Power indicators

As shown in the below table, the Battery, DC IN and Power indicators on the system indicator alert you to the computer’s operating capability and battery charge status.

Battery indicator

Check the Battery indicator to determine the status of the battery pack - 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.
Amber	Indicates the AC adaptor is connected and the
	battery is charging.
Green	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 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.
