A:Answer No. There is an LED button, but any time it sleeps for any amount of time those lights come right back on and it's incredibly annoying.
They shipped it with SignalRGB, which annoyingly you have to trick into displaying black to "simulate" turning off, but SignalRGB broke after my first major driver update and now I'm stuck with a button that I have to constantly press and *no* software that affects it.
Who wants this garbage? Just let me have a switch to permanently shut it off. Jesus christ, I'm not an e-girl or a twitch streamer, why would I want this stupid garbage?
