Password Security and Resetting CMOS
Resetting the Password Jumper
To disable the power-on or setup password features, or to clear the
power-on or setup passwords, complete the following steps:
1. Turn off the computer and any external devices, then disconnect
the power cord from the power outlet.
Å
WARNING:
To reduce the risk of personal injury from electrical shock
and/or hot surfaces, be sure to disconnect the power cord from the wall
outlet, and allow the internal system components to cool before
touching.
Ä
CAUTION:
When the computer is plugged in, the power supply always
has voltage applied to the system board even when the unit is turned
off. Failure to disconnect the power cord can result in damage to the
system.
Ä
CAUTION:
Static electricity can damage the electronic components
of the computer or optional equipment. Before beginning these
procedures, ensure that you are discharged of static electricity by briefly
touching a grounded metal object. See the
Hardware Reference Guide
for more information.
2. Remove the access panel.
3. Locate the header labeled JCMOS1.
✎
For assistance locating the password jumper and other system board
components, see the Illustrated Parts Map (IPM) for your particular
system.
4. Move the jumper from pins 1 & 2 to pins 2 & 3.
5. Replace the access panel.
6. Connect the power cord to the power outlet. Turn on the system
and allow it to start.
✎
Placing the jumper on pins 2 & 3 clears the current passwords and
disables the password features.
