Disabling A Forgotten Password

The system's software security features include a system password and a setup password. The password jumper enables these password features or disables them and clears any password(s) currently in use.

CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.

1.Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.

2.Open the system.

3.Move the jumper on the system-board jumper from pins 4 and 6 to pins 2 and 4.

4.Close the system.

The existing passwords are not disabled (erased) until the system boots with the Jumper on pins 2 and 4. However, before you assign a new system and/or setup password, you must move the jumper back to pins 4 and 6.

NOTE: If you assign a new system and/or setup password with the jumper on pins 2 and 4, the system disables the new password(s) the next time it boots.

5.Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.

6.Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
