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...
www.badcaps.net
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.
