Reset BIOS Administrator on my Hp Probook 4540s

HP Probook 4540s
Microsoft Windows 7 (64-bit)

Hi there, Is there any chance to reset the BIOS admin password? I wanted to check the wifi configuration in BIOS if enabled because I can't turn on the wifi with the button on laptop. I forgot the password. I try to removed the CMOS battery but it's not working. Is there any chance to reset or remove the password? or I should buy a new BIOS chip? :(

 

here's the Screenshot:

Reset BIOS Administrator on my Hp Probook 4540s

@Junix17,

 

 

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.

 

 Try logging in to BIOS as USER, Restore Defaults- Save Changes and exit, And see if that works !!

 

 

 

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