1. If a laptop produces a hash code after 3 wrong entries then there are generators that will produce the master password for that hash code.

2. If a laptop does not produce a hash code then a SMC.bin file will be needed to remove the password.

3. Sometimes removing the RTC/BIOS battery will work.

4. If  1, 2 and 3 do not work then the only thing left is to replace the BIOS chip:
