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, there are two methods
for clearing that password so you can gain access to the information
on the computer:
■ Resetting the password jumper
■ Using the Clear CMOS button
Ä
CAUTION: Pushing the CMOS button will reset CMOS values to factory
defaults and will erase any customized information including passwords,
asset numbers, and special settings. 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 the Computer
Setup (F10) Utility Guide on the Documentation CD for information on
backing up the CMOS settings.
