L14 Gen 2 Laptops (ThinkPad) - Type 20X2

[Keyvu73628]

Hello, is there anyone who would be able to help me locate and provide an image or guidance on where I can find the bios chip on the motherboard of the ThinkPad L14 gen 2 intel version and how I could remove the bios supervisor password.

I bought the ThinkPad used so no luck in getting any company help with the password so I want to flash it and remove the password if possible.

Note: I was being an idiot and reset CMOS resetting date and time on the laptop resulting in not being able to access the nvme drive with windows on it until I set time and date (which can't be done without typing in the supervisor password).

Thank you in advance.

post merged...next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread..

It didn't turn on with this firmware. With the original one, it does turn on, but I get an error with a melody. Thanks anyway.

[TecnoBond]

I need help, my machine was updating the software and it turned off and didn't turn on again.

How did you solve the problem reading NPC?

How did you solve the problem reading NPC?

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"

[Stefan Steff]

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