The dump is 100% working (unlike what is on the network), 2 devices are working, clean ME, Boot Guard 0. At the first launch, we do not pay attention to the scary messages, we reset the system to factory defaults in the bios and the fear disappears. Good repairs to all!...

Here is all the info you should need to remove bios password from your same model or one with an MEC-Chip and also write back the config data

I can't say for 100%, but it seems that in this laptop the password is stored inside the MEC1723N and at the moment the only option to reset the password is to replace this chip.
