Abstract :
In this paper we show the measured power consumption of the different subsystems of the notebook with special emphasis on the power delivery subsystem. We prove by measurements that the energy efficiency of many of these subsystems can be significantly improved with a workload adaptive architecture without sacrificing performance at the peak load.
