Brightness buttons does not.

Well, two control brightness buttons worked very well until I uninstalled the default graphics driver. Now, when I press it I always get the GUI cursor, but the brightness does not change. My brightness can be changed very well in windows power settings. I reinstalled the same thing, I uninstalled, reinstalled energy Manager, and it still does not work.

Does anyone have an idea how this can be fixed, thanks!

Too bad, it just randomly started working after like 2 hours...

    Hello:

    You probably need to reinstall the graphics driver.

    This package provides the driver that allows graphics Intel high definition (HD) in the notebook models that are running an operating system supported. If the video output high-definition multimedia interface (HDMI) is supported, this package also installs the HDMI Audio Driver.

  • My mute button does not work

    The button does not work everytime I try to put my phone on silent. I turn it down and it will automatically return to the sound, it activates again upward. What can I do?

    Hello Jackie101foever,

    Thank you for using communities Support from Apple!

    As I understand it, you can't silence your iPhone.  I have a suggestion that should help you with this.

    The first thing we want to do is to make sure that you have a current backup of everything on your iPhone.  If you follow this link, you will find instructions on how to make a backup:

    The backup of your iPhone, iPad and iPod touch

    If the silent button moves upward on its own, so you must do this checked by a service representative.  You can find the nearest one by looking here:

    Find locations

    If the button is stay down, but do not silence the iPhone then we want to restore all settings.

    Reset preference files resets all parameters that may be problems. This step will not delete your contacts, photos or personal information. It deletes all your preferences for Wi - Fi, Bluetooth, do not disturb, Notifications, general, sounds, brightness & wallpaper and privacy and removes your Touch ID & password.

    Do you this by clicking on settings > general > reset > reset all settings.

    Once you have done this, restart the iPhone and see if you are able to turn off the sound.

    Have a great day!

    Pavilion a1620n won't start, the fans are not running. PS on the light and Sun. Start button does not illuminate. EU tested ps and I was told it was OK. Disconnected from the motherboard except course before directed ps button and the cpu fan has become much brighter, but that's all that happened. Any suggestions on what to check? Checked with VOM push and he seemed to agree. Replaced the MB with the new Board of Directors, that didn't work either. Don't know if it was any good, it was a store Bulletin Board.

    All the indicators you mention leads to the PSU, not the Board of Directors.

  • By pressing the home button does not take me to the home screen of iOS 9.3.3

    I have recenly updated upgraded to iOS 9.3.3 and I noticed that pressing the home button does not take me to the home screen. The only way to get there is by using the creature of multitasking. (double pressing the home button) Also, some applications seem to freeze if turn my phone off and then turn it back on, or when I access it via the multitasking function. Can someone please help?

    Try a forced reboot. Hold down the Home and Sleep/Wake buttons at the same time for about 15 seconds, until the Apple logo appears. You won't lose anything.

    If a force restart does not help, try a system restore. First save your device via iTunes. Also import your photos on your computer and copy all the important data. Reconstruction of the support first test and test. If this does not help, you may need to restore as a new and reconfigure from scratch as the backup may be damaged. It is important to have your photos and your saved data separately from the backup. Here are the steps for a restoration:

    Hello, Firefox has been added in Firefox Beta 34.0. However, the Firefox Hello button does not appear in either Firefox, or using the Customize menu. Am I missing something or is this only available for select people?

  • "Back" button does not work and lost bookmarks

    I followed the instructions that Firefox has been extremely slow. He said my favorites would be saved and everything should work as usual. However, I lost all my precious Favorites, and now the back button does not work. She is pale grey all the time, and itls drives me crazy, that I can't go back to the search page. I have to type everything in full again.
    If I can't change it, I'll have to switch to another web browser, after being with Firefox for more years than I care to remember.
    I liked using Firefox and have recommended it to all my family and friends.
    I'm very angry on my favorites, because I used these regularly and had a few coordinates links and important model for my sewing and knitting, as well as time-saving links. Now, I'm completely lost without them.
    If this isn't the page said it would be saved, then I would not have changed anything.
    It's very frustrating and annoying, after spending months, where I wanted and now he lost get it all because of the wrong information. I am very anxious.

    You can check for problems with the database places.sqlite file in the Firefox profile folder.

    You can see if you can restore bookmarks to a JSON or a compressed backup of JSONLZ4 in the bookmarkbackups folder in the "Old data Firefox" folder on the desktop.

  • the 'Clear now' button does not not on web content caching

    I clicked on tools > option > advanced > caching of content, then clicked on the "Clear now" button > ok, nothing has shown that if the button does not work and there was no clear action.

    This button to clear the cache is probably broken because the current version of Firefox 32 has switched to a new service named Cache2 cache.

    This change will result in extensions that use the old cache service to stop working and its developer must update the extension.
    You can see the site of Add-ons to see if there is already a version available that maybe is not approved yet.
