Note: Battery characteristic varies depending 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 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 calibrate the
internal gauge.
Charging the Battery
Plug in the AC adapter (or optional vehicle adapter) to start the battery charging.
If the battery is already full, the sense circuitry will stop high current charge
within several minutes.
There are two LED indicators next to the power indicator for the Primary and
Secondary battery respectively. 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”.
