Cmos or bios administrator password forgotten

Hello 3bdom7sn,

 

 

 Welcome to HP Support Forum and we are glad to assist you.

 

This is to inform you that all 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 have a look at this link.

  1. Replace the BIOS chip

  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.

 

 

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

HI.

 

Contact the technical support, if you do not remember the password is a problem, in these cases it is best to call and follow the steps you are told as the steps to follow are complicated and always have to do a specialist EEPROM or Reprogram it.
