How do I turn off the RGB of my PowerSpec G451?

PoofyFox

While it's not as big a deal when the lights are on, aside from extraneous power draw to run the RGB, I can't put my computer to sleep because the RGB stays on. It's a much dimmer light, yes, but I really shouldn't be able to navigate my room via light brighter than my phone at maximum dimness with a dark image on its screen allows. It makes actually sleeping quite hard.

Did some hunting online;

I've gone into the UEFI>Advanced>Advanced-Tab>Chipset Configuration>RGB-To-Disabled, but there's still RGB active. Set computer to turn off the fast-boot and shut-down and restarted a few times, no dice. Still active RGB. Set it to Deep Sleep in S5 (not entirely sure what it meant, but the reddit post I was following said that turned off their RGB), still no change. All the RGB is still functional as far as I can tell. Unless it literally turned off a single set of RGB that's buried in the stack of it somewhere. Heck, the "RGB color picker" thing under the Advanced UEFI shows "color: Disabled" as the option picked!

I'm pretty sure I'm missing something, but I don't know anywhere near enough about computer parts and their various manufacturers and such to know what it is.

Please help.
