For more information about the Liquid Crystal Display, read the section

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 -q command. 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 operating system and the
Workstation Additional Core Enhancements for HP-UX 10.20 (June
1999) 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.
