Dell U2414h menu gone? Keys no longer work?

My Dell U2414h monitor is connected to the end 2012(El Capitan) Apple Mac Mini HDMI. After 1:30, I can't go back in the Menu of the Dell printer. It seems as if the touch buttons no longer work. It seems that if the menu is somehow locked.

The only thing dat will work is cut off from the power supply. After that work very good tactile buttons, but after a while or when I closed the Mac Mini, I can't go back in the menu. The Dell monitor is now also waiting because I cannot 'touch' the power button.

Someone know what I did wrong or is something wrong with the Dell U2414h or is it something in the Apple Mac Mini?

I asked the same question in the Forum and they said that it might have something to do with my Apple Mac Mini.

During the Forum, they gave me a solution that does not work for me:

Reset the U2414H and re - test
* Turn on the computer and monitor off
* Disconnect all cables from the screen, including the power cable
* Press the power monitor in 30 seconds button
* Plug the monitor cables for the monitor and the video card of the computer. There should be only one cable video connection from the monitor to the video card
* Turn on the monitor, then the computer

Note, as this model was not tested/validated on the proprietary Apple hardware, ports, and the software, you must also post on the Apple Forum of Discussions and see if they can offer an overview or troubleshooting steps.


Also does not work the solution in the manual to touch the power button for 10 seconds.


Someone knows what's the problem?

I think it is likely yo have a problem with the monitor. The video and does not interact with the onscreen menu/controls.

    Replace old hard drive with an SSD.  Now some of the keys on the keyboard stopped working.  Ex 'e' and 'b' keys no longer work?  Any idea what could take place in the disc replacement?

    Probably nothing, it's probably a fluke. Try resetting the SMC and the PRAM by iMac Intel SCM and reset the PRAM. If this does not work, try a USB keyboard to test, if it works then your original keyboard has failed and must be replaced.

  • Satellite M - PgUp PgDn, home and end keys no longer work

    All of a sudden these keys no longer work on the computer when I'm on the internet. They sometimes work in PDF files in Word, but otherwise, they do not work...

    Hello

    I agree with the user above. I think the keyboard needs to be replaced if certain keys n t work. The fact is that individual keys can t be bought, you can only buy the whole keyboard but it isn't so expensive.

    You can get a new keyboard to an authorized service provider. On the Toshiba page you can find a list where you can find an ASP.

  • Satellite M30 - two keys no longer work

    I have a very frustrating problem with my keyboard M30-106. Two of the keys no longer work IE, the Enter key and the button 'to '. I lifted the Board to see if it needs cleaning, but apparently not. Can someone tell me what I need to do to fix this problem?

    Hello

    If these two buttons are certainly defective there is nothing to see. As you know the essential mechanism is very small and very delicate. As much as I know it's not possible to order the buttons separately, but in my opinion, you should contact the Service of your country partner and explain the problem. Maybe they have a solution outside keyboard replacement.

    Good bye

    Hello benpierce25, try Firefox Safe Mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that temporarily disables hardware acceleration, restores some settings and disables add-ons (extensions and themes).

    If Firefox is open, you can restart Firefox Safe mode in the Help menu:

    • Click the menu button

      click Help

      then select restart with disabled modules.

    When the Firefox Safe Mode window appears, select "start mode safe."

    If the problem is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme or hardware acceleration. Please follow the steps described in the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

    The user.js file does not exist by default. If you create the file, forget it, if you don't have not create the file, and then remove the User.js file, to see if the problem goes away (some programs create and write to the file also).

  • Dell SK-8135 keyboard shortcuts no longer work?

    Hello!

    Thus, for some time I use a fairly old multimedia keyboard with some registry changes simple to customize shortcut keys multimedia fantasy located here:
    HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / Windows / CurrentVersion / Explorer / AppKey
    In the folder AppKey are 5 folders with the registry values corresponding to functions for 5 different keys. Sometimes in the past 3 weeks after Windows Update updated (I try to do often enough), Windows broken, or ceased to honor these values/functions.
    Example: the music button would open my Media Player of choice, instead, it opens Windows Media Player; and the electronic key should open a Notepad window, but instead opens with an error 'current assignment for this key is not available.
    It is worth noting that the "Microsoft mouse and keyboard Center" shows only one media key, and its modifications do not seem to be recognized by Windows.
    Oddly enough, I can get the shortcut keys to work again temporarily. If Windows has open Regedit.exe, the keys are functioning normally; However if I focus Windows away from this window (even if it is still open) they break again.
    These functions have the new registry values maybe? If Yes, where are they?
    Thank you
    SirGir

    Update (22/06/13): randomly found the answer! For all of you who have this problem in the future: just uninstall the "Microsoft mouse and keyboard Center", it is right in the menu uninstall programs. He fixed everything!

    The usefulness of keyboard Dell QuickSet controls special keys for of many valleys PCs, but I don't know if it has the same name on your PC keyboard combination.

    You should be able to confirm the name by checking in C:\Dell.  Mine has a subfolder called QuickSet conatins three files exe: QuickSet.exe, Battery.exe & MobilityCenter.exe.  Battery.exe & MobilityCenter.exe are the standard names, search for the third exe in the folder that contains them.

    If adjustment has been corrupted, then it will not make reference to these registry settings correctly and therefore your direct use of these parameters is inhibited as well.  Is not that I heard someone's done this before, but the logic of it seems to fit.

    Find a new copy of the quick adjustment on the site of Dell support, drivers & downloads for your model and install it.  You must not delete the existing one first unless the installation file or its instructions page say you.  I guess you have to put your custom in these registry keys subsequently as quick adjustment values installation probably crushes them.

    I can't explain the part about moving the slider of the RegEdit window - which is pretty weird.
