Onboard Power LED

There is an Onboard Power LED (LE1)
located on the motherboard. When LE1 is
off, the system is off. When the green light
is on, the system is on. When the yellow
light is on, the system is off, but the AC
power cable is still connected. Make sure
to disconnect the power cable before re-
moving or installing components. See the
layout below for the LED location.
POST LEDs
There are two POST (Power-On Self Test)
LEDs (LE3, LE4) located on the mother-
board. The green LED is LE3; while the
yellow LED is LE4. These LEDs indicate
POST activities during system bootup.
Refer to the table on the right for details.
Also see the layout below for the LED
