    Re: Surface Laptop 3 Model 1868 Bios password

    @thatguycalledrob
    With the MS Surface Pro 3 and others the password can be recovered, so is sufficient to just obtain a partial BIOS dump using a software utility, then the password is recovered.
    For a MS Surface Laptop 3 you need to obtain a Full BIOS reading using a BIOS chip programmer, then the BIOS file is patched and this new file is programmed back to chip.

    As for the fptw64.exe utility don’t don’t if it has WRITE rights to the chip, otherwise it may work.

      Yeah I realised that first bit. So, what's the difference between A full bios reading and the output of fptw64.exe -BIOS -D?
      not trying to be thick, just know that I don't know

          Anyone know where I can get a clean copy of the BIOS firmware before I start taking apart my laptop?
          I followed links here, but was given an MSI which is junk when I extract it:

            Greetings to all!
            Please help. I have a Surface laptop 3 with a password on the bios.
            Please remove the bios password and clean the ME region (because my device has a touchscreen).
            I will be very grateful for the help as I do not know how to edit the bios myself yet.
            My device Surface laptop 3 1868( serial:001623203857)

              Please tell me, if I just replace the "Aword" and "SetOEMStrings" blocks with FF characters, will it help?

                    Re: Surface Laptop 3 Model 1868 Bios password

                    Thank you very much, with your bios the laptop runs and there is no password on the bios. But unfortunately neither the serial number nor the Windows key were saved. And because of that all the drivers are not installed.
                    I tried to take the original dump and change the ME region to the one in your file. But it took too long to turn on the laptop and the battery drained faster.
                    Is there any way to save all the notebook data and update the ME region?

                      Hey @peste - reckon I could use your attached .bin BIOS file with a CH341A programmer to flash my surface laptop?
