Volume/brightness screen does not appear

I wouldn't change anything on my laptop. I've closed, went to bed, it opens in the morning to find that when I pressed the volume or brightness setting the buttons would not display the icon in the middle of the screen. I downloaded and installed this menu stupid mediasmart smart who is so smart that it won't launch yet, so a lot of good that did, but since he worked last night, and suddenly it stopped working, I guess it wouldn't even really force me to download something like that because it was working fine beforehand. DV7-6135dx Windows 7 64-bit. The changes in brightness and volume, but it will not appear in the display.

Hello

Download and reinstall the HP OSD utility at the following link.

  • BlackBerry Q10 connection screen does not appear

    I have a Q10 and I can not log on screen to display.  When I click on the high background to unlock the screen, the screen came as usual, but in the upper part, the media volume is displayed. When I go to swipe to get the log to the screen the screen cleared all my alerts, but the login screen does not appear (although the display of the media volume is still there).  I plugged it in to see if that would do anything and now see a message that says "charging your battery more quickly, use the charger supplied with this device" but I was.  Any ideas?

    Good try to pull the battery to reset the phone.

  • When I log into Windows, the login screen does not appear, how can I fix?

    I am running Windows XP Professional.  When I start my computer, it works fine.  I can log on and have no problem.  Unfortunately, when I log into my profile, Windows logon screen does not appear.  I use the log on screen where you have to manually type your user name and password.  The HP wallpaper happens, but the log in box does not work.  Better yet, it is not always the case.  I logged on and outside several times without any problems to come back later and find the log in box missing.  The only way I can solve the problem is to manually shut down the computer using the power button then restarting him.  I have no idea why this is happening or how I can fix this problem.  Any ideas?

  • the resume session logon screen does not appear

    This happened after I installed windows essentials. Less, it's the only thing that has changed on my computer.

    Since then, my screensaver snaps but the logon screen does not light when I touch the mouse or keyboard. Everything is there for anyone to see.

    Help, please.

    I wonder if the screensaver is actually attractive.

    You use a screen saver image rather than a screen empty?  If this isn't the case, could you then temporarily for testing purposes.

    Go to control panel, Options power, active {power plan} change plan settings, turn off the screen and then set this for an hour or more, then you can be sure that it is not getting involved in this problem.

    Try this: -.

    1 if the screen saver is really attractive, but the connection does not work then it means that at least one aspect of the power options is not safeguarded by the system.  Are the other settings in power options, plan {power} active settings change, change of plan avancΘs, [you will have to click on "view the currently hidden settings] all be registered that you put them? Also, make sure that all these 3 parameters [above] still have their settings correctly.  You must be bored watching the. If the settings you equip & registered do not correctly appear in the advanced power management when you watch them again later to see this MS fix

    When you configure power options for the active power plan in Windows Vista or in Windows 7, the changes do not appear in the Power Options item in Control Panel

    2. If the screen saver is not actually engage then go on Panel configuration, device, Manager display - check for error messages then make a right click & Update drivers or go to the manufacturer of PC / display card manufacturer & install their last update.

    Beyond that, I can't think more away from the useful suggestions.  You've probably already tried SFC & found that he picked up nothing.

  • Windows XP logon screen does not appear

    Laptop of my colleague was recently hit by the tdss rootkit malware.  I think I could clean out of his system.  When trying to load the computer out of safe mode, the Windows XP splash screen appears, he will then travel to the blue screen (BSOD no), the pointer of the mouse will appear, but the login screen won't come.  How can I get this problem so that the computer can be used again without having to do a low-level format?

    I've used the Windows Recovery Console to extract a new copy of the kernel32.dll file, but the problem remains.

    Hey

    I wish your problem which was simple. return to safe mode and go to control panel, administrative tools, Event Viewer on and click on system. Now you should be able to see all kinds of errors publish and republish when replying again so that can see your problem.

    It sounds like your windows for some reason any download some drivers painful, which is why the long delay for your account download. You may also check your registry too. I wouldn't you recommended changes before saving your date and knowing your way around.

    On the command prompt type: housing (MRT.exe) If you missed to clean malware, let him scan window clean from any virus remains. Parderogationauxarticles how to clean tdss rootkit and with what?

    When windows has finished the Scan, Type Run: (msconfig.exe), the utility configuration system to select diagnostic startup or selective startup which means choose what system services or start to download when windows restarts starts. I recommend for you to disable all non-microsoft services and all the commissioning.

    Restart the computer, you should be able to access normal account.

    It's not over I have difficulty but only first step setting... good luck.

    P.S if tool (MRT) does not work it means that your friend didn't update its windows xp.

  • The keyboard on the Windows Media Center screen does not appear when I hit the enter keyboard key!

    I searched through the internet trying to find a solution to this annoying problem: after change to enter the registry and the application of the value entered for showOskOnKeyboardEnter under MCE. PerUserSettings, I always have problems serious on-screen keyboard to appear by using the key "Enter" on the keyboard.  I managed only a couple of times to get the OSK to appear among the dozens of attempts, however, I am unable to recreate the actions - is absolutely not stable.  The only area that reacts to the 'Enter' key is looking for music.  All the fields in the section of Netflix and movies search fields are unresponsive.  Not even works tap triple function.  The only compatible and possible way to have the OSK appear is to double click on the field - that does not work given that the goal is to have an IR remote with the Media Center application interface.  The button 'OK' on the remote control is mapped to the Enter key (except if WMC has a key code value for the 'OK' button).  Help, please!

    I had this problem and it was very frustrating.  The posted solution did not work for me initially.  What I've discovered, is that you have closed Media center before editing the registry.  If you change it while it is open it does not pick up the change and then save settings (i.e. with showOskOnKeyboardEnter = 0) when you close.

    Then...
    1 close Media Center.
    3. Open Media Center.
    Should work now.
  • Logon screen does not appear for public wifi

    I recently bought two Macs (Macbook Pro and Macbook Air).

    When I connect to wifi, which requires a logon, the Macbook Pro works fine. The Macbook Air does not work. It connects to the network, but when you open a browser, it says that you are not connected to internet (which is true, as did no logon).

    Forums offers various ways to approach this (try to force the login screen by entering the URL, look at the DNS settings, enter http://192.168.1.1 etc etc) but none of these work.

    I am lucky to have two Macs and I watched the network settings, Notification etc settings and they are (essentially) - things the same as the Mac address are obviously different.

    Two Macs are OS X El Captain (Version 10.11.4).

    Can anyone help as the Macbook Air is not very useful if I can't access public wifi?

    And if anyone has the definitive answer, I think it would help a lot of people.

    Thank you very much.

    How are you connected to the router? What's an auto assigned DNS or that you must do it manually.  If it's self assigned, remove the wifi settings in the preferences system, network. Network / airport / advanced, under the airport click Network in the box, then the negative pole. Then close and open the airport icon in the top menu. Make sure that the airport is on. Click on join the network, and then follow the instructions.  you will be asked for the name of the network and security. then your network password.  Do of course, don't forget that this network is enabled. You are basically removing the network in system preferences and starting over.
