I did mean shutdown rather than turned off, yes.

No luck with the Good Night LED option; it stays on regardless of the setting. I'll bust out the tape I guess. Thanks.

Does anyone know the location of this setting?

Yes it is supplying power via the USB ports when the PC is shutdown. What you mean by "turned off", I don't know.

To remove power from the USB ports when the PC is Shutdown, the Good Night LED option in the Chipset Configuration screen is what you are looking for.

Also, tape is good for covering bright LEDs.
