    Thinkpad L14 G2 AMD (NM-D391) Power On / Supervisor password

    Hey,
    I just revived this motherboard (fixed no POST, thanks to a BIOS from this thread)

    Now there's a supervisor password required on power on. It is stored likely in EC, which is Nuvoton NPCE68BPA0DX (sometimes misspelled as NPCE688).

    I've seen some success on reading this chip in thread for Intel version of this laptop here.

    I have access to RT809H programmer. Is there any chance of programming this EC with it? If not I guess I need to find someone with vertyanov?

    Or maybe there's a way to bypass just power-on requirement by modifying main BIOS chip (Winbond 74M25JWEIQ, 32MB)?

                Have you used RT809h to read bios chip 74m25jweiq? what option have you used?

The problem is it is locked with a superviser password. Can anyone please give instructions on how to reset the bios or bypass the supervisor password? Thank you.

                    Thinkpad P14s Gen 4, BIOS Supervisor Password
                    by badzymandiaz
                    I have a laptop that was purchased second-hand, and I am able to boot Windows on and extract the BIOS dump (ONLY the BIOS region, I was unable to dump anything else due to an FCERR I received trying to dump the other regions) and use normally. However, because the BIOS is locked with a supervisor password, I am unable to use anything else except for Windows, and it has also disabled some hardware features of the laptop itself, such as the fingerprinting module, etc. that I really do wish to use.

                    I have been digging around for nearly 2 weeks trying to find any mention of the same model...

                    Thinkpad X380 Yoga supervisor password removal + Intel ME removal question
                    by Badpatch02
                    Hi all, I'm new here, a few words about myself: CS student, interested in hardware stuff too - tinkering my whole life but with practically no experience when it comes to firmware "hacking".

                    So I have this X380 Yoga with a supervisor password in place and before doing anything stupid I figured I'd rather ask.
                    I plan on using the tool from this thread: https://www.badcaps.net/forum/troubl...password-remov...

                    Hey guys,

                    have a laptop here that has a supervisor Password (dump in Attachements).
                    Before i write the Serial NR.etc i wanted to say that strangely after flashing with 3 different Bios dumps and one from lenovos site
                    the laptop works but everytime it wants me to type a supervisor password i never set.
                    I thought the supervisor password is stuck in the ec bios but no it isn't either because after replacing the ec chip from one of another board it still has the supervisor password.
                    Anyway i wanted to ask what of the two chips is the ec bios because on the left...
