Welcome to the HP Support forum. Thank you for posting.
I think you talk about Windows login account password and not a BIOS password. Correct me if I am wrong.
There are not many things that could be done officially but you can definitely try to use all passwords you remember. If you use Microsoft online account (email) and not a local account, you can also try to enter the PC with previous and current passwords you remember, PC online and offline (connected/disconnected from the Internet).
