Thermal stress relief with power management [desktop computer systems]

This paper considers the impact of the EPA's Energy Star energy-saving guidelines on the reliability and life of desktop computer systems. Energy Star compliance results in an increase in daily power up/down cycles. The consequent thermal shock and mechanical stresses on the system can adversely affect its life. Predictive models estimate that the cumulative effect depends on the frequency and magnitude of these power transitions, and can halve the life of a computer system. We review the Energy Star requirements, their implications for system life, and suggest a practical approach to maintain product reliability.
