Passwords simply can NOT be recovered; instead, they have to be reset.

We are not permitted to assist in resetting passwords because HP considers that a violation of customer privacy. HP can assist in resetting passwords but if your original warranty has expired, they will charge you for the assistance.
--------------------
For BIOS or power-on password resets, because the password is encoded onto a chip on the motherboard, replacement of that motherboard is required. For more information, read this HP thread: https://support.hp.com/us-en/document/c06368824.

If you are not prepared to spend the money to get HP to replace the motherboard, you would have to take the PC to a local repair facility to see if they can do it for you -- we can not assist in that in any way.
