Monitoring of power condition
As shown in the below table, the DC IN/Battery and Power indicators on
the system indicator panel alert you to the computer’s operating capability
and battery charge status.
DC IN/Battery indicator
Check the DC IN/Battery indicator to determine the status of the battery
pack and the power status with the AC adaptor connected. The following
indicator conditions should be noted:
Flashing amber The battery charge is low, the AC adaptor
must be connected in order to recharge the
battery.
Indicates a problem with the power supply.
You should initially try plugging the AC
adaptor into another power outlet - if it still
does not operate properly, you should
contact your reseller or dealer.
Amber Indicates the AC adaptor is connected and the
battery is charging.
White Indicates the AC adaptor is connected and the
battery is fully charged.
No light Under any other conditions, the indicator does
not light.
If the battery pack becomes too hot while it is being charged, the charge
will stop and the DC IN/Battery indicator will go out. When the battery
pack's temperature falls to a normal range, charging will resume - this
process will occur regardless of whether the computer's power is on or off.

that there is sufficient power available (AC
adaptor or battery) to maintain this condition. In
Sleep Mode, this indicator will turn on for one
second and off for two seconds.
