I understand that I need the original bios file patched and follow the instructions on this post:

Need to
Remove all battery and CMOS battery
press F1 to enter setup: password 1234
wait 20sec or more.
with the patched bios file written on the eprom chip right? Not with the original.

Yes
with new patched bios file

The patched file needs to be made from the original, I can't use the one from the post right?

So after pressing F1 and entering password 1234 I get this message but the laptop doesn't stay on after displaying the message, shuts down after 3 seconds and the hardware ID gets reset a new one will appear after retrying. All of this without any battery as motioned in the instructions. I don't have the original charger I have the laptop plugged with an USB C + and - to the power supply. If I plug the battery still the same (no bios battery plugged). Any idea why?

I understand that a Lenovo auto-patcher exists, tried it but I can't open the cmd command on my pc. Here is the link :

LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal - Badcaps

lenovo_autopatcher_0.2.zip (https://www.badcaps.net/filedata/fetch?id=2224617) Hello everyone! In the past several weeks I've learned a lot from this forum and its community especially from all the folks who contributed to THIS (https://www.badcaps.net/forum/showthread.php?p=980956) thread...

Can you do that with my original bios? That's why I was asking if I can use that file in the post because it seams that I need to create one from the original.
