Thanks!, it works. IDK what the EC (Embedded Control) was, but I do a quick search on Chat-GPT explained very good even teach me how to modify hex data using hex editor programs.

Yes, indeed it's possible you have an LCD, Touchpad or RAM problem...from my "musical" experience with Lenovos
Good luck!

Same issue. Possible its not bios issue

the keyboard responds (caps lock indicator light).
if yes, start by disconnecting the battery and then disconnecting the screen from the motherboard.
test on an external screen

or use lenovo diagnostic for melody
