Hello. I bought a used HP EliteBook 820 G3. When I try to enter the BIOS, it asks for a BIOS Administrator Password. I do not know this password because I bought the laptop second-hand, and the previous owner did not provide it.

Hi:
Can you return the notebook?
If not, you will need to install a motherboard that does not have a BIOS password.
HP ceased providing SMC.bin files used to clear BIOS passwords from HP business class notebooks effective March 1, 2019.
The link below explains HP's policy regarding lost or forgotten BIOS passwords since that date:
HP Business PCs - Forgotten or lost BIOS password | HP® Support
There is no other way to clear a BIOS P/W from your notebook without the SMC.bin file.
Also, the HP Community forum rules of participation prohibit anyone from providing assistance with lost or forgotten BIOS passwords, not that we could have in your situation anyway (Rule 4.d).
