Note: Battery characteristic varies on factors such as ambient temperature, 
charging method, load current, aging, etc. 
For example, at low temperature the chemicals of the battery are more 
inactive, thus decreasing 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 calibrate the 
internal gauge. 
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 in 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 charge the Primary and Secondary 
batteries simultaneously. 
Optional Dual Battery Charger can charge Primary and Secondary batteries 
externally. 
Boot Up and POST 
The computer turns ON and loads the operating system (such as Windows) into 
the system memory. This start-up procedure is called “boot up”.
