I have a Sony Vaio laptop, and it runs windows 7. I know I can adjust screen brightness from the control panel, but I want to force it to be even brighter. Is there a hack, or a way to do this from command prompt?
OK, so here's what I did:
The two commands for setting any power settings are
Then we need three GUIDs. Find them by running
..and so on.
Now you need to find and write down:
Now put your three GUID values plus desired brightness in percent - lets say 10% - like this:
And... nothing happened for me! The brightness didn't change! By executing
And voila! my screen brightness dimmed to 10%!
I made a batch file that works for english which uses the method above. http://aarongiera.com/change_brightness.bat
It works, but only on a scale of 0-100. It can't any lower or higher brightness the leds are capable of disappointingly.
