Hello,

I got a Taichi x470 with Ryzon 2700x and latest Win 10 pro 64bit.

Energysave Mode doesn´t work like it should. After a view minutes the system get wake up by PCI Express-Stammport or LAN. I have check a view stuff and found that my bios settings seemst to be ignored by Windows 10.

In Bios under ACPI Conf -> PCIE Devices Power On -> disabled

WOL should be disabled now.

South Bridge Confguration -> WAN Radio -> disabled

Wifi Modul should be disabled

In Windows the Wifi is still in device manager and the system still get wake up by LAN.

I disabled in Devicemanager - Lan - Energysetiing the WOL options, but the system still get wake up.

I install the latest Intel Driver for the LAN, there are some more option in Devicemanager -Lan - Energy options. Setup everything there but system still get wakeup by PCI Express-Stammport.

The WIFI are also still there.

Are I missing something, or why does Windows ignore the Bios settings.
