The DC IN indicator normally glows white 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
flash amber.
The Power indicator normally glows white 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.
The Battery indicator shows the condition of the
battery's charge - white 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
