Laptop screen brightness won't adjust

  1. #31


    Hi all,
    Thought I'd create an account just to say thank you as I'm completely useless with computers and you helped a lot.
    I've got a Samsung Ativ book 4 and just got this problem this morning. I probably only got it so recently because I kept putting off updating to 8.1. Tried all the different ways to adjust the brightness but as much as the bar went up and down, brightness didn't change.
    I took your advice and looked into the Intel HD Graphics 4000 which I also found to be the culprit. I think what I've done is reverted back to a (way) older one and it seems to have solved it (although I'm not sure how long it'll last).

    Basically: Win+w -> device manager -> Display adapters -> right click Intel(R)...4000 -> Update Driver Software -> Browse my computer for older software -> Let me pick from a list of drivers on my computer -> Intel(R) HD Graphics 4000 Version: 9.17.10.2963 (I had 10.18.10.3368 before) -> Next -> restart.
    Seems to be working alright so far.

    Yes, that was the issue. Microsoft drivers provide only basic functionality, they don't support all features of the hardware. That is why I always prefer and recommend OEM (original manufacturer) drivers. It is better to have an old Intel graphics driver than having the latest Microsoft driver. This goes for everything else. Microsoft drivers should only be installed if there is none OEM driver. Unfortunately this is the case with many old printers as well. With MS drivers they just print on normal/draft and a very limited range of papers (usually only plain) while with OEM drivers they have special printing mode and support many paper types and sizes...

    Fortunately there is some backward compatibility with older Windows drivers, that is if you cannot find Windows 8, use 7 or Vista. At the worst case you can also use Windows XP (for 32-bit windows only). I would rather install an old Vista OEM driver than the latest Microsoft Windows 8 driver for the same hardware. I hope you get the idea...

    SOLVED FOR ME
    I had the same problem on two laptops from different manufacturers (Lenovo and Toshiba), but both running Win8.1. On both laptops the manufacturer's display brightness keys wouldn't work, the brightness control in the Charms bar wouldn't work and I didn't even have the brightness controls available in the Power Options plan settings.

    I found this after many hours of searching. Many of the suggestions have to do with the display driver, and while that worked for some people, I had tried every method that was different from the rest - until I found this one:


    1. In Device Manager (Windows Key + C --> Settings --> Control Panel --> Device Manager)
    2. Click on the arrow next to Monitors to expand it (my guess is you have "PnP-Monitor (Standard)" showing).
    3. Right-click that and select "Update Driver Software...".
    4. Then click on "Browse my computer for driver software".
    5. Then click on "Let me pick from a list of device drivers on my computer". You should see something similar to this:Click image for larger version Since I had PnP-Monitor (Standard) selected when I had the problem, I selected Generic PnP Monitor.
    6. Select whatever wasn't installed before and click Next.
    7. It will go through the installation and then you can click "Close".


    Now try your brightness keys on your laptop keyboard or the brightness control in the Win Charms bar.

    I really hope this worked for you because if you've gotten this far, you've probably been trying to fix it for a long time!

    Wow, amazing. For me, it was because I had another nonstandard monitor driver (for a remote desktop app). I have been dealing with this for months now, so this is great to finally fix.

    Odd that you'd have posted this when you did, given the thread activity and stuff. Maybe earlier in 2015 a windows update made it so that any deviation in the monitor breaks the keyboard function keys. Odd.

    Problem Fixed !


    I had the same problem with Windows 8 once and also with Windows 10. Both times I simply uninstalled the driver of `Display adapters` and then reinstalled it. Problem fixed !

    I was having the same problem on a clean install of Windows 10. I changed it from Standard to Generic and it worked immediately. Thanks!

    can you please explain to me how have you fixed it? how do I get to the drivers, etc. in steps?
    thank you!

    Go at Intel's site, select Support, Drivers, and then search for HD 4000 or whatever graphics you have. Download the last version of the drivers and install it. Restart the computer to take effect. Have a look at the Control Panel -> Device Manager (if you don't see the Device Manager, click View as -> Large Icons). Then expand monitor and see if it is "Generic PnP monitor". If it is not, right-click on it and select Update Driver. Then select the last option and again the last option. You should see a list of devices. If there is not "Generic PnP monitor" in the list, uncheck the box to show only compatible models. Then you should find it at the standard monitor types. Select it and proceed to install it, even if windows warn you it cannot verify compatibility. Restart your computer and you should be OK.
