As per ACPI patching guide, DropOem must be set true with patched SSDTs in ACPI/patched.
You have it set false.
I didn't check anything else.

Problems:
- Using _OSI->XOSI patch without SSDT-XOSI.aml is not valid
- incorrect edits in SSDT-15 (not according to the guide)
- incorrect/strange edits in SSDT-16 too

Follow the instructions in post #1.

According to the ACPI patching guide you must set DropOem=true when you have patched SSDTs in ACPI/patched.
You have it set false.

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")...
