Where are those located?

  The grey coin-sized CMOS battery is alongside the motherboard. I suggest you look at the many guides and videos, just search "removing BIOS password".

    That will work for sure? I'd have to really start taking things apart.

      Almost certainly yes. I have taken apart many laptops, it's usually not more than 5 minutes reading a guide/video and another 5-10 minutes of work.

      Check HP for the service manual for your laptop. This is generally a standard goal the manual will give steps for. Usually all you need is a screwdriver of the right size and a bit of guts to pull apart bits of plastic, though I find my confidence that I'm not destroying anything is greatly enhanced when I'm following the manual and have reasonable confidence all the screws are out properly.

      Not for sure. That trick is kinda old. I had a Pentium III based HP laptop that stored the password on a chip that didn't require a battery to evade such a trick. The only fix was using the backdoor password that could be generated by using the serial number of the laptop (HP required proof of ownership, but I had dumpster dived this from their offices). The backdoor password was retrieved by wiring 50 USD to a fellow in the czech republic who had the keygen tool HP support would use.
