Power Configuration or powercfg.exe is a command-line tool in Windows that allows you to configure power system settings. It is especially useful for laptops that run on battery and will enable you to configure hardware-specific configurations that are directly not available through the user interface. In this post, we are looking at the most useful commands for PowerCFG.
Useful PowerCFG commands
powercfg or powercfg.exe can be directly used from the Run prompt or using PowerShell or the Command Prompt.
Here is the list of commands and options you can use, and it uses GUID, which is even more powerful.
- Change Power configuration for performance
- Tweak Basic Power Settings
- Enable/Disable Hibernation
- Ask for Password on Screen wakeup
- Change the power plan type
- Set hard disk timeout
- Change wireless adapter power-saving mode
- Change sleep timeout
- Set what happens when you close the laptop lid
- Change Processor Power State when on battery
- Set monitor timeout
- Change multimedia settings
Use them only if you are a power user, and comfortable with the command line.
1] Set Power configuration to High Performance
powercfg -setactive 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c
2] Tweaks the basic power settings
powercfg -change -hibernate-timeout-ac x powercfg -change -hibernate-timeout-dc x
Where x is time in minutes. If you type powercfg -change -hibernate-timeout-ac 5, then the computer will hibernate in 5 minutes.
3] Turn off or disable hibernation
powercfg -hibernate OFF
4] Ask for Password on Screen wakeup
powercfg -setacvalueindex 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c fea3413e-7e05-4911-9a71-700331f1c294 0e796bdb-100d-47d6-a2d5-f7d2daa51f51 0
(0=false, 1=true)
5] Change power plan type

10] Change Processor Power State when on battery
Use the following options to change the state.
- 0,1=power saver
- 2,3=balanced
- and 4,5=high performance.
Processor power state
powercfg -setacvalueindex 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c 54533251-82be-4824-96c1-47b60b740d00 68f262a7-f621-4069-b9a5-4874169be23c 4
Minimum processor state
powercfg -setacvalueindex 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c 54533251-82be-4824-96c1-47b60b740d00 893dee8e-2bef-41e0-89c6-b55d0929964c 100
