Yes this video will help: https://www.youtube.com/watch?v=IhRw7ePhLKs

Video is for an Ideapad but same principle applies for Legion, you will need to dump the contents of the BIOS chip.

When I turn on my laptop:

• The display backlight turns on, but the screen remains black. I can see that the backlight has power.
• The keyboard light turns on, and I can toggle it on and off using the backlight button.
• The fan spins for a second and then stops.
• After a while, even though the screen is still black, I can hear the Windows boot sound.

I have bought the CH341A Programmer and read the bios
here is the bios detail and uploaded the bios file i read

Hi Folks,

I have a Lenovo Legion Y540-15IRH that has a supervisor password set. I set this password, but the password that it is supposed to be is not working. Not sure if I set it to something else by mistake. I use the same password on multiple devices. I have a valid dump. I tried auto patcher and it fails. I used the LENV DMI decrypter and I do see the service tag in the dump. This laptop has a Mfg date of 2020/11/13. Can someone point me to a how to? Or is it easier to do a request and supply my dump?

Thank You.

Awesome! Apparently my first character did not take for some reason. Thank You! I wish I knew how it was retrieved.
