    Hello,
    my girlfriend has HP Probook 645 g1 and we are having problem with screen brightness. When laptop is being plugged in the slider works perfectly file. But when it runs on battery the screen brightness adjuster doesnt work. I have tried updating drivers, changing power plan and it still does not work. Does anyone has any idea what could it be?
    Thank you

    You can move the slider but on my laptop, you won't get any change in the brightness until after you click Save changes. Have you done that?

    So I have managed to solve the problem with a help by microsoft tehnician. The problem was that when windows updated somehow one folder in windows registry was deleted and by that the slider was disabled.
