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.
