In terms of removing a BIOS password you have forgotten -- NO, there is no way to do that.. That's why it is very important to write down such passwords.
HP does not reset passwords on existing motherboards; instead, they require the replacement of the entire motherboard because the BIOS password is encoded into a chip soldered to the motherboard, and since that chip is not replaceable, their policy is to replace the entire board.
This is VERY expensive and, even if they agree to do it, which they likely will NOT, it will cost more than simply replacing the laptop.
