10 IBM Desktop System HMM
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.
