Hello everybody, I post this thread because I have a problem with a HP Probook 6550b. I can't have the BIOS password, and i can't remove it... I have try to remove the RTC barrery, i have try to use the Hiren's Boot CD with the BIOS crack... I have try to upgrade the BIOS with a HP Bios update utility but it need the password... All these solutions don't work ... Somebody can help me to remove this password ? Thank you.
