reset password bios

Hello @НоутбукHP,



We are sorry as there is no master password or generator for EliteBooks or ProBooks.


HP Business Notebooks such as Probooks  or Elitebooks have more stringent security than consumer models infact 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.



  1. 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.


                                   When talking to the HP rep ask them to escalate your service request.




Please check my other post : http://h30434.www3.hp.com/t5/Notebook-Operating-System-and-Recovery/bios-admin-password/m-p/6060067/...


Hope this helps, for any further queries reply to the post and feel free to join us again !!
