MiniBook X N150 Keyboard Backlight Dead in BIOS - backlight stopped working

Hello Chuwi Support,
The keyboard backlight on my MiniBook X N150 has stopped working entirely. The keys remain dark even when I am inside the hardware BIOS menu, and the Fn shortcut keys do not toggle it back on.

My exact Serial Number is: ZMinBXHY4H241200243 [1]

Could you please provide a solution? Maybe the correct EC firmware / BIOS patch files matching this specific December 2024 manufacturing batch so I can flash and restore the keyboard illumination?

Thank you!
