Batch File To Detect And Set Windows 7 Power Mode

Question

I would like to create a batch file that checks the current system power mode and change it if necessary. I have the following. What am I doing wrong? (it does not work)

@ECHO OFF

SET _CURRENT_POWER_SCHEME = POWERCFG -GETACTIVESCHEME

IF NOT %_CURRENT_POWER_SCHEME% == "Power Scheme GUID: 381b4222-f694-41f0-9685-ff5bb260df2e  (Balanced)"(
    POWERCFG -SETACTIVE "381b4222-f694-41f0-9685-ff5bb260df2e"

)

Thanks for the help.

From my experience with batch file scripting, if it exits even when you have a PAUSE that should be getting hit, it means there is an error that causes it to crash. In this case I think it's a few syntax issues, as well as how you are setting the variable. I played around and got this to work:

@ECHO off
FOR /f "delims=" %%a in ('POWERCFG -GETACTIVESCHEME') DO @SET _CURRENT_POWER_SCHEME="%%a"
IF NOT %_CURRENT_POWER_SCHEME%=="Power Scheme GUID: 381b4222-f694-41f0-9685-ff5bb260df2e  (Balanced)" POWERCFG -SETACTIVE "381b4222-f694-41f0-9685-ff5bb260df2e"

The "For /f..." line is usually the command I use to get the output of another command into a variable. It is normally for parsing through more complex responses, but it handles the -GETACTIVE command in this case.
