For more information about the Liquid Crystal Display, read the section “LCD Information” in Chapter 7 of this document.

System Power Switch

The power switch is used to turn the system unit on and off. When you turn your computer off, the operating system executes an automatic shutdown -qcommand. This prevents any damage to programs and data on your system disk. Turning the power switch back on again automatically boots up the HP-UX 10.20 or later operating system if your system has been configured to auto boot. For information on setting auto boot, read the section “Setting the Auto Boot and Auto Search Flags” in Chapter 6 of this document.
