Hello.
Can someone give me a light here?
I have this Lenovo Thinkpad L14 Gen 2 20X2 with Computrance, and I'm trying to remove it.
I have tried different bios (both 16 and 32MB) that I found online. It turns on but it does not see any NVME, even after bios upgrade from Lenovo EXE file.
Anyone know how can I solve it?
Attached both original bios from machine and the new one that I have found online (both 16 and 32MB).

Thanks for your response!
With the files you uploaded I get orange light (charger present) and white light with a single beep for a second when I press the power button but no post.

With the ''found online'' file I sent, I get post, I can get into BIOS but it won't see any NVME (tried 3 different)

Hey everyone,

I''ve got lenovo l14 gen 2 with a 3 time blinking power button led, nothing else on the screen (there is visible backlight though)
I think that it may be a bios problem.
If someone could please help with it I would really appreciate it.
