The Climate Savers Computing Power Management System Design Guide is a reference document on how to build energy‐efficient, power‐managed client platforms. Specifically, this guide presents guidelines and recommendations to achieve Standby (S3) state reliability, while reducing Standby, Resume and Sleep latencies resulting in positive user experiences.

PM implementation depends on successful interactions of the various computer platform elements. This guide will focus on aspects of the computer components, as well as platform design, operating systems and software to achieve consistent, reliable and efficient Standby operations across platforms. It can be used as a reference to build power‐efficient client systems, including the anticipated regulatory ENERGY STAR compliant proxy (Ecma TC38-TG4) devices.
