This is one of the most effective methods for many older laptops, particularly Dells. When you enter an incorrect password multiple times (often three times), the system may lock and display a "System Disabled" code on the screen. This code, such as [XXXXX] , is a hash generated from the computer's Service Tag. Websites like bios-pw.org have databases of algorithms to reverse this hash and produce one or more potential master passwords. You simply enter the code you see on your screen, and the site generates a list of passwords to try. This has historically worked for a wide range of Dell, Acer, and other brands, especially those produced between roughly 2009 and 2015. Warning: This method is becoming less reliable on modern PCs as manufacturers upgrade their security algorithms.
