• Screen brightness will not change

  Greetings.  I have the model SVE14A35CXH.  A new problem has arisen today: I can't set my screen brighntess.  It does not solve with manual controls (i.e., using the function key, or by accessing the settings of the bar charms, or by the 'Power Options' Control Panel).  Moreover, I observe without changing the brightness of the screen during the occultation/increase in ambient light, despite the fact that I have activated in the VAIO Control Center of automatic detection of brightness.  I am running Windows 8.1, and all of my updates seem to be current.  I would be grateful for any suggestion.  Thank you!

  I reinstalled the latest graphics driver, the latest version of the BIOS and I still cannot adjust the brightness of the screens (screen).

  The indicator appears but is grey.

  Thanks for any help, Paul

  Update on the screen brightness controls; went into the BIOS and reset on off action keys.

  Restarted and there was no change.

  I then uninstalled the drivers for the monitor and rebooted and the brightness setting now works again.

  Thank you all, Todd especially for assistance.

  Hi @weiwei17,
   
  Thank you for visiting the HP Forums! A place where you can find solutions for your problems with the help of the community!

  I stumbled upon your post on the laptop and wanted to help you! I looked in your question about your computer laptop 14-ac014tx HP and questions with your upgrade to Windows 10. Try to use the Windows Update Troubleshooter to fix the problem.

  Here is a document that shows how update the drivers that do not work correctly with Windows 10.

  HP has worked closely with Microsoft on developing for Windows 10. Currently there is no driver available for your system. You can try and check at a later date, because I see new drivers all the time.

  Here is a link to the HP Support Assistant, if you need it. Simply download and run the application and it will help with the software and drivers on your system that may need updating.

  Thank you.

• Dell XPS 14 brightness will not change / "Painting as" Image

  I just got a Dell XPS 14 Core i5 and the GeForce 630 M. I found that the brightness of the display does not change even if pressing the keys on the keyboard or adjust the slider on the screen the toggle to retouch the brightness comes. Thus, the keys work. I have updated the drivers for the 630M, chipset and Intel 4000 card. Also, I flashed the BIOS with the latest version. The Dell representative I talked to said that updating the drivers may solve the problem - it didn t. Then, through remote connection it did for me. No luck. So, what's the problem? Also, I have a weird and potentially related problem. All the images on the screen (bottom of screen, images in the browser, photo gallery, YouTube, etc.) have a look "painted" their. The videos are unstable and the images are very washed-out. Once again, after update, the problem persists. For me it is a hardware problem. Help someone!

  Thank you

  Type of system: XPS 14 L421X detailed description of the problem:

  The display is of poor quality with graphs, images, videos and texts appearing pixelated and grainy. The problem is particularly notable for graphics online / on the internet. The contrast is also apparently, make images appear as less detailed, almost like a screen 256 older colors. The problem persists when the video output is connected to an external monitor via a HDMI cable.

  The issue is subtle and may not be obvious to new users; Is why it can easily be neglected if not carefully read. I would recommend comparing the simultaneous side-by-side display of the same image on your computer and another computer files. In addition, display images at actual size of 100% in the comparison will help identify the problem. You should be able to see obvious color with gradients almost "oil painting" as artifact.

  After months of wasted effort with XPS support replace the LCD screen, install a new copy of Windows and video drivers, shipping my computer for the installation of Dell for 'analysis of expert' and even replaced all of the device, the problem has not been solved.

  A few days after updating my Windows to 8.1, I found the problem. Here is the solution: right click on the new button start click on "Mobility Center", under 'Color of the default' select generic color instead of splendid color. This will fix the problem.

• BlackBerry Q5 display on lock screen wallpaper will not change (with aprental controls off-road and without)

  The following took place in my quest to solve the meanless screen too high.  That's why I serched for several Blackberry World and internet screen savers.

  At some point, I downloaded a wallpaper of the internet where I have the image itself has been doenloaded in images and from there I clicked it and got options to use as paper screen wallpaper and wall of a lock.

  Later, I found the other wallpaers and succeeded him.  However, it has not changed the lock screen wallpaper.

  I did it with the parental control is turned off.  Later, when I changed the wallpaper that's not going away from the lock screen, the icons were changed and new wallpaper was left out leaving a black background.

  But this process has not changed the lock screen.

  I deleted the uploaded image independent of photos and the lock screen still shows the wallpaper I'm changing.

  Any suggestions?

  Thanks, I've thought about it.  It's the fact that the original file was set as wallpaper screen and lock of bot.  I changed just walpapers thanks walpaper software added to the Q5.

• G70 screen resolution will not change

  HP G70 - 257CL running Windows Vista Home Premium SP2

  Mobile Intel 4 Series Express Chipset Family

  Have this second hand with a broken screen. Until I could get a new screen, I used the HARD drive in another notebook successfully. Now reinstalled in the G70, have everything works fine except the screen resolution.

  Reports adapter Device Manager works correctly. I uninstalled and reinstalled, updated the drivers. But no matter what resolution to choose for the screen, it remains the same.  I've currently set to 1440 X 900, 32-bit color, refresh rate of 60 Hz. But what I get is closer to 800 X 600. And it stays that way, no matter what I put it to.

  To the best of my knowledge, I uninstalled all drivers associated with the other laptop, so there should not be anything interfere. Thanks for any help, that all the world can offer.

  Hi Barnaby,.

  It doesn't sound like an exorcism is necessary. From all I have seen and know the computers that he shouldn't do that. Before you call the Ghostbusters or a priest try connecting an external monitor to see if you have the same problems.

  I installed the last dryers and since then I am unable to change the brightness of the display using the function keys. I installed several driver updates from where it is difficult to know which driver is causing the problem. The pointers in this area would be a good help.

  The latest driver Intel HD (from Intel) is originally this issue. Uninstall and reinstall the driver provided by Lenovo.

• Satellite Pro L450D black screen and will not respond to any keys

  Hello

  My niece has used his Toshiba L450D for almost a year now and he really liked it, who was until last month. She turned on her laptop and when she presses the button of the mouse, the button cracked and he fell into the laptop.

  Now my brother contacted Toshiba and I was told because it is under warranty it might return for repair because it was a common fault. Then he he packed in loads of air bubbles and a box to make sure it was safe.

  A few weeks later he came back repaired but we were all shocked that the laptop was put in a very loose box and you could hear this rattling noise. When we turned on the battery was flat and we had a new boot menu.

  As she installed it Windows 7 laptop would boot directly into Windows 7, but now after the repair of the laptop shows a menu black screen with as follows:

  + Windows 7 +.
  + Recover Windows to Factory Settings [active EMS] +.

  So we started in Windows and everything went well, but now after 5 or 10 or even 20 minutes, laptop displays a black screen and will not respond to keys or mouse movement. There is nothing on the screen its just black.

  I started in SafeMode (which was more difficult with the new menu) and it does the same thing. I even managed to do a virus scan quick who took 3-4 minutes and was clean.

  I would like some advice on what my niece is very angry, and it's difficult to explain what is happening to a child in the primary school.

  Any help would be grateful.

  Hello

  Have you tried the option of HARD drive recovery?

  If this is not the case, try to set the notebook back to factory settings using HARD drive recovery.
  Turn on the device, press F12, choose repair my computer, then select Toshiba HDD recovery.

  I hope it will work!
