BIOS password on a new laptop after purchase.

[manoyloilya2021]

• Hello. I encountered 1 problem on my laptop "Hp probook 640 g1" There was originally a password. But I didn’t know him, no contact with the seller.
• I have already tried methods like turning off the battery, etc. But nothing came of it.
• Whether there is a SMC.bin (If I'm not mistaken in the name) For my BIOS - laptop?

BIOS (and Power-On) passwords are encoded into the firmware on the motherboard and we have no access of any kind to that.

There is no MASTER BIOS password that works on all PCs or even on all HP PCs. That is an "urban legend" that is simply untrue. If there were such passwords, they would have been posted on the Internet and there would be no value in setting BIOS passwords.

Removing or replacing the BIOS chip does not reset the password, nor does removing the CMOS battery, nor does shorting out the CMOS battery leads.

HP policy is NOT to reset BIOS passwords on existing motherboards -- so changing such a password requires completely replacing the motherboard with a new one that does NOT have a password encoded into the firmware -- and that usually costs a LOT more than simply replacing the computer.
