Internal Battery
The internal battery is not user-replaceable and is not visible to the operating system. It never functions
as the power source as long as the hot swappable battery pack is installed. It enables the hot-swapping
function, since it provides power only when the battery pack is removed. The internal battery should not
be used to power the tablet during regular operation.
By default, the internal battery is charged by external AC power (if connected) or the main battery pack
if it is not fully charged. To preserve battery life, it is possible to set the internal battery to charge only
when connected to an AC Power Source.
