POWERCFG <command line options>
Description:
This command line tool enables users to control the power settings
on a system.
Parameter List:
-LIST, -L Lists all power schemes in the current user's environment.
Usage: POWERCFG -LIST
-QUERY, -Q Displays the contents of the specified power scheme.
Usage: POWERCFG -QUERY <SCHEME_GUID> <SUB_GUID>
<SCHEME_GUID> (optional) Specifies the GUID of the power scheme
to display, can be obtained by using powercfg -l.
<SUB_GUID> (optional) Specifies 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.
-CHANGE, -X Modifies a setting value in the current power scheme.
Usage: POWERCFG -X <SETTING> <VALUE>
<SETTING> Specifies one of the following options:
-monitor-timeout-ac <minutes>
-monitor-timeout-dc <minutes>
-disk-timeout-ac <minutes>
-disk-timeout-dc <minutes>
-standby-timeout-ac <minutes>
-standby-timeout-dc <minutes>
-hibernate-timeout-ac <minutes>
-hibernate-timeout-dc <minutes>
Example:
POWERCFG -Change -monitor-timeout-ac 5
This would set the monitor idle timeout value to 5 minutes
when on AC power.
-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.

Duplicates the specified power scheme. The resulting
GUID which represents the new scheme will be displayed.
Usage: POWERCFG -DUPLICATESCHEME <GUID> <destination GUID>
<GUID> Specifies a scheme GUID obtained by using the powercfg -l.
If <destination GUID> 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>

be obtained by using "PowerCfg /Q."
<SETTING_GUID> Specifies an individual power setting GUID and may
be obtained by using "PowerCfg /Q".
<SettingIndex> Specifies which of the list of of possible values
this power setting will be set to.
Example:
POWERCFG -SetAcValueIndex <GUID> <GUID> <GUID> 5
This would set the power setting's AC value to the 5th entry
in the list of possible values for this power setting.
-SETDCVALUEINDEX
Sets a value associated with a specified power setting
while the system is powered by DC power.
Usage: POWERCFG -SETDCVALUEINDEX <SCHEME_GUID> <SUB_GUID>
<SETTING_GUID> <SettingIndex>
<SCHEME_GUID> Specifies a power scheme GUID and may be
obtained by using PowerCfg /L.
<SUB_GUID> Specifies a subgroup of power setting GUID and may
be obtained by using "PowerCfg /Q."
<SETTING_GUID> Specifies an individual power setting GUID and may
be obtained by using "PowerCfg /Q".
<SettingIndex> Specifies which of the list of possible values
this setting will be set to.
Example:
POWERCFG -SetDcValueIndex <GUID> <GUID> <GUID> 5
This would set the power setting's DC value to the 5th entry
in the list of possible values for this power setting.
-HIBERNATE, -H

Attempts to report reasons why sleep states are unavailable.
-DEVICEQUERY
Return a list of devices that meet the specified criteria.
Usage: POWERCFG -DEVICEQUERY <queryflags>

wake_from_S2_supported Return all devices that support waking the
system from a deeper sleep state.
wake_from_S3_supported Return all devices that support waking the
system from the deepest sleep state.
wake_from_any Return all devices that support waking the
system from any sleep state.
S1_supported List devices supporting light sleep.
S2_supported List devices supporting deeper sleep.

-ENERGY
Analyze the system for common energy-efficiency and battery life

[-DURATION <SECONDS>]
