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.
Prerequisites
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.
Steps
1.
Turn off the system, including any attached peripherals, and disconnect the system from the
electrical outlet.
2.
Remove the system cover.
3.
Move the jumper on the system board jumper from pins 2 and 3 to pins 1 and 2.
4.
Install the system cover.
The existing passwords are not disabled (erased) until the system boots with the jumper on pins 1 and
2. However, before you assign a new system and/or setup password, you must move the jumper
back to pins 2 and 3.
NOTE: If you assign a new system and/or setup password with the jumper on pins 1 and 2, the
system disables the new password(s) the next time it boots.
