Hello, so I know that most boards these days send power even though the rest of the computer is turned off. This is often called "ErP"

With previous systems I would disable this feature to ensure that my USB microphone and my power LED would turn off once I shut down the computer. (my power LED is unique since my system is built inside a PowerMac G5 case with a modified front panel.My powerLED is a modified G5 PoweMac front panel that functions using a special cable that functions like this: https://imgur.com/a/eLw5tCg . The cable uses the + pins for the power switch and front panel LED.)

With my ASRock B450M Pro4 however, I can't seem to find any ErP settings. I know that the "Deep Sleep" setting in the BIOS is supposed to do what I want, however even with Deep Sleep enabled, my Mic and power LED remain lit after shutting down.

If anyone knows how I can disable ErP support, or a setting that will make the power LED turn off at shutdown, I would be extremely appreciative. ]]> Thu, 21 Feb 2019 15:43:14 +0000 https://forum.asrock.com/forum_posts.asp?TID=10933&PID=60860&title=disabling-erp-support-on-b450m-pro4#60860
