    Author of this topic ask about password and how to recover it. Seems he made a post in wrong part of forum, as he didn't made bios request, but password removal help.
    I continue discussion of how to remove password.
    I didn't upload bios file at all, so i think this is missunderstanding.
    This topic is about Lenovo Thinkpad L15 Supervisor Password removal, if your request is about this model OK, if not you are off topic here, that's why you must provide the data I've asked for as per the rules.

      Please help with connection of RT809H.
      With auto-ISP it shall connect without problem?

      RST cable shall be connected?
      There is somwere 10K resistor to switch to able programming?

      I made schematic fot ISP/JTAG, can someone confirm?
      reupload with small image

          I am able to read the EC for L15 Gen1 with SVOD4. Can someone assist me on how to remove supervisor password. I have tried yoga x390 (x13 to confirme )nuvoton npce288/388 sv password removal guide with svod4 and it did not work for me.

          Attached is my EC dump.

              Is there any way to read the EC for this model my friends using the RT809H?

                hoaca388, tried your file and it's still not working. Now I am not able to power up the laptop. I have verified that I do have power.

                  ymifdal, I am not familiar with RT809H. If your RT809H software support NUVOTON chips, and the programmer support 1.8V and I don't see why RT809H cannot read/write. Just map the RT809H pins to keyboard pins.

                    Anyone know if there is an instruction how to removal supervisor password from EC dump for Lenovo L15 Gen1?

                      rbvndonh already matched the pins I guess in post # 78
                      All is remaining is locating the pull up resistor to be able to test read/write

                        If the pull up resistor is in question I would look at the NUVOTON chip specs and other programmers specs to see their requirement to perform read/write. I know there is a lot of research/homework that need to be done here unless someone here at the Badcaps.net have a solution for you.

                            I tried to comminicate, but RY809h don't have this chip in list of available chips. Auto dont work, so maybe resistor switch is required.

                            I think buying RT809H instead of SVOD was one of my biggest fault lat years.

                                  They are from offset when you read the EC file by a hexadecimal program like HxD . so you need to clear between those numbers.

                                      hi,
                                      i have a locked T14 gen1. Serial number can't be read unfortunately(the sticker is torn) , i don't know what details to give you in such case, except the board is NM-C631.
                                      I managed to read the Nuvoton NPCE68 with SVOD4, i attach the file.
                                      I tried to remove the password by comparing with the file for SSDD that MAXpower3 gave.
                                      Now it gives me "bad SVP data" error and shuts down. I also attach the file i modified.
                                      Please help me
                                      Later edit: i also modify only the areas that Maxpower mentioned (3C420 to 3C45F and 3D420 to 3D45F) and also, BAD SVP.
