1,3,7,9 Power-on indicator/
power button (system
boards 1,2,4,3)
The power-on indicator lights
when the system power is on.
The power button controls the
DC power supply output to
the system.
When powering on the
system, the video monitor can take
from several seconds to over 2
minutes to display an image,
depending on the amount of
memory installed in the system.
On ACPI-compliant
operating systems, turning off the
system using the power button
causes the system to perform a
graceful shutdown before power to
the system is turned off.
To force an ungraceful
shutdown, press and hold the
power button for 5 seconds.
