8 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: administrator password and power-on password. When you establish only an administrator 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 administrator password gives you access to Computer Setup. When both passwords are set, the administrator password can also be used in place of the power-on password as an override to log in to the computer. This feature is useful for a network administrator. If you forget one or both passwords, you can clear all passwords by turning off the system, opening the cover, temporarily removing the PSWD jumper, and booting once. This action erases the administrator and poweron passwords. You must restore the jumper to create new passwords. IMPORTANT: Pushing the CMOS button with power removed resets the BIOS settings to factory defaults. It can be useful to back up the BIOS settings or save them as custom defaults before resetting them in case they are needed later. Back up can be performed in Computer Setup or using the BiosConfigUtility tool available from www.hp.com. See Computer Setup (F10) Utility on page 96 for information on backing up the BIOS settings. Resetting the password jumper IMPORTANT: Stringent security is a mode where there is no physical bypass of the password function. If enabled, removing the password jumper is ignored. To enable this mode, change the security setting Clear Password Jumper in Password Policies to Ignore. If you lose or forget the password when in stringent security mode, the system can only be reset by System Management Command. This is a way for HP Service and Support to provide a secure method to access the BIOS and command a password reset for a specifically identified unit under the direction of the owner. This scenario is not covered under warranty. To prevent needing a customer service event to restore access to the system, record your configured administrator and power-on passwords in a safe place away from your computer. To disable the power-on or administrator password features, or to clear the power-on or administrator passwords, complete the following steps: 116 Chapter 8 Password security and resetting CMOS
