Cannot Adjust Screen Brightness after Windows 8.1 Update....i am using sony vaio laptop....i recently updated windows 8 to 8.1

    I have tried uninstalling the Graphic drivers, re installing from hp assistant, I even tried directly from Intel drivers but it is not letting me adjust brightness =( Latest driver version to my 4400 Gcard was 27/07/2015 I guess we have to wait since those drivers are win8.1 compatible only =( 
    Hey, I tried updating the driver, I googled something like intel graphic 4400 windows 10
    Then I found this link
    https://downloadcenter.intel.com/download/25150/Intel-Iris-Iris-Pro-and-HD-Graphics-Production-Driver-for-Windows-10-64-bit
    read at descriptions to see compatible chipset.  After I downloaded it started installing and the screen starting to do the "power off" think it does whenever you're installing video drivers et voila!  ´the brightness went down and now my "brightness up and down" keys are working ='3 
    I hope this help you guys  

  • Cannot adjust screen brightness in Windows 8.1 on my G50-45

    Hello there,
    I just bought my new lenovo and instantly upgrade the system software into Windows 8.1.
    Everthing looks fine instead of the screen brightness adjustment, i've downloaded the latest graphic drivers but nothing happened.
    The display adaptor section into device manager keeps showing up that the driver is Microsoft Basic Display Adaptor rather than AMD radeon R2.
    Thanks in advance guys.

    hi kostas-mi , ecountered that issue a month ago and was able to resolved it
    things you can try:
    1- you can roll back the driver back to its stock state, if this doesnt work ,  
    2- install latest driver of your graphic card
    3- This step will fix the problem:
    - go to registery by regedit and change the value to 0xf048
    [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000]
    "FeatureTestControl"=dword:0000f048
     OR
    [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0001]
    "FeatureTestControl"=dword:0000f048
    Dont fake the funk............

  • Cannot adjust screen brightness after BIOS update

    I was able to adjust my laptop screen brightness but after the BIOS update:
    https://bbs.archlinux.org/viewtopic.php?id=132077
    I'm not any-more able to adjust it by hitting F2 / F3
    Any good suggestion on what to use to manage volume, /brightness etc? or why now isn't working anymore?
    Thanks.

    HI,
    thanks for the heads up, however I think the problem could be related also to my keyboard layout.
    Current
    cat /etc/X11/xorg.conf.d/10-synaptics.conf | grep -i model     
           Option                 "XkbModel" "hpdv5"
    Actually my HP is dv6 and I see now that the keyboard is totally different:
    DV5 http://images.google.com/imgres?q=hp+dv … 29,r:0,s:0
    DV6 http://images.google.com/imgres?q=hp+dv … 29,r:1,s:0
    What Xkbmodel should I use?
    Currently available:

  • Have Upgrade Graphic Card Driver, But Still Cannot Adjust Screen Brightness and Sleep Button Not Showing After Clean Installation of Windows 8.1

    I have done clean installation of Windows 8.1 on my HP Pavilion G4.
    Then I realize that I cannot put my computer on sleep mode and cannot adjust screen brightness.
    I understand that those problems caused by the graphic card driver.
    My computer is running on AMD Radeon HD 6400 series.
    Thus, I manually search on internet and found a latest graphic card update on microsoft site that is claimed compatible on windows 8.1 (link: http://msdn.microsoft.com/en-us/library/windows/apps/dn344644.aspx).
    I've upgraded it into the latest one. I've check on Device Manager, the driver is running well.
    But my problem did not solved!
    Please give me the solution!

    Hi,
    How about go to Device Manager, then uninstall Graphic driver and restart your computer, system will install its build in graphic drver. You can have a try.
    In addition, access to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Brightness and set its value to 100 for test.

  • Cannot Adjust Screen Brightness with Fn Keys on New L540 (8.1 x64)

    Hello everyone. I just purchased a new L540 with Windows 8.1 x64 on it and have run into a problem I'm seeing is apparently common. While my other Fn keys work as intended, I cannot adjust screen brightness with them. Pressing the buttons just does nothing and the laptop is running at full brightness at all times, even when on the battery. I have installed the latest Power Management Driver and from what I can tell, there is no version of the Power Management Software for anything newer than Windows 7. I also have installed the latest Hotkey driver (in fact, I've installed all the latest drivers for this machine.) I read in another thread that this can be caused by the latest HD Graphics driver from Intel but I actually can't even install that driver (says my system is not supported) so I am still using the latest Lenovo provided driver.
    Can anyone please assist with this? I want to be able to quickly adjust screen brightness when on battery but I can't do that at present. Thanks!
    Solved!
    Go to Solution.

    I have the same problem with my L540. It started with the update of the BIOS to version 1.65. Because I didn't find a solution, I went back to BIOS version 1.64, where all the brightness options are there and work properly.
    You can download older versions. When on the page with the new drivers (http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS037285) go to BIOS Driver 1.65, then choose "learn more". At the end of the following page you'll see all the older versions.
    That you can install version 1.64, you have to change the "Secure RollBack Prevention" Option in the BIOS: Restart the Computer. When you see the option "To interrupt normal startup, press Enter", press Enter. Press once again Enter. Press F1 to enter the BIOS Setup Utility. Choose "Security" -> then "UEFI Bios Update Option" -> then "Secure RollBack Prevention". Change this option to "Disabled". Then press F10 to save configuration changes and exit.
    After restarting Windows you can install BIOS 1.64.
    Another possibility is to wait for the next BIOS version ....

  • Cannot adjust screen brightness

    I have a Lenovo G585 and after updating to Windows 8.1 can no longer adjust the screen brightness, it used to work fine. I also had a problem with sound after I installed 8.1 but managed to fix that.
    Adjusting the brightness from Settings > Brightness does not work, nor does adjusting brightness from Battery Life > Adjust Screen Brightness or by using fn + up/down key. 

    hi jackbeazley,
    Welcome to Lenovo Community Forums!
    Open Device Manager and open Display adater.
    Right click on AMD graphics and choose Uninstall
       Be sure to place a check under delete driver software for this device.
           Now Restart the computer and install this driver
     AMD Video Driver  
    Check if the Screen Brightness will work now
    Hope this helps
    Cheers!

  • Completely unsolvable: Cannot change screen brightness after I upgraded my ThinkPad's display.

    I have a ThinkPad X240 which came with a 1366x768 TN panel, I hated it and so after a while I upgraded it to an IPS 1080p display. It works great and looks fantastic except it's stuck on max brightness inside of Windows 8.1. I cannot change the brightness inside of Intel HD graphics settings or inside of programs like Display Tuner. It doesn't work in Windows 10 either. The weird thing is, I can change the brightness just fine inside of Ubuntu. I've tried uninstalling the Intel HD drivers and reinstalling them, I've tried switching the drivers to the Microsoft Basic Display Adapter, and none has worked. I feel like I've installed every single version of Intel's Graphics Drivers and that I've done everything and it still won't change the bloody brightness. NOTHING has worked except to just use Ubuntu, which is not an adequate solution. I've even gone as far as to update my BIOS and reset it to defaults, I've even pulled the CMOS battery. I've tried the version of the Intel HD driver from Lenovo for the X240 and I've installed the monitor.ini files. I've also just learned that during the Windows Boot Logo, the FN keys WILL change the brightness, but as soon as Windows is done booting, it stops working. This, coupled with the fact that brightness control works in Ubuntu means that this must be something related to Windows right? Brightness control works in BIOS. I've even gone so far as to try and change the brightness through CMD using powercfg according to this post. http://superuser.com/questions/472081/can-i-force-a-greater-screen-brightness-from-windows-command-prompt I'm really starting to lose patience now as it has been like this for 3 weeks and I can't be using Ubuntu all of the time, I honestly do not know what to do, it seems like this problem is completely unsolvable. Edit: I even got so frustrated that I switched off the laptop, installed the old screen, booted up Windows, and the brightness worked. Then (I know this is a bad idea) WHILE IT WAS ON, I pulled the old display and put connected the new one. And lo and behold, the brightness **bleep**ING worked in windows on the new display.

    try change drivers

  • How adjust screen brightness in Windows 7?

    I used to use a Windows 98 laptop up to 3+ years ago, but since moving to Mac have largely forgotten how Windows works. I now have Windows 7 on Bootcamp and can't see how to adjust screen brightness. Surely there should be an adjuster on the System Tray (that's what it used to be called) bottom right next to the clock. I'm on 20" iMac with Apple keyboard (the long one with number pad at the right).

    Does the keyboard have brightness controls on the F keys?
    If these do not work: try holding fn and using the F keys.
    If that does now work I have to ask: have you installed the bootcamp software? you need to make a CD (or usb stick) of drivers and software from OSX then boot into wiondows and run it.

  • Cant adjust screen brightness after reinstalling windows_DV7-4080us

    Need help with my HP DV7-4080us.
    I can't adjust the brightness of my monitor and it's soooo bright that it hurts my eyes. Tried using the function key but no response at all, please help~~
    Lily

    Hi Advance23,
    Thanks for your reponse I appreciate that.
    Yes, i have just reinstalled Windows 7 64bits home premium on mt laptop (and I believe it's the latest version and with most present updates). After the installation, all the funtion keys are not working, e.g. Brightness adjustment/volumn adjustment etc.
    I did some research before posting this post and followed the steps on "Resolving Problems with the Brightness of the Display" from HP website to try to fix this as well, however i did not have much luck.
    One thing I haven't try is to download the drivers for HP, as there are too many drivers out there im not sure which one to download, so if i'm going that way would love to have someone's professional guide of which one should I donwload in order to fix this problem.
    Btw, since the system is newly installed the HP support desktop usually appears before going into windows is not there anymore, don't know if this is relavent to the issue here.
    Please help me with this, I really need to get my laptop going but now with such a bright sceen I have to ware a sunglasses
    Thanks

  • F5 and F6 keys (MacBook Pro) do not adjust screen brightness after upgrade to OS X Lion

    Hi All,
    since "upgrading" my MacBook Pro from Snow Leopard to Lion, the F5 and F6 keys for adjusting the monitor brightness do not work anymore! No matter how I set the settings for the monitor, the keys do not work.
    Sometimes, the MacBook now just uses a low brightness and the only way to modify this is to open the system settings and change it there.
    Does anyone know how to fix this so that it works properly (like in Snow Leopard) ?
    Thanks,
    Kristian.

    The screen brightness adjustment is F1 and F2.
    You can also adjust in System Preferences > Displays.
    Regards,
    Captfred

  • Changes in screen brightness after Windows update

    I recently purchased my Lenovo IdeaPad P500. The screen was fine until an automatice Windows update occurreced. Now it is hard to see the screen because it has darkened. No matter what I try I cannot get it to brighten up and it is hard to view in well lit rooms. What can I do to correct the problem. I have tried all of the googled suggested out there with no success.  Please HELP!!!

    I don't see where to turn off the auto brightness feature in Win 8.1 on P500 Ideapad.
    But I think this laptop has other problems; the screen remains very dim even while booting up.
    Help!

  • Can't adjust screen brightness on Windows 7

    Running on my late 2011' MacBook Pro 15" with Windows 7 Home Premium 64-bit Service Pack 1. I have an AMD Radeon HD 6750M graphics card. I have tried uninstalling the driver and what not. I can't seem to find a catalyst that will work. It always tells me that I don't have a proper graphics adapter.
    This is my 3rd time posting this, I'm hoping someone will have an answer.

    Well, I should elaborate more on the methods I have tried. (Also I am using a MacBook Pro, however that doesn't matter really) I have tried uninstalling my graphics card driver in 'Device Manager', I have tried using catalyst to install the driver (I'm using an AMD Radeon HD 6750M), I have downloaded 'Windows Support' through Bootcamp and have reinstalled Bootcamp on Windows 7 and tried using the drivers provided but nothing has worked. I have even tried this, Control Panel > User Accounts > Change User Account Control settings > slide control to 'Never notify' > Reboot, with no luck.
    Also, thank you for the response.
