1. An apparatus, comprising:

  • a power management module having a power management controller;

    a managed power system to couple to the power management module, the managed power system comprising a communications sub-system and a computing sub-system, the power management controller to switch the communications sub-system and the computing sub-system to a lower power state to conserve energy, the communications sub-system having;

    a transceiver;

    a buffer to couple to the transceiver, the buffer to store packets of information for the transceiver during a communications idle duration period to create a computing idle duration period;

    a watermark generator to couple to the buffer, the watermark generator operative to generate a variable receive threshold value; and

    a buffer manager to couple to the buffer and the watermark generator, the buffer manager operative to transfer the stored packets of information from the buffer to the computing sub-system based on a variable receive threshold value.
