How to Clear a Password?
If you remember your supervisor password, it is very easy to clear it: switch your computer on, enter the menu of BIOS settings and select the command “Supervisor password” or “User password”. In both cases you will be first prompted to enter the current password and then enter the new one after pressing Enter button. If you leave this field blank and press Enter button, the password will be deleted and the system of password protection will be unlocked. If this action is performed for the supervisor password, the user password will be deleted automatically. After deletion or changing of the passwords, you must save all changes in BIOS and reboot your computer.
