Disabling a Forgotten Password

If you forget your system or setup password, you cannot operate your system or change settings in the System Setup program, respectively, until you remove the

computer cover, change the password jumper setting to disable the password(s), and erase the existing password(s).

To disable a forgotten password, follow these steps.

1. Remove the computer cover according to the instructions in "Removing the Computer Cover" in Chapter 5 in your Reference and Installation Guide.

2. Remove the jumper plug from the PSWD jumper to disable the password features.

Refer to Figure 1 for the location of the password jumper (labeled "PSWD") on the system board.

3. Replace the computer cover.

4. Reconnect your computer and peripherals to their electrical outlets, and then turn them on.

Booting your system with the PSWD jumper plug removed erases the existing password(s).

5. To reset the chassis intrusion detector, enter the System Setup program and reset Chassis Intrusion.

See "Chassis Intrusion" in Chapter 2 of your Reference and Installation Guide for instructions.

6. In the System Setup program, verify that the password is disabled. Continue with this procedure if you want to assign a new password.

Booting with the PSWD jumper installed reenables the password features. When you enter the System Setup program, both password settings appear as Not Enabled, meaning that

the password features are enabled but that no passwords have been assigned.
