1. A mobile computing device, comprising:

  • a central processing unit (CPU);

    memory that communicates with said CPU;

    an interface that communicates with said memory and said CPU;

    a display that communicates with said interface;

    a first distributed load center having first and second load terminals and including at least a first distributed load, wherein said first distributed load includes at least one load that is selected from a group consisting of said CPU, said memory, a graphics processing unit (GPU) that communicates with said interface, a hard disk drive (HDD) that communicates with said interface, and a DVD drive that communicates with said interface;

    a second distributed load center having first and second load terminals and including at least a second distributed load, wherein said second distributed load includes at least one load that is selected from a group consisting of said CPU, said memory, a graphics processing unit (GPU) that communicates with said interface, a hard disk drive (HDD) that communicates with said interface, and a DVD drive that communicates with said interface;

    a first distributed power system that includes a first battery that is directly connected and primarily supplies power to said first and second load terminals of said first distributed load center; and

    a second distributed power system that includes a second battery that is directly connected and primarily supplies power to said first and second load terminals of said second distributed load center, wherein said first load terminals of said first and second distributed load communicate and said second load terminals of said first and second distributed load center communicate, and wherein said first distributed power system supplies power to said second distributed load center and wherein said second distributed power system supplies power to said first distributed load center.
