How do I read individual PowerCfg settings?

Question

If I run this command:

powercfg -SETACTIVE 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c

...I can subsequently run this command:

powercfg -GETACTIVESCHEME

...and it will tell me what I did. (It will output 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c.)

Similarly, if I run this command:

powercfg -change -monitor-timeout-dc 0

I want to know how I can query that. Is there some powercfg flag where I can read the current value of monitor-timeout-dc, and other settings like that?

This returns the monitor timeout (in seconds) to turn off. Note that i'm skiping 16 lines for DC timeout, if you want AC timeout then skip 15 lines.

@echo off
setlocal enabledelayedexpansion

set SCHEME=8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c
set VIDEO_GUID=7516b95f-f776-4464-8c53-06167f40cc99

for /f "skip=16 tokens=1*" %%a in ('powercfg -Q !SCHEME! !VIDEO_GUID!') do (
for /f "tokens=2 delims=:" %%c in ('echo/%%a%%b') do (
set /a "timeout=%%c"&goto break))
:break
echo/%timeout%
pause>nul

You can query any configuration. For a list of schemes use powercfg -list, for a list of guids use powercfg -aliases

Important note is that seconds are displayed in HEX values, not decimal. A value of 100 = 256 seconds. – Jason Faulkner Jan 22 '15 at 18:10

@JasonFaulkner You're right, but `set /a` converts the HEX value to Decimal value. – Rafael Jan 22 '15 at 18:38

Nice. I did not know it did this automatically. – Jason Faulkner Jan 22 '15 at 18:40

This is perfect. This is just what I needed. I've accepted your answer as correct, and I tried to give you the bounty right away as well; however SO says I need to wait a day before awarding it. – soapergem Jan 22 '15 at 19:18
