ErP Support determines whether to let the system consume less than 1W of power in S5 (shutdown) state. When the setting is enabled, the following four functions will become unavailable: PME Event Wake Up, Power On By Mouse, Power On By Keyboard, and Wake On LAN.redduc900 @overclockers.com
Enabling ErP if using a ErP compatible power supply has been the solution we have suggested multiple times here at ROG. Glad this worked for you.
for solving that "problem" enable ErP (S5) status and save.
after restart > return on BIOS and re-enable ROG LED options with your preferred color scheme/effect.
save and exit and GG.
