Users should treat BIOS passwords on modern HP business laptops as secure against casual reset attempts but vulnerable to targeted physical attacks. hp probook 440 g6 bios password reset
The ability to bypass BIOS passwords via SPI reprogramming shows that physical access defeats firmware locking on the ProBook 440 G6.
