST part I was talking about is the following:

Code:

Name (C1LH, Package (0x04)
        {
            ResourceTemplate ()
            {
                Register (FFixedHW,
                    0x01,               // Bit Width
                    0x02,               // Bit Offset
                    0x0000000000000000, // Address
                    ,)
            },

            One,
            One,
            0x03E8
        })

Dell had it 0x00 for width and offset for this C1 state.
