Enhanced Security; Locking The Keyboard; Shutting Down Your Computer; Taking Care Of Your Computer - IBM IntelliStation Z Pro Type 6866 User Manual

Enhanced security

Your computer has an enhanced security feature that provides extra
protection for your administrator password and your startup sequence
settings. With enhanced security, your administrator password and startup
sequence are stored in a highly protected, nonvolatile, security EEPROM
module that is separate from CMOS memory and the EEPROM module that
stores system programs. When your administrator password and security
sequence are protected by enhanced security, they remain intact even if the
battery in your computer expires or is removed. For more information, see
"Using Enhanced Security" on page 40.

Locking the keyboard

You can disable the keyboard so that others are unable to use it. If a
power-on password is set, the keyboard is locked when you turn on the
computer. You must type the correct password before the keyboard will
unlock. You can enable the power-on password feature with the
Configuration/Setup Utility program. See Chapter 4, "Using the
Configuration/Setup Utility program" on page 37.
Some operating systems have a keyboard and mouse lock-up feature.
Check the documentation that comes with your operating system for more
information.

Shutting down your computer

When you are ready to turn off your computer, follow the shutdown
procedure for your operating system to prevent the loss of unsaved data or
damage to your software programs. See your operating system
documentation for instructions.
Important:
In some circumstances, the computer might not turn off immediately
when you press the power switch. In this case, hold the power switch
down for 5 to 10 seconds until the computer turns off.
