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.

    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............

  • 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.

  • 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 ....

  • Feature Change: Remove useless adjust screen brightness button.

    Remove useless button for screen brightness.
    both buttons serve same function.

    Oh - that explains it better.
    You do know that not every computer using Windows 10 has a key available to adjust screen brightness though, right?  Or, as in the case of the Surface, if you don't have a keyboard, the only way to adjust the brightness is only the software one? 
    For you it might not make sense, but include ~1 billion more people, and I think they should just leave both. 

  • 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!

  • Using Windows 7 Display Won't Adjust Screen Brightness

    I am running Windows 7 Home Premium Service Pack 1 running on my MacBook Pro from January, 2012. My screen will not adjdust brightness. Not using the F1 & F2 hotkeys (The window will pop up showing I'm pressing up and down on the screen brightness but nothing changes) even going in to Windows 7 control panel will not change this. I can't change the brightness or turn off the display with the hotkeys or in Windows 7 settings. I have BootCamp installed. Any body have the same problem or know how to fix it. I've tried updating my graphics drivers but I don't think it worked.

    Take it to the Genius Bar. Your SIM might have an issue. The SIM is the part that manages power. My brother's Macbook Air has this issue. What haapens is the SIM malfunctions and gets confused on how much power to send to each part. Other symptoms include fan always running (even when its been off for a while), and you can't adjust the screen or keyboard brightness.

  • After the last upgrade of OS X Mountain Lion I can't seem to adjust screen brightness anymore. Why and how do I solve this?

    My screen brightness used to adjust itself and if not I could use f1 and f2 keys. After my last upgrade of OSX Mountain Lion, these do not seem to work. Does somebody know what happened and how I can return to the original situation?
