USB ports will not turn off

nitewulf · 05 Feb 2020

I had this happen before on another build, but was able to fix the problem. This time, on a new build, I cannot get the usb ports to shut down when shutting off the PC. I have tried every suggestion I could find including disable fast startup, disabling selective USB suspension, making sure the USB root hubs are set to allow the computer to turn off the ports to save power. I don't know what else I can check or do and have exhausted all tutorials I could find. Motherboard is an Asrock Z390 Phantom.
Do I have to change something in the bios?

really, the only way to completely shut USB ports off would have to be through the BIOS. All that other stuff you did has proven futile as evidenced.

With that, I have to ask how you did that with your other machine but can't seem to figure it out on the new one?

Different system, I know, but this is what I would do to disable the USB 3.1 PowerShare ports. These are the ones that remain hot when the system is off, but still connected to AC. Used for charging phones, etc.

It is in the BIOS. These would be MY instructions, but something very similar in yours. Just have to poke and look for it or consult the MB/BIOS manual.

Enabling USB PowerShare on your Alienware system

PowerShare must be enabled at the BIOS. To enable PowerShare do the following:

Turn on the system
Tap repeatedly the F2 key as soon as you turn on the system
Go to the Advanced tab
Select USB PowerShare from the list and press Enter
Select Enable and press Enter
Press F10 to save and exit

Different BIOS as well as I can tell you I have no such feature (USB PowerShare) on my Gigabyte Z390 Aorus Xtreme (F8 BIOS) MB.

I might have changed something in the bios, but I can't remember. I'll check it tomorrow and see if there's any setting that might help.

I emailed Asrock and this is their reply.

"Please Enable the Deep Sleep setting in BIOS, Advanced, Chipset Configuration, On/Off Play [Disable] and Deep Sleep [Enable S4/S5] or [Enable].
Also adjust the shutdown behavior OS to retry.
Note: It shown Windows 8 but it’s also applied to Windows 10"
