Laptop bios passwords are fairly good protection – unless they’ve been decrypted. Once that happens, the clever decryptor often releases their decryption method publicly. The acknowledged leader in bios decryption is Dogbert – a prickly personality coupled with mathmatical brilliance – my decryption efforts got a lot more successful once I’d found his blog.
Anyways, to recover your forgotten laptop bios password, you need to generate the machine ID code. This is a response shown on screen usually after 3-5 unsuccessful attempts at entering the bios passcode – brand dependent, Asus do it differently, so do Lenovo.
Once you’ve obtained the ID code or whatever your manufacturer calls it, use my BIOS Master Password Generator to recover your lost password. You’ll find the solution for (most, not all) Compaq, HP, Dell, Sony, Samsung, Fujitsu, Acer & Asus laptops with lost/forgotten BIOS passwords.
