User Password A user password denies access to the system by an unauthorized user when the system is powered on. When a user password is active, the password prompt appears on the screen each time the system is powered on. The system starts after the proper password is entered. See "User Password" on page 20 for more information about how to change, remove and set password in Configuration/Setup Utility. In some cases, you might be required to service a system with an active and unknown user password. To clear a password from the system, follow these steps. 1. Turn off system unit. 2. Unplug power cable from the electrical outlet. IMPORTANT: Do not attempt these steps with the power cord plugged into the electrical outlet. The power supply maintains +5 Vdc of standby power when the power cord is plugged. System damage might result if the power cord is not unplugged during jumper setting. 3. Set JP20 to 2-3 position to clear BIOS setting as original manufacture setting. See "System Board Jumpers and Connectors" on page 113. IMPORTANT: To reinstall the password, the user must enter a password in the Configuration/Setup Utility. If Enhanced Security is enabled and the password is forgotten, the system board must be replaced. 10 IBM Desktop System HMM
