Brighness issue after updation on Window 8.1

I have HP Pavillion g6 1202-tx Notebook PC, recently updated to Windows 8.1. Since then i am not able to adjust my screen. It's really ridiculous. I have tried to google it, but can't find any solution. Plz any body can help urgently.

Hi sonu4486,
Welcome to the HP Support Forums!
I see that you are having some trouble with brightness on your display after upgrading to Windows 8.1. One thing I am unclear on, is whether your issue is only with brightness of the display, or if there is also some other trouble you are having with the display as well. For now I will proceed with the brightness issue you mention.
Here are some HP documents I found that may be helpful related to brightness issues:
Resolving Problems with the Brightness of the Display
Display is Dim During or After Startup or Boot
Here are some other HP sources I found that may also be helpful to you.

  • Acer Aspire V5-531 Dolby Advanced Audio driver issues after updating to Windows 10

    After upgrading to Windows 10 I was getting an error on loading Windows media player which indicated that: The current Dolby audio driver version is 7.2.8000.17 and the softwareapplication expects driver version 7.2.7000.7. Please install a valid driver and application combination  Although Windows 10 has probably updated your driver to the latest version of the driver (you can check this in device manager for yourself) but the Dolby Advanced Audio V2 application which was supplied by Acer (not Dolby) has not been updated to the corresponding latest version. So, you need an updated version of Dolby Advanced Audio V2 (Version 7.2.8000.17) Acer have not published an updated version. Looked all over the site coudn't find it.  My solution was to remove the error was to uninstall the Acer version and replace with the correct version downloaded from the Lenovo site below. http://support.lenovo.com/us/en/downloads/ds028945  I'd wanted to make sure it was the same software, so I tried without uninstalling first and it refused as a version was already installed. So that was reassuring. Thanks for the archived post below pointing me to the softwre on the Lenoveo site at the Lenovo site. I'd looked all over the Acer site for it. http://community.acer.com/t5/2013-Archives/how-i-solved-the-dolby-realtek-audio-problem/td-p/103157  There are warnings on the page above not to use the Lenovo version of the software because of 'tuning', but my audio sounds just as good as before and the error is now gone. Without it the Dolby would have been uninstalled so it seemed a reasonable punt to me. Disappointed in Acer, will buy a Lenovo next time...

    Hi, The only driver that ever worked properly with Dolby was the driver for The V5-552G on windows 8 (not 8.1) This will work on your computer even if different model... the new driver on the Acer site for winodws 10 has not work either. So the one I´m using is: Audio_Realtek_6.0.1.6878_W8x64_A To Download the Driver and Software needed Go to: http://www.acer.co.in/ac/en/IN/content/drivers and Go: Ultra-Thin / Aspire / V5-552G To get dolby to work: 1. Uninstall the current driver, and any software related to it (the dolby software) 2. restart 3. Install the driver for windows 8 (in my case it never installs dolby automatically, I´ll explain how to do it manually below) 4. Restart twice (yes, I always had to restart twice after the install otherwise manually installing dolby would not work and I got an error when trying to run the install) 5. In the driver folders you downloaded and unzipped go to the folder "PCEE4" and run "DolbyAdvancedAudio.msi" 6.If you dont get the "Install PCEE" error, restart and you should be able to enjoy dolby (when its not acting up). If you get the error then you may have not followed the instructions properly. Go back to step 1 Good luck

  • Store issues after updating to Windows 8.1 Update 1. 0xc03f42e5 / 0xc03f424e

    On my new laptop I was installing store/modern apps just fine earlier tonight, now since the update to the new 8.1 update the Store has become very unstable. When I click install on an app in the store, I get the loading animation at the top for a very long
    time, then the store closes. It does however add the app to my app list, though in an "Error" state.
    If I click on this app, I get the error "This app can't install. Check the Windows Store for more info about Adobe Photoshop Express.", followed by a link to "Go to the Store". If I click the link, it takes me to the Installations screen
    where I see this app (and others I've tried to install), all with "This app wasn't installed - view details.".
    Clicking on that link gives me "Something happened (how very specific of you Microsoft) and this app couldn't be installed. Please try again. Error code: 0xc03f42e5".  I've also had error code 0xc03f424e too. Bizarrely, neither of
    which bring up ANY results on Google or Bing. Have I found a brand new bug here?
    I've tried rebooting, reinstalling my NIC and Wireless NIC, doing a troubleshooting on Windows Update (which did say it fixed stuff), a sfc /scannow. The only thing I've not done that I can think of is to create another admin user and delete the profile
    of this user, because that's a hassle I'd rather not have if I can avoid it.
    Any MS employees here care to lend me a hand please?
    Edit1: The error code that the Windows Update troubleshooter indicated, 0x80070490, pointed me to an article that recommended I run the following commands:
    DISM.exe /Online /Cleanup-image /Scanhealth
    DISM.exe /Online /Cleanup-image /Restorehealth
    The first of which is running now, though after 5 minutes it's still at 20% so might take a while.
    Edit2: Well the first above command said it found no problems after about 20 minutes. Am running the second restore one though anyway, just in case.

    Hi,
    Try this command to fix your problem:

    http://blogs.technet.com/b/ouc1too/archive/2013/10/19/windows-app-store-doesn-t-load-after-8-1-upgrade.aspx
    or, you can use WSreset.exe tool, or manually trying to clear the cache from the Windows\SoftwareDistribution\Download folder.

  • After updating to Windows 8.1 the Webcam in my Inspiron is gone and Imaging devices missing in Device Manager

    my webcam in my Dell Inspiron 3521 was working fine with Windows 8.  After updating to Windows 8.1 the Webcam in my computer is gone and the 'Imaging devices' is  missing in the Device Manager.  how can I get the Webcam back?

    After updating to windows 8.1 my wire less internet connection is getting disconnected intermittently .I am unable to predict the frequency or time
    period this is occurring.But now i am really struggling to use the internet.I have tried my laptop vendor support and Microsoft support both failed to provide a solution.Please help me to resolve.I have installed the Wifi driver from real tek site many times
    ,but that is not helping.kindly provide me the guidance.
    when i searched in internet i am able to see many people are struggling with this same issue .

    Hi, 
    You can refer to this blog, and try to roll back to the older version of network adapter driver to check the results. Other suggestions can also be used to troubleshoot your issue.
    Windows 8.1 Wifi showing "limited" or "No Internet Access"
    http://blogs.technet.com/b/dennis_schnell/archive/2013/08/31/windows-8-1-wifi-showing-quot-limitied-quot-or-quot-no-internet-access-quot.aspx
    Meanwhile, please check with the manufacturer of your router to update the firmware.
    If the issue persists, please help to collect following information for further research: 
    1)            Enable RAS Tracing on the client. 
    -              Over an Administrative command prompt. 
    -              C:\> netsh ras set tracing * enabled
    2)            On the client enable the following log as well:
    -              Over an Administrative command prompt. 
    -              C:\> netsh trace start scenario=netconnection capture=yes tracefile=c:\net.etl
    3)            Now, turn off Wireless adapter on the client and Turn it back ON for making it to authenticate. Once it fails to connect to the Wireless network, proceed to the next step.
    4)            Disable RAS Tracing on the client. 
    -              Over an Administrative command prompt. 
    -              C:\> netsh ras set tracing * disabled
    5)            On the client disable the following log as well:
    -              Over an Administrative command prompt. 
    -              C:\> netsh trace stop
    6)            Please provide the following files:
    From the Client:
    a)            ZIP folder of C:\Windows\Tracing
    b)            C:\Net.etl and C:\Net.cab
    Upload these files in SkyDrive and post back the shared link.

    hallo
    after i done the Windows 8.1 update my graphic card is giving me some problem.
    occasionally my desktop become black for 1-2 seconds and the background disappears.
    I've update all drivers.
    the problems started after the update to Windows 8.1

    driver version: 13.150.102.0
    thanks for support

    Hey @jdudleyjones ,
    Welcome to the HP Forums!
    I understand the card reader for your notebook is no longer working after updating to Windows 8.1.
    You're probably right that it's a driver issue, however just like you I don't know which card reader you're using either.
    Can you please tell me which notebook you have? For information on finding your product and model numbers click here: How Do I Find My Model Number or Product Number?
    It would also help if you could tell me the Hardware ID for the card reader. Here's how you find it:
    Press Windows Key + X
    Click Device Manager
    Click View at the top and select Show hidden devices.
    You will most likely find the card reader listed under Other devices as an Unknown device.
    Right click on it and select Properties.
    Select the Details tab.
    Change the drop down menu to Hardware Ids.
    Note down the first ID in the list (as you'll see they're all pretty much the same regarding the Ven_ and Dev_ numbers which is all I need).
    Once you've provided this info I should be able to find the drivers for you.
    Look forward to hearing back from you!

  • Black screen after updating to windows 8.1

    After updating to windows 8.1 on my HP Spectre ONE 23-e010 All-in-One Desktop PC my PC wont turn on properly all i get is beep and a black screen ... I have to press and hold power on for almost 15-20 mins for my PC to actually turn on and by reading the issues others have been having with this update i would like to know how to get rid of the update

    Hello @emoakaely,
    I understand that after doing the Windows 8.1 update you are not able to access your computer and you are inquiring as to how to unistall it. I am providing you with an HP Support document: Using Microsoft System Restore (Windows 8), which wil walk you through how to restore your computer back to a point in time before you ran the update. This will in essence reverse the update for you.
    ***This will not affect your personal files it will only restore your computer's operating system back to before the update.
    I hope I have answered your question to your satisfaction. Thank you for posting on the HP Forums. Have a great weekend!
    Please click the "Thumbs Up" on the bottom right of this post to say thank you if you appreciate the support I provide!

  • Problem after updating to windows 10

    My laptop is HP Envy m6 1213 tx. Recently I have updated it to Windows 10. After updating to windows 10 my laptop slowed down. Even opening File explorer is also very slow. Not only File explorer every process and every application became slow.  Please suggest a solution to my problem

    Purple-Gecko...all that I can say is, "Boom!!!"  You are THE man/woman, whichever the case may be.
    The "netsh winsock reset" command worked like a charm for my machine (running Windows XP SP3).  I have had two weeks of frustration with this issue and finally found your post which got me back online with the iTunes store.  My problem accessing the iTunes store began once I downloaded and installed iTunes 10.5 in preparation to upgrade to OS5.  Once 10.5 was installed, I could open iTunes and access everything except the store (which prevented any of my devices from being able to sync). I followed all of the suggestions that I could find in Apple Support and the suggestions that I was emailed from Apple's support techs.  I unistalled all Apple software and reinstalled iTunes multiple times, and still could not access the store. 
    Your suggestion is the only "cure" that I have found.
    I thank you, my iPod thanks you, and my iPhone 4 thanks you for taking the time to post this fix.

  • Internet browsers do not work after updating to Windows 8.1.

    I have spent several hours researching my issue, performing fixes that have worked for others, but to no avail. I have talked with 3rd party tech supports, in addition to Microsoft tech support. I also recently spent 3 hours under remote access with a helpdesk
    employee. To no avail.
    My issue:
    Recently updated to Windows 8.1. Immediately following, none of my browsers work. Internet Explorer is entirely out of commission. Firefox and Chrome, however, interestingly, are able to open simple google pages: gmail, google maps, google search - I can
    even search things that I want and results will show up... they just will not load if I click on them. The error message when I click on "More" says something along the lines of "maybe it's your firewall or antivirus wrongly detecting Chrome...",
    and I think maybe something similar for Firefox. Explorer simply says that it cannot display the page.
    So, how am I writing this? I am currently booted up in Safe Mode, with networking. Apparently it works here, which I'm hoping indicates that the issue to resolvable.
    Remedies I have attempted:
    I have restarted my computer over 60 times in the past 2 days.
    I have troubleshooted the internet connection via the button that says "troubleshoot". It says it cannot identify the problem.
    I have executed various command prompts executed as administrator: i.e. netsh winsock refresh, advfirewall refresh, something to do with ipv4, ipv6, a bunch of "IP stack resets", etc, etc.
    I have manually added chrome, firefox, and explorer to my firewall exceptions, both via McAfee and via the Windows firewall system. Both simultaneously, one at a time, etc, every combination of this.
    I have uninstalled the web browsers and reinstalled them.
    I have unintalled my antivirus and reinstalled it, and checked in between.
    I have turned my firewall off.
    I have manually inputted some kind of DNS address (8.8.8.8 and 8.8.4.4) and/or IP address (forget exactly what was asked of me to input).
    I have gone to my "Manage Devices" and updated all of my network drivers, and attempted to revert to old versions of drivers.
    There are probably more things that I have tried, I just don't remember exactly and cannot list them. Most things you can find on Google pertaining to this issue, I've tried.
    Is there anything at all that anyone can think of to fix this situation? I am about ready to refresh my computer/do a systems restore/whatever to erase everything, factory reset, even (hopefully it works, because I've read that some people have issue, i.e.
    no previous partition found or something, or no recovery media present, etc, etc).
    Before I resign to this, PLEASE FOR THE LOVE OF GOD HELP ME.
    Also, may I please note here that given the sheer frequency of this issue around the web that I've found, I think it is absolutely ridiculous and irresponsible of Microsoft not to rectify the issue. This is even 3+ months following the release of the
    update; I always lag on updating such that bugs like these are fixed before I get on the train. This update has essentially reduced my multi-hundred dollar computer to an infantile calculator/solitaire/checkers/Microsoft office LCD screen. Not to mention wasted
    2 full days of my time. 
    Sorry, just saw red there at the end and had to vent my anger. Please help.

    Hi,
    I can imagine the inconvenience you have experienced. I will try to help you in fixing the issue.
    Please test this issue in the Clean Boot environment to check if there is some conflicts with network.

  • Syncing issues after updating to 10.3.1.55

    After upgrading to itunes 10.3.1.55, today, it no longer recognizes my iPhone 4. I plug it in, the iPhone makes its normal syncing noice. I get a prompt, like always about it recognizing the camera and how i want to handle it. I cancel it, as usual, and then it never shows up in iTunes. I close itunes, connect my phone and it does not start itunes as it normally should. No error messages, just no response. Can anyone help with ideas?

    I had the same issue, after updating to 10.3.1.55 it would error out saying something along the lines of not being able to read the catalog or something.  I think the error even states do a restore to fix it.  Last night that is what I did, clicked restore and then had it transfer all my items back.  I'm glad I had just synced my phone prior to the update so the restore was really current.

  • After updating to windows 8.1 PSE will not load

    After updating to windows 8.1 PSE will not load.  I have uninstalled and downloaded a PSE and installed several times with no success.

    sorry it's not my apple id. it's my icloud email/account. after i updated to ios 8.1.2 my icloud acct on my phone is wrong. it's using my old college email address instead of my current icloud account email. my old college email address *used* to be my apple id, but i changed my apple id to my gmail account a few months back. anyway i can't "sign out" or delete the icloud account bc it thinks my college email address is my icloud account and it  keeps asking for the password. so i'll type in the current password for my icloud account and it says it's wrong and i need to retry or change the password, which i've already done twice and nothing changes. probably bc its asking for the password associated with the college email address it thinks is my icloud acct.
