I have a razer deathadder elite chroma. Before when shutting down my pc, my razer mouse would also shut it's led down with it. But recently, everything i shutdown my pc the leds would still be on. I have checked my motherboard settings and both the options for keeping power on for usb is disabled. I even have turn of led when display turns off in razer synapse, but it only works when i got afk not when shutting down. I have a asrock z87 pro4 motherboard. sorry for bad english
