Abstract-Recently, the demand of "Green Co mputing", wh ich represents an environmentally responsible way of reducing power consumption, and involves various environmental issues such as waste management and greenhouse gases is increasing explosively. We have laid g reat emphasis on the need to minimize power consumption and heat dissipation by computer systems, as well as the requirement for changing the current power scheme options in their operating systems (OS). In this paper, we have provided a comp rehensive technical review of the existing, though challenging, work on minimizing power consumption by computer systems, by utilizing various approaches, and emphasized on the software approach by making use of dynamic power management as it is used by most of the OSs in their power scheme configurations, seeking a better understanding of the power management schemes and current issues, and future directions in this field. Herein, we review the various approaches and techniques, including hard ware, software, the central processing unit (CPU) us age and algorith mic approaches for power economy. On the basis of analysis and observations, we found that this area still requires a lot o f work, and needs to be focused towards some new intelligent approaches so that human inactivity periods for co mputer systems could be reduced intelligently.
Gupta and Singh REF have presented the detailed survey on minimizing the power consumption by computer systems and discussed various key areas where energy-awareness policy could be implemented.
