If you have enabled the Password on Boot field and you forget the supervisor password, you will not be able to boot up the computer. The same thing applies if you forget an HDD password. Your Aspire notebook has a hardware dip switch (SW1) for clearing lost system passwords. Go to page 18 for instructions on how to use this dip switch.
