power Scheme GUID: a1841308-3541-4fab-bc81-f71556f20b4a  (Power saver)
-QUERY
-Q
Displays the contents of the specified power scheme.
Usage: POWERCFG -QUERY scheme_Guidsub_guid

scheme_Guid (optional) the GUID of the power scheme to display, can be obtained by using powercfg -l.
sub_guid (optional) the GUID of the subgroup to display. Requires a SCHEME_GUID to be provided

If neither SCHEME_GUID or SUB_GUID are provided, the settings of the current user's active power scheme are displayed.
If SUB_GUID is not specified, all settings in the specified power scheme are displayed.

Example: set the monitor idle timeout value to 5 minutes when on AC power.
POWERCFG -Change -monitor-timeout-ac 5
-CHANGENAME Modifies the name of a power scheme and optionally it's description.

Usage: POWERCFG -CHANGENAME GUID <name> <scheme description>

If the description is omitted only the name will be changed.

-DUPLICATESCHEME Duplicates the specified power scheme. The resulting GUID which represents the new scheme will be displayed.

Usage: POWERCFG -DUPLICATESCHEME guid <destination GUID> guid a scheme GUID obtained by using the powercfg -l If is omitted, a new GUID will be created for the duplicated scheme.

-DELETE
-D
Deletes the power scheme with the specified GUID. Usage: POWERCFG -DELETE <GUID> guid obtained by using the LIST parameter.
-DELETESETTING Deletes a power setting. Usage: POWERCFG -DELETESETTING <SUB_GUID> <SETTING_GUID> SUB_GUID the subgroup GUID. setting_GUID the power setting guid.
-SETACTIVE
-S
Makes the specified power scheme active on the system.

Usage: POWERCFG -SETACTIVE schemeGUID schemeGUID the scheme guid.

-GETACTIVESCHEME Retrieve the currently active power scheme.

-SETACVALUEINDEX Sets a value associated with a specified power setting while the system is powered by AC power.

Usage: POWERCFG -SETACVALUEINDEX schemeGUID SUB_GUI setting_GUID SettinhIndex

schemeGUID a power scheme GUID and may be obtained by using PowerCfg /L.
SUB_GUID a subgroup of power setting GUID and ma be obtained by using "PowerCfg /Q."
setting_GUID an individual power setting GUID and ma be obtained by using "PowerCfg /Q".
SettinhIndex which of the list of of possible values this power setting will be set to.

Example: set the power setting's AC value to the 5th entry in the list of possible values for this power setting.
POWERCFG -SetAcValueIndexguidguidguid 5

-SETDCVALUEINDEX Sets a value associated with a specified power setting while the system is powered by DC power. Usage: POWERCFG -SETDCVALUEINDEX schemeGUID SUB_GUID setting_GUID SettinhIndex schemeGUID a power scheme GUID and may be obtained by using PowerCfg /L.
SUB_GUID a subgroup of power setting GUID and ma be obtained by using "PowerCfg /Q."
