A common myth is that HP laptops have a universal "backdoor" master password.
Some HP computers, including the ProBook series, have a backdoor password that can be used to access the BIOS settings and then reset the password.
: This method only works on older laptops with legacy BIOS systems and specific security chips. It is very unlikely to work on the HP ProBook 440 G6 (an 8th/9th-gen Intel system) due to its modern UEFI firmware and enhanced security. However, it's such a simple process that it's worth trying.
