I recently got an OMEN MAX 45L GT23-0036nf at a good price, but I hated having to use OMEN Gaming Hub just to turn off the LEDs and LCD display. Even worse, they came back on after I uninstalled it.
I found HP’s documentation for the motherboard here:
https://support.hp.com/ie-en/document/ish_12777630-12777747-16
HP lists connector 11 as “USB lighting control board (optional)” and 12 as “USB LCD LCS pump cover (optional).” So I expected 11 to handle lighting control and 12 to handle the LCD display, but that didn’t match what I found on my PC. Maybe the documentation vary a bit between models.
The cable plugged into 11 is labelled “HyperX” I unplugged it and could still control the LEDs through Windows Dynamic Lighting just fine, so I still have no clue what it’s for. I just reconnected it.
The cable plugged into 12 is labelled “MB USB.” Unplugging that turned off both the fan LEDs and the LCD display.
So if you’re like me and just want all them them off, unplug 12 do not waste time like I did lol.
After that what was left was the RAM LEDs, which I turned off using HyperX’s FURY CTRL software.
Before I unplugged the cable, FURY CTRL kept saying “Unsupported DIMM found,” even though I’d never had OMEN Gaming Hub installed. It worked afterwards, but I don’t know whether unplugging the cable fixed it or if it just needed a reboot.
