Power Indicator
The power indicator on the front of the computer has a light-emitting diode (LED) that illuminates in two different colors and blinks or remains solid
to indicate several different states. See "
Diagnostic LEDs
" for a description of each of these states.
Power Button
The power button controls the system's AC input power.
The Microsoft Windows 98 and Windows 98 Second Edition (SE) operating systems let you configure the function of the power button through the
Advanced Configuration and Power Interface (ACPI) feature (see Table 1).
NOTICE: To turn off your computer system, perform an orderly system shutdown using the operating system menu when possible.

operating systems that have the ACPI feature disabled.
