Power
Switching Between Battery and External Power
The notebook switches between external power and battery power according to the availability of external power. To conserve the charge in an inserted battery pack, the notebook runs on external power whenever external power is available. External power can be supplied from an electrical outlet through an
AC adapter or an optional DC cable.
If the notebook contains a charged battery pack and is running on external power, the notebook switches to battery power only if the AC adapter or DC cable is disconnected from the notebook.
The Power Meter icon in the system tray changes shape whenever the power source changes between battery power and external power.
Charging a Battery Pack
The battery pack charges whenever the notebook is connected to external power through an AC adapter or an optional DC cable.
The battery pack charges whether the notebook is turned off or turned on, but charges most quickly when the notebook is turned off. When the notebook is turned on, charging times are longer and vary with system activity.
The battery light displays charge status:
■On and amber: the battery pack is charging.
■On and green: the battery pack is fully charged.
■Flashing: the battery pack is malfunctioning and may need to be replaced.
