Tried searching all over the Internet for a solution to this to no avail.

ASUS N550JV laptop
Microsoft Windows 10 Home
Version 10.0.15063 Build 15063
Latest Windows Updates applied
BIOS version: American Megatrends inc. N550JV.208 which appears to be that latest available.

When I shutdown Windows 10. (Start --> Power Switch Icon --> 'Shut down') The USB ports will remained powered. For example, any External USB bus powered Hard disks attached will perpetually spin until unplugged. Any USB device with an indicator light, will still be lit.

Unticked the "Turn on Fast Startup (recommended)" setting under the power options as per common recommendation over the Internet, yet the USB ports will remained powered after shutting down this laptop

I've tried doing a full shutdown via the command prompt using "shutdown /s" yet the USB ports remained powered.

Already tried resetting Windows 10 to factory / default (though to address another problem of Intel Graphics Continually crashing and restarting - turned out to be a botched driver update)

Any suggestions / ideas to get the USB Ports to completely power down when I shutdown Windows on this laptop?

Is there a little thunderbolt icon on the port?

Several of my HP notebooks had this as an option for charging devices when the laptop was off. Not all the ports did it though. Do all of the ports stay powered?

Pretty sure my latest Asus does it too.

OK Cheers Cadman. Admittedly, neglected to mention that I went through the BIOS and couldn't see anything that resembled USB power or any other setting that may affect it. There were other options there for Fast Start, which I turned off, again to no effect.

The USB menu only had two options available to be changed
- Enable Legacy support
- Enable XHCI support

Couldn't see any section for Power options.

Will probably have to screen shot the BIOS menus... For some reason, the available settings (that were able to be changed) in the BIOS were rather thin on the ground in general (unless I entered into some cut down version of the BIOS?)
- I accessed the BIOS using the Windows Recovery options --> Advanced Startup --> Restart Now then selected the UEFI BIOS option.

Thanks! that indeed looks to be it! If I re plug the disk to the USB port on the other side (without the Thunderbolt icon), it doesn't stay on after shutdown. Seems the USB ports on the Left of the Laptop will remain on. I shall swap things around.

It's just a feature that's meant to let you use your laptop as a power bank.. Macs have been doing this for years and there isn't necessarily a way to turn it off. Most hard drives these days wouldn't remain spinning when they are not being accessed though. So if you want them off you have to unplug them

Check for Asus software, should be an option in there if you still want to turn it off

Also it will only be on if plugged in to power outlet and above certain battery level.

IIRC the powered when off USB host plugs are meant to be yellow, whereas USB3 are meant to be blue

I have seen this as of recent only on laptops and some mobos, On my older devices they all had bios settings to turn it on and off.
