Thanks a lot.

> Can you check if the VPC2004 ACPI device has a method named "DYTC"?

If I'm understanding correctly, you're saying to check the disassembled ACPI
tables, right? The disassembled dsdt.dsl does appear to contain a DYTC method:

        Device (VPC0)
        {
            Name (_HID, "VPC2004")  // _HID: Hardware ID
            Name (_UID, Zero)  // _UID: Unique ID
            Name (_VPC, Zero)
            Name (VPCD, Zero)
            Method (_STA, 0, NotSerialized)  // _STA: Status
            {
                Return (0x0F)
            }

            Method (DYTC, 1, Serialized)
            {
                ITSV = Zero
                ITSM = Zero
                Local0 = Zero
                Local1 = (Arg0 & 0x01FF)
                Local2 = (Arg0 & 0xFFFFFE00)
                Switch (Local1)
                {
                    Case (Zero)

         ....

I'll attach the full file, in case it is needed.
