Battery Gauge
You may check battery status from battery gauge. Click the power/battery icon to reveal the
battery gauge window. The following is the illustration of Battery Gauge in Windows OS.
Charging the Battery
Plug in the AC adapter or vehicle adapter to start the battery charging. If the battery is
already full, the sense circuitry will stop high current charge within several minutes.
The LED Indicator turns ON when the battery is charging and turns OFF when the battery
charge is completed.
To charge the Secondary Battery, simply install it into the computer and attach the AC
adapter. The internal charger will first charge the Primary battery and then Secondary one.
Optional Multi Battery Charger can charge Primary and Secondary batteries externally.
Note:
Battery characteristic varies depending on factors such as ambient
temperature, charging method, load current, aging, etc. For example, the
chemicals of the battery are more inactive at low temperature, thus decreases
the output power.
The battery gauge should only be used as a reference. Please do not expect it
to show the exact amount of the power remaining. There is no memory effect
on Lithium Ion battery cells. However, discharge the battery to nearly empty
every month will help calibrating the internal gauge.
