When Windows Vista was initially released, some users claimed that it used even more battery on their laptop systems than Windows XP previously did. Obviously Microsoft added power management features into the operating system to save energy when needed, or let the computer run at full power, but some consumers still complained of high energy consumption altogether. As for Windows 7, the company is planning on doing even more to lessen the energy that the operating system uses, coupled with whatever green hardware and technology the manufacturer of the said system incorporates. In the new version of Windows, both the hibernation and standby modes are more efficient and reliable, which hopefully ensures that consumers will use the some variation of the two modes instead of leaving their computer on constantly. Power management is also being seen in the idle stages however, with Microsoft stating that even during keystrokes, Windows 7 will be able to save power since it is smarter in energy management overall. New tools included with the operating system can even help advanced users diagnose various hardware and device problems, along with application issues, that could cause power issues. All of the options that Redmond plans to implement in its next Windows delivery should not only grant laptop uses some extra time while using a battery, but will hopefully save on energy bills with desktops as well.
