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).

That was my case too...almost 10 minutes to read 256kb ...and weird content.

[volinakis]

In my case re-seating the 32x0.5mm flat cable on the KBC connector side solved the problem...happened on many Lenovos (even if 1st pin is beeping right!!!)
Tried for at least 6-7 times until I get the real reading...took approx. 1 minute to read 254kb flash.
The writing part take no time...a blink of an eye and get programmed.

thanks, I think for L14 gen2 is 384Kb (NPC68B) , mine took like 8 minutes to read 384Kb and all was "1F 1F"
