DC IN The DC IN indicator normally glows green when
power is being correctly supplied from the AC
power adaptor. However, If the output voltage
from the adaptor is abnormal, or if the computer’s
power supply malfunctions, this indicator will go
out.
Power The Power indicator normally glows green when
the computer is turned on. However, if you turn
the computer off into Sleep Mode, this indicator
will flash amber - approximately one second on,
two seconds off - both while the system is
shutting down and while it remains turned off.
Battery The Battery indicator shows the condition of the
battery’s charge - green indicates the battery is
fully charged, amber indicates the battery is
charging, and flashing amber indicates a low
battery condition. Please refer to Chapter 6,
Power and Power-up Modes for more information
on this feature.

whenever the computer is accessing the built-in
hard disk drive or the other drives. It glows amber
when the ODD is loading a CD or DVD disc.
