E Password Security and Resetting CMOS This computer supports security password features, which can be established through the Computer Setup Utilities menu. This computer supports two security password features that are established through the Computer Setup Utilities menu: setup password and power-on password. When you establish only a setup password, any user can access all the information on the computer except Computer Setup. When you establish only a power-on password, the power-on password is required to access Computer Setup and any other information on the computer. When you establish both passwords, only the setup password will give you access to Computer Setup. When both passwords are set, the setup password can also be used in place of the power-on password as an override to log in to the computer. This is a useful feature for a network administrator. If you forget the password for the computer, you can clear that password so you can gain access to the information on the computer by resetting the password jumper. CAUTION: Pushing the CMOS button will reset CMOS values to factory defaults. It is important to back up the computer CMOS settings before resetting them in case they are needed later. Back up is easily done through Computer Setup. See Computer Setup (F10) Utility on page 7 for information on backing up the CMOS settings. 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. Shut down the operating system properly, then turn off the computer and any external devices, and disconnect the power cord from the power outlet. 2. With the power cord disconnected, press the power button again to drain the system of any residual power. 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. 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. 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 Safety & Regulatory Information guide for more information. 3. Remove the access panel. 186 Appendix E Password Security and Resetting CMOS

Password Security and Resetting
CMOS
This computer supports security password features, which can be established through the Computer
Setup Utilities menu.
This computer supports two security password features that are established through the Computer
Setup Utilities menu: setup password and power-on password. When you establish only a setup
password, any user can access all the information on the computer except Computer Setup. When
you establish only a power-on password, the power-on password is required to access Computer
Setup and any other information on the computer. When you establish both passwords, only the
setup password will give you access to Computer Setup.
When both passwords are set, the setup password can also be used in place of the power-on
password as an override to log in to the computer. This is a useful feature for a network administrator.
If you forget the password for the computer, you can clear that password so you can gain access to
the information on the computer by resetting the password jumper.
CAUTION:
Pushing the CMOS button will reset CMOS values to factory defaults. It is important to
back up the computer CMOS settings before resetting them in case they are needed later. Back up is
easily done through Computer Setup. See
Computer Setup (F10) Utility
on page
7
for information on
backing up the CMOS settings.
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.
Shut down the operating system properly, then turn off the computer and any external devices,
and disconnect the power cord from the power outlet.
2.
With the power cord disconnected, press the power button again to drain the system of any
residual power.
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.
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.
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
Safety & Regulatory Information
guide for more
information.
3.
Remove the access panel.
