Low power consumption is an important factor in designing a PC system. Dynamic power management (DPM) can be an effective approach to the reduction of power consumption without significantly degrading performance. A system shuts down devices when they are not needed and wakes them up when necessary. When a system shuts down or wakes up, it requires extra power consumption. In this paper, we measure the power consumption for the state transition penalty, sleep and idle state; which can be used to decide the effective sleep time interval for dynamic power management of a PC. We also focus on the penalty of the power consumption in state transition for a typical PC and build a simple model for the effective sleep time interval with respect to the CPU clock rates and the physical memory size used.
