Hi admin.

I had a problem. My nephew set an administrator password to enter the BIOS and can not remember it.
I do probyval restore BIOS from a USB device, but nothing has changed. I took off the cover and disconnect the battery with the BIOS on the day, and also did not get the result.
The forum is a response to a password reset the BIOS on the HP Elitebook and Probook, but unfortunately my model is not listed there, and I was not able to do what I need.
Tell me how can this be done?
