I just upgraded my motherboard from the AORUS B450 Pro WiFi to the MAG B550 Tomahawk, and I'm looking for a “feature” that was a part of my old B450 board, but that I can't seem to find in my new B550. The AORUS board maintained a kind of “low-power mode” even after I shut down the computer, enabling me to do things like charge my mouse overnight. My new board doesn't seem to have this capability, or at least, I can't seem to find it in the BIOS. Does anyone here know their way around the MSI BIOS well enough to point me in the right direction?
It wouldn't be much of a problem, but when my computer is in sleep mode, the RGB on my RAM sticks stays fully lit. I know how to disable it, but it's not consistent, and often I have wake my computer right after putting it to sleep just to change the RAM RGB settings so that it shuts off when I put the computer to sleep.
I know this is such a minor complaint, but any help would be much appreciated.
@TSMichaelB Thanks for pointing me in what looks like the right direction! I checked, and ErP was disabled by default. I tried enabling and disabling it again, but that didn't seem to do anything. I guess where I'm confused is that this option says “ErP Ready” which made me wonder if there's another ErP setting somewhere. I wasn't able to find anything though.

@TSMikeW That was it. I first tried switching the first option from BIOS to OS, but that didn't solve my problem. Enabling "Resume by USB Device" appears to have solved it. I'm a little confused though as the description says "system wake up from S3/S4," but I guess that also includes providing USB power while in S5? I'm not complaining, but I wonder if it's an actual fix, or if that just happened to tangentially solve my problem.
Still, if anyone stumbles across this thread with the same problem I was having, here's a possible solution if you're using the MSI Click BIOS 5 build from 05/15/2020.
First, just wanted to say thank you for everyone that contributed to this thread - exceptionally helpful!
I have the same motherboard and the same issue. The observations/suggestions here are exactly the same for a new version of the Bios: A50, released in early 2021.
