With the upcoming release of Windows 7 we wanted to provide you with more information on the new power management features in the product and ways that we’re driving energy efficiency across the PC ecosystem.
Microsoft recognizes that software can play a critical role in helping companies reduce operational costs and their carbon footprint. We also understand the importance of energy efficiency for our customers and for the broader environment, and we are designing our products to minimize environmental impacts. We designed our latest operating system, Windows 7, with a strong focus on reducing the overall power consumption by investing in key areas of the platform including performance optimizations, idle resource utilization, device power management, and key end-user scenarios.
Energy efficiency — both when the PC is in use and when it is turned off — has been a guiding principle in the development of Windows 7. We’ve built on previous Windows versions and the core design of Windows 7 incorporates energy efficiency features that enable IT Pros to manage energy consumption in their business. IT professionals can easily deploy a power management policy within their enterprise, such as turning off the display and enabling Sleep after a period of inactivity Windows 7 also includes new diagnostics, Idle Power Management, Active Power Management and Wake on LAN for Remote Management to help IT professionals identify and resolve PC power management problems in their enterprise. Windows 7 can also help extend battery life and reduce energy use in key user scenarios.
Dramatic improvements in energy efficiency also requires a close collaboration with others in the IT industry and we’ve worked actively with our partners in the Windows ecosystem, including PC manufacturers, other device manufacturers, and software vendors, to help ensure that their products are optimized for Windows 7 and can take advantage of the energy efficiency improvements in Windows 7.
The energy efficient features of Windows 7 include:
· Idle Power Management: Windows 7 helps to save energy by ensuring that the PC is not performing unnecessary activities when it is idle. For example, if a user walks away from a computer, Windows takes advantage of idle time to scale the hardware down to the lowest available power consumption level. Another feature that helps reduce idle power consumption is Adaptive Brightness, which allows the display to dim after a short period of inactivity and, in turn, reduces the amount of power used.
· Active Power Management: Windows 7 also includes new features to help improve energy efficiency when the PC is in use, as well as extend mobile PC battery life. For instance, with new networking power improvements, Windows automatically places the network adapter into a low-power state when a user disconnects his or her network cable.
· New Diagnostics: new tools will help improve IT administrators’ ability to diagnose and troubleshoot power problems across their enterprises. For example, the diagnostic tools in Windows 7 can help IT professionals determine which applications or devices are negatively impacting energy efficiency and how much normal degradation has occurred to the battery of a mobile PC. These tools will enable more efficient power management of PCs across organizations.
· Improved Remote Management: IT administrators deploy policies that place PCs automatically in “sleep mode” when they are not in use. Windows 7 also improves the IT administrators’ ability to manage such PCs remotely by enabling as default a function that allows the PCs to be “woken up” through a simple network message.
I encourage you to read the Windows 7 Power Management whitepaper for more information.
UPDATED ON JUNE 16: fixed broken link for white paper. The correct link should be http://download.microsoft.com/download/8/5/4/854F66B6-8C09-4F8A-986E-38E9EBAC1677/Windows7_Power_Management_Whitepaper.pdf
Microsoft’s Environmental Sustainability Blog has posted an excellent blog post today highlighting Windows
I'd like to encourage you to offer a power auditing tool to show me what third party software and hardware is doing to both my performance and power management. If an anti-virus tool makes me install, reboot, update and reboot, I can see it's not well written - but how am I going to know if it's stopping my PC going into idle, or if my USB device has the wrong power settings? A Power and Perf power toy would be a huge help to people...
have a look at the powercfg utility. when you use the /energy switch you can figure out which devices/apps are consuming energy.
What does Microsoft have to say to this comparison->: http://anandtech.com/mac/showdoc.aspx?i=3582 ?
Don't forget enterprise management software for Windows!
