My Dell projector is out of warranty and I forgot the password to unlock it. How can I do a reset or get a code to bypass it?
To reset the password, you have to call Dell support. They will generate a master reset password based on your serial number. The purchase bill is also necessary for this procedure. To read more about it, consult the Dell forums where this matter is addressed.
