What is claimed is: 1. A computer servicing cart comprising: an outer cabinet; a first battery servicing compartment disposed in the outer cabinet for selectively charging one or more batteries; a first computer storage compartment disposed in the outer cabinet and including a first electrical outlet for selectively charging one or more computers; a first internal power supply for providing power to the at least the first battery servicing compartment; and a power shedding circuit including a current sensing device operable to be in electrical communication with an external electrical outlet, the current sending device including means for providing a signal indicative of a current drawn from the external electrical outlet, a first relay in electrical communication with the first internal power supply, the first relay including means for selectively connecting the first internal power supply to the first computer storage compartment, and a logic circuit in electrical communication with the current sensing device and the first relay, the logic circuit including means for operating the first relay based on a comparison of the current being drawn from the external electrical outlet as indicated by the signal to a predefined limit. 2. The computer servicing cart of claim 1 where the first internal power supply is selectively connectable to the external electrical outlet. 3. The computer servicing cart of claim 1 wherein the first computer storage compartment further includes: at least one shelf; at least one electrical outlet adjacent to each shelf; and at least one compartment adapted to conceal at least one AC/DC adapter for use with a computer. 4. The computer servicing cart of 3 wherein: each shelf adjusts vertically; each shelf is tilted downward toward a back end at a predetermined angle; each shelf has a recessed portion near a front end adapted to facilitate insertion and removal of computers; and each shelf has a retainer adapted to guide an adapter cord to the computer. 5. The computer servicing cart of claim 1 wherein the outer cabinet includes a plurality of wheels. 6. The computer servicing cart of claim 1 further comprising a cooling system. 7. The computer servicing cart of claim 1 wherein the first battery servicing compartment further includes a storage system adapted for storing the one or more batteries. 8. The computer servicing cart of claim 7 wherein the first battery servicing compartment is adaptable to store and charge different battery types. 9. The computer servicing cart of claim 1 further comprising: a second internal power supply; a second computer storage compartment; wherein the power shredding circuit further includes a second relay in electrical communication with the first internal power supply, the second relay including means for selectively connecting the first internal power supply to the second computer storage compartment; and wherein the logic circuit includes: means for closing the first and second relays, and activating the second power supply in a predetermined order when the first power supply is activated; means for opening the relays and deactivating the second power supply in a predetermined order when the current sensing device indicates the current being drawing from the external electrical outlet in excess of the predefined limit; means for recording a relay or power supply and a current drawn by the relay or power supply that cause the current drawn that is over the predefined limit; means for monitoring the current drawn from the external electrical outlet such that a deactivated power supply or an opened relay can be activated or closed respectively when the current drawn from the external outlet has fallen enough to allow reactivation or closing without causing current to be drawn that is in excess of the predefined limit; and means for deactivating the second power supply and opening the first and second relays when the first power supply is deactivated. 10. A computer servicing cart comprising: a first battery servicing module for selectively charging one or more batteries; a first computer storage module including at least one electrical outlet for selectively charging one or more computers; a first internal power supply for providing power to the at least the first battery servicing module; and a power shedding circuit including a current sensing device operable to be in electrical communication with an external electrical outlet, the current sending device including means for providing a signal indicative of a current drawn from the external electrical outlet, a first relay in electrical communication with the first internal power supply, the first relay including means for selectively connecting the first internal power supply to the first computer storage module, and a logic circuit in electrical communication with the current sensing device and the first relay, the logic circuit including means for operating the first relay based on a comparison of the current being drawn from the external electrical outlet as indicated by the signal to a predefined limit. 11. The computer servicing can of claim 10 where the first internal power supply is selectively connectable to the external electrical outlet. 12. The computer servicing cart of claim 10 wherein first computer storage module further includes: at least one shelf; at least one electrical outlet adjacent to each shelf; and at least one compartment adapted to conceal at least one AC/DC adapter for use with a computer. 13. The computer servicing cart of claim 12 wherein: at least one shelf adjusts vertically; at least one shelf is tilted downward toward a back end at a predetermined angle; at least one shelf has a recessed portion near a front end adapted to facilitate insertion and removal of computers. 14. The computer servicing cart of claim 10 wherein the first battery servicing module further includes a storage system adapted to store the one or more batteries. 15. The computer servicing cart of claim 14 wherein the first battery servicing module is adaptable to store and charge different battery types. 16. The computer servicing cart of claim 10 further comprising a wheeled transport module, the transport module including: a plurality of wheels attached to a frame; wherein the frame is adapted to detachably receive at least the first computer storage module and the first battery serving module. 17. The computer servicing cart of claim 10 further comprising a ventilation system. 18. The computer servicing cart of claim 1 further comprising: a second computer storage module; a second power supply disposed in the first battery servicing module; and wherein the power shredding circuit further includes: a second relay electrical communication with the first internal power supply, the second relay including means for selectively connecting the first internal power supply to the second computer storage module; and wherein the logic circuit includes: means for closing the first and second relays, and activating the second power supply in a predetermined order when the first power supply is activated; means for opening the relays and deactivating the second power supply in a predetermined order when the current sensing device indicates the current being drawing from the external electrical outlet in excess of the predefined limit; means for recording a relay or power supply and a current drawn by the relay or power supply that caused the current drawn that is over the predefined limit; means for monitoring the current drawn from the external outlet such that a deactivated power supply or an opened relay can be activated or closed respectively when the current drawn from the external outlet has fallen enough to allow reactivation or closing without causing current to be drawn that is in excess of the predefined limit; and means for deactivating the second power supply and opening the first and second relays when the first power supply is deactivated.
