Thanks for the info! Disabling deep sleep in S5 in the southbridge didn£™t work initially but the support team sent me a new BIOS revision (3.70B) which did successfully disable deep sleep in S5. Now the header powers off with the system. Works perfectly!

Really appreciate the help.]]> Sat, 27 Mar 2021 09:23:34 +0000 https://forum.asrock.com/forum_posts.asp?TID=18345&PID=84947&title=deskmini-a300-usb-header-power-off-on-shutdownpound#84947 https://forum.asrock.com/forum_posts.asp?TID=18345&PID=84702&title=deskmini-a300-usb-header-power-off-on-shutdownpound#84702 Author: ASRock_TSD

Dear Kurokaze,

Thanks for posting!

Please adjust the following settings to disable the USB power once the system shuts down.
Advanced\South Bridge Configuration\Deep Sleep\Enabled in S4 & S5.

Please make sure to press the F10 button to save the changes.

If it does not work, please uncheck the following setting in the Win10.
Control Panel/Hardware and Sound/Power Options/System Settings/Turn on fast startup/uncheck

With thanks,
ASRock TSD

Hello,

Wondering if anyone has found a way to turn off power to the USB 2.0 header on the A300 motherboard when the system is shut down£ I have the deskmini argb strip connected through this and the strip stays lit when the system is powered off. Enabling deep sleep for s4/s5 in the southbridge in UEFI had no effect; the header stays powered on.

Thanks in advance!]]> Sat, 13 Mar 2021 09:53:11 +0000 https://forum.asrock.com/forum_posts.asp?TID=18345&PID=84615&title=deskmini-a300-usb-header-power-off-on-shutdownpound#84615
