Disabling a Forgotten Password
The system's software security features include a system password and a setup password, which are discussed in detail in "Using the System Setup
Program" in the User's Guide. A password jumper on the system board enables these password features or disables them and clears any password(s)
currently in use.
To disable a forgotten system password or setup password, perform the following steps.
1. Open the system covers. See "Opening the System Covers" in "Troubleshooting Your System."
2. See FigureA-2 for the location of the password jumper (labeled "PASSWD") on the system board.
3. Remove the jumper plug from the PASSWD jumper.
4. Close the system covers. See "Closing the System Covers" in "Troubleshooting Your System."
5. Reconnect the system to an electrical outlet and turn it on.
The existing passwords are not disabled (erased) until the system boots with the PASSWD jumper plug removed. However, before you assign a new
system and/or setup password, you must reinstall the jumper plug.
6. Repeat step 1.
7. Install the jumper plug on the PASSWD jumper.
8. Close the system covers, and then reconnect the system and peripherals to their electrical outlets and turn them on.
9. Assign a new system and/or setup password.
To assign a new passwords using the System Setup program, see "Assigning a System Password" in the User's Guide.

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See
your System Information Guide for complete information about safety precautions, working inside the computer, and protecting against
electrostatic discharge.
NOTE: If you assign a new system and/or setup password with the jumper plug still removed, the system disables the new password(s) the next
time it boots.
