1. An apparatus comprising:
- an enclosure including a processor and memory device;
an internal charger to receive DC power from an external supply and provide charging current to charge a battery;
a battery connector to receive current from the internal charger and to provide current to the processor and memory devices;
a fast charge connector to receive a fast charging current from a fast charger module at multiple selectable voltage levels and selectively couple the fast charging current to the internal charger.

Abstract
A system and method include detecting whether a fast charger module is coupled to a system having a processor and a memory device. If the fast charger module is coupled to the system, a fast charging current is provided from the fast charger module at multiple selectable voltage levels via an internal charger. If the fast charger module is not detected as coupled to the system, a charging current is provided from an AC adapter via the internal charger.
