Deleting or changing an existing system setup password

For this computer, the password clear feature is not performed with the service jumper. Instead, this function is accomplished through the power button.

The Master System Password is used to clear the admin and system password.

Note the code that appears on your locked computer's screen that is generated by hashing the computer's service tag. Dell customer support representative requires this code to generate the Master System password. Contact Dell customer support for receiving more assistance on resetting the system setup password.
