by hopkokHi masters, I need your help.
I am working on Lenovo Legion 16ITHg6
Motherboard number NM-D721, no BV, no schematic but I am attaching very closes ones.
INPORTANT: My motherboard version is with IT8258 IC, that is controlling keyboard and RGB LEDs.
My problem is on UI142, +3VALW_AG is not stable, floating from 0V to 3,3V.
AGKB_PWR_EN_N signal is floating too (that is why+3VALW_AG not stable).
Power LED is not working as well, power button working well.
UI26 ??? is there any firmware too? Powered by +3VALW_AG.

Thanks!...-

I read SPI and extracted it8227 firmware from original BIOS...
