Power configuration management using powercfg
Modifying the Active Power Plan:
Utilize the powercfg command to adjust various timeouts, such as monitor, disk, standby, and hibernate. For instance, setting the monitor timeout to 15 minutes when plugged in can be achieved with
1 2 3 4 5 6 7 8 | powercfg -change -monitor-timeout-ac 15powercfg -change -monitor-timeout-dc 15powercfg -change -disk-timeout-ac 0powercfg -change -disk-timeout-dc 0powercfg -change -standby-timeout-ac 0powercfg -change -standby-timeout-dc 0powercfg -change -hibernate-timeout-ac 0powercfg -change -hibernate-timeout-dc 0 |
0 = Never

Switching Power Modes:
View and set the desired power scheme. For example, to activate the high-performance mode, use the command
1 | powercfg /LIST |
Set the power scheme
1 2 3 4 5 | :: Normal usagePowercfg -setactive 381b4222-f694-41f0-9685-ff5bb260df2e:: High performancepowercfg -setactive 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c |
Advanced Power Settings:
To configure specific actions like the lid close action, use the powercfg command with the appropriate GUIDs. For instance, to set the lid close action to “Sleep” when on battery, use the provided commands.
1 | powercfg /QUERY |

We will have :
- setacvalueindex => for power management
- setdcvalueindex => for battery management
USB Power Management:
To ensure that USB devices remain active and don’t enter a power-saving mode, disable USB power management using the powercfg command.
