The guys over at Climate Savers Computing (CSC) have released a great little guide on how to design your power management system. CSC was started by Google and Intel in 2007,and is a nonprofit group of eco-conscious consumers, businesses and conservation organizations. The website is a great resource for anyone who is new to PC Power Management and I would recommend this guide as a great starting point. And for anyone else I would still recommend it! At just 30ish pages it's not too detailed, but contains enough pertinent information to get you up to speed quickly. Here's the blurb from their website..
'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.'
It explains the S3 power state, the user experience (very important!), how to test your machines etc. in a structured easy to follow way. I would thoroughly recommend that you download this guide - and of course our 1E whitepapers such as Why Power Schemes Are Not Enough. With hundreds of thousands of unmanaged desktops still out there, there's no excuse not to get started and save energy (and money) right away..
