Hi AG_8055,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your HP Pavilion 15-n205tx Notebook and brightness not working correctly.  You could try a refresh on Windows 8 stops anything that has not closed correctly. You could try a BIOS update. The HP Support Assistant will help you install the drivers and software for your machine. It will locate the correct driver update for the brightness. Here is a link download  the HP Support Assistant if you need it.
Hope this helps you out.
Thanks.

  • How to adjust the brightness on Tecra 8100?

    hello there i'm using a tecra 8100 and I just cant find where to adjust the brightness which is really giving me problem. Please anyone help.

    > Since I install my Windows XP, I can't use my Fn button.
    @pardhi
    You have installed the OS manually and you didnt use the Toshiba recovery CD. Am I right??
    The fresh Microsoft OS does not contain the Toshiba drivers and therefore the drivers for the FN functions must be installed additionally.
    The problem is that you will not find any drivers for the Windows XP for the Tecra 8100.
    The WinXP drivers are not available and therefore you cannot use the FN keys

    sorry for the late reply, here's the things you can try , try rolling back the driver or you can access the registry to adjust some values here's the step:
    1- install latest driver of your graphic card
    2- This step will fix the problem:
    3 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]

  • How do i adjust the brightness on my screen? it's dim like when the power cord is out.

    After my wife had the laptop out of the house today, I plugged it back in and the screen brightness is very dim...like what it looks like when the power cord is not in...usually, when I plug the cord back in, the screen becomes brighter...that has stopped. Any ideas to fix?
    thanks.

    Hi,
    Here are some common ways to adjust the brightness.
    Open windows Control Panel, open Windows Mobility Centre and adjust the brightness here.
    On a lot of notebooks, tapping f3 will often increase the brightness ( with f2 reducing it ).
    Open windows Control Panel, open Power Options, click Change Plan Settings next to your selected power plan and you can adjust the brightness here.

  • When I went to adjust the brightness on my phone, the screen went black.  I have tried everything...resetting, turning off/on, charging, and restoring.  I can see the "unlock" page and the "passcode" page, but when I enter the passcode, it goes dark again

    When I went to adjust the brightness on my iphone, the screen went black. I have tried everything I can think of and have read online to try....resetting the phone, turning it off/on, charging the phone, and restoring the phone.  I can see the "slide to unlock" page and the "enter passcode" page.  When I enter the passcode, the screen goes dark again.  I can't even answer calls.  What should I do now?

    If no change after restoring the iPhone as a new iPhone or not from the backup, the iPhone has a hardware problem.

  • How to adjust the brightness of a second display connected to iMAC 2012  by Apple Mini DisplayPort to Dual-Link DVI Adapter?

    How to adjust the brightness of a second display (Dell 3007WFPHC 2560x1600 dpi) connected to 27 inch iMAC 2012 through thunderbolt port by an Apple Mini Display Port to Dual-Link DVI Adapter?

    Macs control computer by USB.  With a non-Apple display, you will have to use the brightness control on the display.

  • I have to keep adjusting the brightness

    I have a mid 2010 Macbook Pro 13".  For the past several days whenever it has gone to sleep or when it has been turned off and restarted I have had to go in and adjust the brightness.  When it comes back on the brightness is nearly all the way down.  It has never done this before and I don't know why it has started now.  No new programs have been installed to make it do this.

    I tired that.  I even unchecked it and then rechecked it.  The box is checked when I open the display preferences to turn up the brightness after it has dimmed.  The only thing different is that the slider is all the way to the left which is the dim position.  So I slide it back to where I like it but like I said it goes back to dim anytime it has been off for a while.  Thanks.

  • How do you adjust the brightness on a Thunderbolt Display

    How do you adjust the brightness of a Thunderbolt Display attached to an iMac ?

    I had this peculiar ‘issue’ hooking up to my MacBook Retina when my Thunderbolt Display was delivered but Applecare  - thanks Andrew - got me there. It seems daft!
    The Thunderbolt Display Brightness slider IS there – you just have to know how to make it show up.
    At initial set-up of the Thunderbolt Display [or if the Brightness slider is ever not visible in the System Preferences> Thunderbolt Display window], so long as the Thunderbolt [external] Display and the Macbook Display are ‘mirrored’ I can control the Thunderbolt [external] Display via my MacBook Retina Brightness keys [F1 & F2] – or by the Brightness slider that THEN appears in my System Preferences>Thunderbolt Display window. Once set up the Thunderbolt Display System Preferences Window continues to show the Brightness slider but I occasionally lose it if my MacBook has been disconnected from the Thunderbolt Display for some time – and I then have to start over.
    So:-
    Apple menu >
    System Preferences>
    Displays>
    Click Arrangement [at the top]
    Click Mirror Displays [at the lower left]
    That then gives me-at-least a Brightness slider on the System Preferences> Thunderbolt Display window [as well as on the Built In Retina Display window] and I can then adjust them independently.
    Oddly, having set this up just once the Brightness slider then remains on my Thurnderbolt Display and I can control it [and my MacBook Retina Display independently]. Occasionally I lose it again and have to start over.
    Hope this works for others.

  • When I use the "snapshot tool" some images are very light. how can I adjust the brightness....

    I have windows 7 and Acrobat X Pro.
    When I use the snapshot tool I cannot figure out how to adjust the brightness on that image? On my old computer a picture tollbar would pop up. A lot of images are very light and I need to darken them.

    My not be much you can do. However, I would just clip them into my favorite image tool (in my case IrfanView) and adjust there.

  • How can I adjust the brightness of my old Apple 24" LED Display?

    How can I adjust the brightness of my old Apple 24" LED Display?

    Jacob,
    Thank you for the quick response. I opened both the TIFF and the EPS in Illustrator. I used the Eyedropper tool to get the CMYK values of the color of the text part in the TIFF, then I went back to the EPS and selected the text and input the CMYK values in the color tab. I know it's not precise, but it's close enough. Could I have done this better?
    Yes, I have access to Photoshop but I haven't tried using it with vector files. I am really new to graphic design and I need all the help I can get. Thank you!

  • My display is dull, how do I adjust the brightness?

    I have an iMac, the screen has gone quite dark (as if in sleep mode)  I have to sit in a darkened room to see it properly. Have I hit the wrong key or key combination of keys? How do I adjust the brightness? Help

    If you are still on 10.4.11 (stongly doubt it) you probably have wired keyboard, the F3 key is for brightness. Also check System Preferences - Universal Access - Seeing and check there too.
