Parameters
;Power scheme GUIDs
The use of GUIDs avoids any problems with internationalisation when applying Power Saving to non-English versions of Windows. The three built-in power schemes have the aliases listed below, which can be used instead of the GUIDs:
*
SCHEME_MAX = Power saver (Max power saving)
*
SCHEME_BALANCED = Balanced (Typical)
*
SCHEME_MIN = High performance (Min power saving)
The other GUIDs have aliases as well.
Examples
Lists all power schemes
powercfg /l
List all Aliases
powercfg -aliases
Retrieve the currently active power scheme
powercfg -getactivescheme
Set the Monitor and disc timeouts for the current Power saver scheme
powercfg -Change -monitor-timeout-ac 20

Enable the mouse to wake from sleep
powercfg -deviceEnableWake "Microsoft USB IntelliMouse Explorer"
Set the 'Power saver' scheme
powercfg -SETACTIVE SCHEME_MAX
Create a Custom Power scheme and set it as active
Set _Custom_Power=B1234567-SS64-SS64-SS64-F00000111AAA
powercfg -DUPLICATESCHEME SCHEME_MAX %_Custom_Power%
powercfg -CHANGENAME %_Custom_Power% "SS64 Power Scheme "
powercfg -SETACTIVE %_Custom_Power%
Disable the sleep button (for the users current power scheme)
For /f "tokens=2 delims=:(" %%G in ('powercfg -getActiveScheme') do (

)
