Power plans missing - Restore power plans on Windows 7
Power saver plan on Windows helps you to give longer battery backup by reducing performance of certain hardware components like processor, graphics card, wireless network card etc and turning off devices which are not used. One sudden day my power saver option went missing on my sony vaio running Windows 7. Since the battery backup is drastically reduced when the power saver option is missing, I had to desperately find a fix and here it is :
The default power plans available in Windows are :- Power Saver
- Balanced
- High Performance
Due to corruption or some other reasons, Windows can loose track of your power plan. And the following screen appears saying "Your power plan information is not available".
Restore Power plans
Easy way : On the command line prompt run
powercfg -restoredefaultschemes
I believe the above command does the following steps as shown below. So in case the above command fails, follow the steps as shown below.
OR
If that doesnt work manually do the following.
The registry stores the details of the power plans and power states of the various devices under various conditions. It is stored in the following location under registry.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\User\PowerSchemes
.
Run regedit.exe
(You have to be an administrator)
On the left tree navigate to the above said location. Now the power plans called "PowerSchemes" is located in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\User\PowerSchemes
and
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\User\Default\PowerSchemes
Windows use the former to display the power plan options in control panel.
So if something is corrupted in the registry entry, you can restore it from the later registry entry.
This can be easily achieved by exporting HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\User\Default\PowerSchemes
to a .reg file, Search and replace all /Default/ with / and then import the same back into the registry.
This is "Example" of how the reg would look like after exported.

You might have to change the permissions of the keys, if you get a Permission Denied to write in "PowerSchemes". Right click the key and click permissions and then give full access for you or the administrator.
After doing this your power plans must be restored. :)
