What is the process to delete my system's setup or power-on password?
To remove a Setup or Power-On password, turn on your computer and immediately press the Esc key then F10 for Computer Setup. For deleting, type current password followed by a '/' at the key icon prompt (example: currentpassword/), and press Enter to complete deletion (Page 3).
