Abstract
A power management system for a PC card is disclosed. The power management system allows for a detachable battery pack to be used on a PC card. The PC card can select power from the personal computer or from the detachable battery pack. In one embodiment, power can also be selected from a DC wall adaptor, which can be connected to the PC card or battery pack. In another embodiment, the power controller on the PC card is always powered by the personal computer, so that the power management system can work even when a detachable battery pack is low in power or not connected to the PC card. The battery pack can be recharged from the DC wall adaptor or from the personal computer.
