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.

If you 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.
