7 Security

Protecting the computer

Standard security features provided by the Windows® operating system and the non-Windows Setup Utility (BIOS) can protect your personal settings and data from a variety of risks.

NOTE: Security solutions are designed to act as deterrents, but they may not deter software attacks or prevent the computer from being mishandled or stolen.

NOTE: Before you send your computer for service, back up and delete confidential files, and remove all password settings.

NOTE: Some features listed in this chapter may not be available on your computer.

Passwords can be set in Windows or in the non-Windows Setup Utility (BIOS) that is preinstalled on the computer.
