This is a known issue. Windows 7 does not apply customized power plan policy created by Group Policy Management Editor.Repro steps: (w and w/o SP1)==========1. Open group policy management editor=>computer configuration=>preferences=>control panel settings=>power options2. Create new power plan, in ACTION column, choose “Create” option3. In next column choose either of the build in plan, choose “High performance” as an example.4. Check the “set as the active power plan”5. Customize power plan settings6. Click ok the finish policy setting.7. In windows 7, restart computer to apply computer policy.8. Open power option, you will find the “High performance” box is not checked. But customized settings such as idle time are applied.Note: this problem also exists in user configuration.Solution:
=========In the new power plan properties, there is four options in ACTION column “create” ”update” ”replace” ”delete”, choose the “update” option instead of “create”, then problem will not occur.Do not choose "Create" or "Replace”, instead, choose "Update" then it works fine.
Read the following article. At the end the behavior of Replace/Update/Delete/Active is explained:

nothing affects it...it turns display off every two minutes....how lame
This does not work either. Creating a new power plan using the Update option does not default it to active.
agree, doesn't work. This is yet another example of these preferences just not working. What a shame.
