Abstract: A vital resource for ubiquitous computing systems is energy. Today, energy has been elevated to the status of a first class operating system resource. A major challenge to the ubiquitous computing is how to manage the power consumption in a computer system so as to achieve goals in system performance, quality of service, complexity, cost, and energy conservation. Power-aware computing involves a wide range of systems, from mobile and embedded systems to high-performance servers. In this paper, we describe a Windows based power management tool called RPM that is used to provide power management for local and remote computer systems. The remote control feature of RPM is realised through the Distributed COM protocol. RPM manages the power consumption for an entire computer system, a CPU, or devices. Because it programs the hardware chipset power management registers directly, RPM is not dependent on CMOS setting for CPU power management. The system administrator can also use RPM as a tool for system and device diagnosis. Preliminary results indicate that RPM is a useful tool.
Keywords: computer power management; DCOM; system and device diagnosis; windows application.
