Welcome to the HP Support Community @atanapet


For that model you will need to contact HP in your region and they should be able to send you a customized SMC.bin file which you can use at boot to reset the password.


Phone >>


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


Just to note:


Do not try removing the RTC battery.  It will not remove the password, but it will reset the clock - as SMC files are time coded, a large disparity between the system clock and the time encoded in the SMC  will cause it to fail.

Thank you for the reply, I've contacted our HP service provider, but they told me that they can not provide me SMC.bin file, so I can not reset the password.

Anyway thank you for the explanation.
