@gurami, welcome back to the forum.

Here is the only solutions that HP provides:

Power On / BIOS Password

On HP Desktop PCs there are jumpers on the system board that are designed to remove BIOS passwords Search for the specifications documentation on your PC Find the document outlining the system or motherboard to locate CMOS and or Password Jumpers

HP Business Notebooks such as Probooks or Elitebooks have more stringent security than consumer models in fact they don't produce 'halt codes', the password cannot be derived from the Serial Number and the code is stored in non-volatile memory so removing the RTC cell will not reset the password in this case.

Please have a look at this link.

Please Contact HP Business Notebook support they should be able to send you a customized SMC.bin file which you can use at boot to reset the password.
