The HP ProBook/EliteBook BIOS Password Reset Utility is a free, downloadable tool that enables users to reset the BIOS password on HP ProBook and EliteBook laptops. The utility works by exploiting a vulnerability in the BIOS firmware, allowing it to bypass the password prompt and reset the password to a default value. This utility supports a wide range of HP ProBook and EliteBook models, including those from the 2010s and 2020s.
