    Lock Brightness settings?


    Well, I have installed Windows 8 on my laptop, but was wondering if there is a way to lock the screen brightness.
    The reason being is that family members constantly mess with the brightness and sometimes leave it at 100% when using the battery. I basically want to extend the life of the battery if it is possible by disabling or locking the screen brightness at a certain level.

    Hello Ion,

    Sure, you could specify a default setting for them in group policy (gpedit.msc), at the location below.

    Code:
    Computer Configuration -> Administrative Templates -> System -> Power Management -> Video and Display Settings

    Hope this helps,

    Thanks, but wouldn't it still be changeable using the function keys on the keyboard?

    I'm not certain about that. I don't have any to test with.

    locking is impossible I think. it is changeable and I think it is very easy and takes few seconds to set back via function keys
