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!

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,

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.
