Hello guys!

Hi everyone,
I'm working on a Dell G15 5515 (Ryzen 7 5800H, RTX 3050 Ti) and recently installed a compatible 4-zone RGB keyboard and controller (for Dell G15 5510/5511/5515 models).

What I've Tried So Far:- Reseated the cables.
- Reinstalled AWCC and AlienFX services.
- Attempted BIOS downgrade but no improvement.
- Inspected ribbon cables for damage.
- Explored the possibility of BIOS or
