Could someone help me out here on how to turn off my mouse LED's after my PC has been shut down, please? I have an ASRock Z390 Phantom Gaming SLI/ac mobo. I don't have "Wake On Lan" enabled for mouse or keyboard. I don't want my cat turning my PC on while it covered with a towel (to keep dust off when not in use). I've tried enabling Deep Sleep option in CPU configuration in the UEFI. I've enabled CPU C4 - C5. I don't see C7. I've also plugged my mouse into a different USB port. Nothing works. I know if I turned the PSU off that'd do it, but that's also the quickest way to wear out a PSU switch too. I know there's got to be a way to do this. So, I don't care about charging devices while the PC is off. I just plug them directly into my surge suppressor. Thanks in advance.
