Hi,
Unfortunately, business machines such as Probooks or Elitebooks have more stringent security than consumer models - they don't produce 'halt codes', the password cannot be derived from the Serial No. and the code is stored in non-volatile memory so removing the RTC cell will not reset the password in this case.
As there are no 3rd party utilities that will work for this particular Model, you'll need to Contact HP Business support - they should be able to send you a customised SMC.bin file which you can use at boot to reset the password.
