3.5.1 Password Security
The power-on password prevents unauthorized use of the computer by requiring entry of a
password to access applications or data each time the computer is turned on or restarted. The
setup password specifically prevents unauthorized access to Computer Setup, and can also be
used as an override to the power-on password. That is, when prompted for the power-on
password, entering the setup password instead will allow access to the computer.
A network-wide setup password can be established to enable the system administrator to log in to
all network systems to perform maintenance without having to know the power-on password,
even if one has been established.
3.5.2 Establishing a Setup Password Using Computer Setup
If the system is equipped with an embedded security device, refer to the HP ProtectTools
Security Manager Guide at
www.hp.com
. Establishing a setup password through Computer
Setup prevents reconfigration of the computer (use of the Computer Setup (F10) utility) until the
password is entered.

to bypass the title screen, if necessary.
✎
If you do not press

at the appropriate time, you must restart the computer and again press

when the monitor light turns green to access the utility.
