Abstract :
Summary form only given. Optimal power management policies for a laptop hard disk are obtained with a system model that can handle non-exponential interarrival times in the idle and the sleep states. the measurement results on a Sony Vaio laptop show that our policy has 1.7 times less power consumption as compared to the default Windows timeout policy with still high performance.
