The new way is to make a bios password a factory only reset procedure. This was in response to stolen laptops. So to reset you contact the maker to find out how.
I have a Lenovo 80H1, the HDD died recently. After replacing the hard drive I needed to get into the BIOS and found it had a master password. Must have come from the factory that way. Lenovo has no idea what it might be. I don't either. How can I get past it or reset it?
