Abstract
A laptop computer storage system includes a power delivery system configured to negotiate charging Power Delivery Objects (PDOs) with each laptop computer connected to the computer storage system. The charging power delivery objects specify, for each laptop computer, the voltage and amount of current to be supplied to the particular laptop computer. Different charging power delivery objects are individually negotiated, and the computer storage system monitors the total amount of power being drawn by the connected set of laptop computers. As new laptop computers are connected to the computer storage system, power delivery objects that would cause the computer storage system to exceed a maximum power threshold are not presented to the newly connected laptop computer. As laptop computers become fully charged, the amount of current being drawn by the charged laptops will decrease, thus enabling additional charging power to be provided to other laptops within the computer storage system.
