General Information 11
Power-On Password
A power-on password denies access to the system by
an unauthorized user when the system is powered
on. When a power-on 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 Power-On
password on page 21 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 power-on
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 JP14 to 2-3 position to clear BIOS setting as
original manufacture setting. See System Board
Jumpers and Connectors on page 109.
4. Set JP7 back to the 1-2 position to enable
password check process. See System Board
Jumpers and Connectors on page 109.
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.
