Abstract

The disclosed embodiments relate to power systems and methods. One such power system includes an adapter that produces a power output. A converter stage receives the power output and in turn provides a regulated output. The regulated output is delivered to a battery and to a DC-DC component.

Claims

1-12. -12. (canceled)

6. An electronic device comprising:

a processor;

a memory capable of storing data to be accessed by the processor; and

a power system comprising;

a power adapter capable of producing a power output;

a converter stage coupled to receive the power output and generate a regulated output;

a DC-DC component coupled to receive the regulated output; and

a battery removably coupled to receive the regulated output.

7. The power system set forth in claim 6, comprising a video adapter operatively coupled to the processor to create an image signal.

8. The power system set forth in claim 7, comprising a monitor to receive the image signal and display a corresponding image to a user.

9. The power system set forth in claim 8, comprising a user input device to receive input from a user.

10. The power system set forth in claim 6, comprising a feedback circuit to provide feedback from the battery to the converter stage to manage the charging of the battery.

11. The power system set forth in claim 10, wherein the battery comprises:

a first switch connected to a terminal of the battery; and

a second switch connected between the first switch and the feedback circuit, wherein the first and second switches enable the charging of the battery.

12. The power system set forth in claim 6, wherein the DC-DC component adjusts the regulated output into different voltages to be applied to other circuits connected to the power system.

13. The power system set forth in claim 6, comprising a battery circuit to monitor current and voltage levels at the battery to regulate charging of the battery.
