Hardware and Software Guide 6–1 6 Security Security Features ✎Security solutions are designed to act as deterrents, but they may not be able to deter software attacks or prevent the computer from being mishandled or stolen. Standard security features provided by the Windows operating system and the non-Windows Setup Utility (accessed by pressing f10 at startup) can protect your personal settings and information from a variety of risks. Follow the procedures described later in this guide for using ■Passwords ■Antivirus software ■Critical security updates ■Firewall software ■Optional security cable

Security Hardware and Software Guide 6–3 QuickLock QuickLock protects your computer by displaying the Windows operating system Log On window. While the Log On window is displayed, the computer cannot be accessed until a Windows user password or Windows administrator password is entered. Before you can use the QuickLock feature, you must set a Windows user password or Windows administrator password. Then ■To initiate QuickLock, press fn+f6. ■To exit QuickLock, enter your Windows user password or Windows administrator password. Ty p e s o f Pa s s wo r d s A password is a group of characters that you set to secure your computer information. Several types of passwords can be set, depending on how you want to control access to your information. Passwords can be set in Windows or in the non-Windows Setup Utility preinstalled on the computer. Ä CAUTION: To prevent being locked out of your computer, record each password you set. Because most passwords are not displayed as they are set, changed, or deleted, it is essential to write down each password immediately, and store it in a secure place. The following tables list commonly used Setup Utility and Windows passwords and describe their functions.

ÄIf you forget the administrator password, you cannot access the Setup Utility.

ÄIf you forget the power-on password, you cannot turn on the computer, restart, or restore from hibernation.
Security Hardware and Software Guide 6–5 Coordinating Passwords A Setup administrator password and a Windows administrator password have different functions. A Windows administrator password cannot be used to access Setup, and a Setup administrator password cannot provide administrator-level access to your computer contents. Setup Utility and Windows passwords function independently. You must use a Setup Utility password at a Setup Utility password prompt and a Windows password at a Windows password prompt. For example: ■If a Setup Utility power-on password is set, the power-on password (not a Windows password) must be entered when the computer is turned on, restarted, or restored from hibernation. ■If a Windows standby password is set, the Windows standby password (not a Setup Utility power-on password) must be entered when the computer is resumed from standby or restored from hibernation.
6–6 Hardware and Software Guide Security Guidelines for Setting Passwords You can use the same password for a Setup Utility feature that you use for a Windows security feature. You can also use the same password for more than one Setup Utility feature. A password set in the Setup Utility: ■Can be any combination of up to 8 letters and numbers and is not case sensitive. ■Must be set and entered with the same keys. For example, a password set with keyboard number keys will not be recognized if it is thereafter entered with embedded numeric keypad number keys. ✎Select models include a separate numeric keypad, which functions exactly like teh keyboard number keys. ■A password set in the Setup Utility must be entered at a Setup Utility prompt. A password set in Windows must be entered at a Windows prompt. Administrator Password The administrator password protects the configuration settings and system identification information in the Setup Utility. After this password is set, it must be entered to access the Setup Utility. The administrator password ■Is not interchangeable with an administrator password set in Windows, although both passwords can be identical. ■Is not displayed as it is set, entered, changed, or deleted. Be sure you record the password and store it in a secure place.

Antivirus software can detect most viruses, destroy them, and in most cases, repair damage they have caused. To protect your computer against viruses, it is recommended that you use antivirus software. To provide protection against newly discovered viruses, the antivirus software must be updated. Antivirus software is preinstalled on the computer: ■The software includes free updates for a limited period of time. It is strongly recommended that you protect your computer against new viruses by purchasing extended update service. ■Instructions for using and updating antivirus software and for purchasing extended update service are provided with the application. ■To view and access the software preinstalled on your computer, select Start > All Programs.
