Brightness Issue on my Samsung Laptop

    My screen brightness keeps defaulting to extremely dim when I unplug my laptop or don't touch anything for a minute or two. The brightness buttons on the keyboard do nothing, and the slider on the settings section of the left-hand pop-up menu only makes the screen go really dim if the screen is already bright and it will not let it be bright again.

    The only way I have found to make the screen bright is...
    1. Go to Device Manager
    2. Under Display Adapters, right-click Microsoft Basic Display Adapter and select update driver software
    3. Select Browse My Computer for Driver Software
    4. Select Let Me Pick from a List of Device Drivers on My Computer
    5. Select Microsoft Basic Display Adapter
    6. The screen adjusts and the issue is resolved

    This correction only lasts until I unplug my laptop or leave it idle for a couple minutes. So currently I need to do the above process a few times a day and my laptop is almost useless if not plugged in.


    ***On the device manager window under display adapters, there was a yellow triangle with an exclamation point in it next to my AMD Radeon HD 8600/8700M. Then, I updated the driver and it went away. The update did not fix this problem.

    Thank you ahead of time!

    You need to study the power options in Control Panel.
    If Balanced is selected, click on Change Plan settings.

    I tried changing the default brightness for the Balanced power option and checked it on the High Performance one as well. The Default Brightness on both is 100%. Nothing has changed.

    The yellow triangle with an exclamation point in it next to AMD Radeon HD 8600/8700M under Display Adapters has returned. It goes away if I update the driver but this does not fix the brightness issue.

    In Balanced power options > Change advanced power settings (blue link at bottom left) > Display change the 'plugged in' settings so the Brightness is 100% and it never dims or goes off.

    EDIT : Tell us what model Samsung laptop it is then we can look for the display driver on Samsung's website

    I tried what you said and it didn't change anything. I have the Samsung Series 7 Chronos np780z5e.

    I'm not sure how to put the screenshot on here, but I found all of the info including advanced settings

    Balanced Power settings (1st number is "On battery", 2nd is "Plugged in")

    Turn off display - 5, 10 min
    Display Brightness - 100%, 100%
    Dimmed display brightness - 50%, 80%
    Enable adaptive brightness - On, On

    My brightness goes down really low even if I just switch power plans (i.e. Balanced to High Performance) and I'm still not able to adjust brightness with the brightness slider.

    Thanks again everyone for looking into this.

    Keep it on balanced.
    This is what is causing all your problems: Change dim the display from 5 minutes to 1,2,3,4,5 hours or never for on battery and plugged in. (This will decrease battery time).

    Okay, I've done that, but I'm still not able to adjust the brightness. It's either all or nothing. If I try to adjust the brightness, it goes very dim, and I have to go through the aforementioned process to make it bright again.

    Exactly how are you attempting to adjust the brightness ?

    Right-click on the battery/plug-in symbol in the bottom right of my screen, click "Adjust Brightness", and I slightly move the screen brightness slider.

    Try setting the brightness to max in the Power settings then reboot and see where that slider is now, before moving it.

    All my netbooks have a key to adjust the brightness.
    On my Acers, I hold the function (Fn key) and press the left arrow to make it dimmer by degree and the right arrow to make it brighter by degree.
    There is an onscreen gauge that pops up and shows me what is happening.

    On my ASUS, I hold down the Function key and the F3 key makes it dimmer while the F4 key makes it brighter.

    Look over all the keys to see if you can control the dimness/brightness with the keyboard.
