You use your computer's setup program to activate and install a boot-up password that is required before the machine will continue to load its programs. Give a copy of the password to your supervisor for safe keeping and emergencies. If you forget your password, the machine's battery must be removed or a special switch deactivated to reset the password activation. This may take up to 20 to 30 minutes to accomplish. For help in setting your boot-up password please check your system's documentation.
Different systems have different setup instructions and activation programs.
If you are completely stumped, contact the Help Center for help in activating the boot-up password.
