HP laptop - 14-ac122tu: no option to set the brightness of the screen

I recently loaded a Windows 7 64-bit OS and there seems to be no option to set the brightness of the screen. I tried in the power option and the f3 f2 keys. I tried a few things mentioned in some forums as uninstaling the monitor, but there seems to be no way of setting it. Am I missing some drivers? I installed the drivers in the link

http://support.HP.com/us-en/drivers/selfservice/HP-14-AC100-notebook-PC-series/8499318/model/8876444... .

Please help me solve this problem.

It's interesting that nothing works.

These files are from the ac122 support page!

Try this one...

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.

File name: sp72592.exe

If this does not work, try this one...

If this does not work, try the driver directly from Intel.  3rd file downwards on the left for 64 bit.

If none of the above, unfortunately, work I don't have any other suggestions for you to try.

  • On NEW laptop keyboard does not work after that the screen keyboard has been activated and then deactivated.

    Look at my friend got a new laptop and went through the whole upward. the on-screen keyboard has been activated which invalidates the real keyboard when the on-screen keyboard has been disabled the real keyboard has NO return. If this is a bug... Fix it. This is not a driver issue, it is not a user error. Stop giving people answers, trying to pretend like it's not not the OS when most people already know that it is.

    I'm sorry, but I didn't not new meant only one day.  And when I got my new laptop, one of the first things I did was to create a point of files, even a day later I had a restore to use - point and that was possible here as well.  I'm sorry it wasn't the case.

    If the system restore option is not available, do a startup repair, boot from the disk Installation of Windows Vista genuine (or one that you can borrow from someone) or a recovery disc.  Here is the procedure: http://www.bleepingcomputer.com/tutorials/tutorial148.html.  You may need to change the BIOS to do first the CD drive in the boot sequence to boot from the CD.  To do this, hold the screen that tells you the key F to push to enter the menu start or start of installation.  Push it quickly. Make the changes, save your work and exit.  Put the CD in the drive and reboot.  When you are prompted, press any key to boot from the CD.

    If you do not have a floppy disk, you can make a bootable recovery disk by using http://neosmart.net/blog/2008/windows-vista-recovery-disc-download/ with burning software like: http://www.snapfiles.com/get/active-isoburner.html and, of course, a blank CD.

    If this does not work, you can try to go into the BIOS during the startup (the key appropriate to push appear on the screen to enter the boot menu or boot installation - try them both in turn if both appear. It is possible that the BIOS contains an option to disable the keyboard (which may have been activated by the keyboard on the screen but not changed when disable you the on-screen keyboard) and you may need to re-enable manually.  There is a slight possibility, but it is an option to try.

    Another option to try is to set up a new user account that has never used the keyboard on the screen and see if the regular keyboard works when you connect to this account.  If so, you can simply treat the original as a corrupt account account and use the following procedures to complete the transfer.  To fix this use http://windows.microsoft.com/en-AU/windows-vista/Fix-a-corrupted-user-profile.

    I hope that one of these aid procedures.  I'm sorry if they seem to 'generic', but we do not really know what is the problem - especially since the system is new.  We try and identify the cause and fix the problem at the same time using the procedures available to us.  I suspect there's a registry tweak will correct this problem, but I went through the whole registry, and although I found several referencers keyboard, I could find no which seemed to control or not activate the main laptop keyboard (though it has been in one of the entries that has been encoded in binary that I couldn't read).  It's possible someone who knows more about the registry will respond to this issue with a proposal to amend (or perhaps another solution).

    I hope that one of the solutions I proposed works.  Please post back in all cases we will know whether or not to continue searching for an answer.

    Good luck!

  • Tecra M7: Unable to set the screen resolution to 1680 x 1050 on external screen

    I have a M7 and a 1680 x 1050 VX2025 viewsonic monitor.
    I can't set the resolution for external display in clone mode or dual mode.
    Infact I can not get any resolution of the screen to exit the M7.

    I tried this in Windows XP and Vista with drivers from the toshiba Web site.

    Any ideas on how to force this resolution?

    Thank you

    Hello

    Are you sure that the graphics card supports this high resolution!
    If all goes well it s not a material limitation

    But especially if the display resolution is not available the graphics card driver does not support this resolution of the screen.
    In this case only the new driver installation and usage help

    What graphics card is installed on your laptop? Graphic chip Intel?
    If you use an Intel graphics card, then I recommend to visit the Intel page and search for a compatible driver on this page. Some users here in the forum said that the Intel drivers could help choose the preferred resolution.

    In addition to the status bar you mentioned, there is another way...

    You have enabled in your Internet Explorer Menu bar?

    If Yes, click on view > text size options or select Zoom (100%). There, you can make the text larger / the screen as you wish.

    If you have no active Menu bar...

    Right-click on an empty space below the address bar > check the menu bar.

  • Cannot bar resolution move to set the screen resolution

    I just installed vista and everything was huge! I went screen resolution under Customize and there is no other options on the scroll bar expect I am the one on which is 640 X 480 at an average of 16-bit color, I tried to update the drivers for the card and the screen but its still the same, I also reinstalled vista but its still the same HELP!

    Go to the Web site of the manufacturer of your laptop computer-graphics/computer card > drivers and downloads Section > key in your model number > look for the latest Vista drivers > download/install them.

    If there is no graphics Vista drivers available for your model, nothing can be done about it.

    Then:

    http://Windows.Microsoft.com/en-AU/Windows-Vista/change-screen-resolution

    Change the screen resolution

    Screen resolution refers to the clarity of the text and images on your screen. At higher resolutions, items appear sharper. They appear also smaller, so more items adapted to the screen. At lower resolutions, fewer items adapted to the screen, but they are larger and easier to see. At very low resolutions, however, images may have serrated edges.

    See you soon.

  • When turned on my laptop, there is a black border around the screen.

    Original title: screen resolution problem

    Hello

    A few weeks ago, I turned on my laptopn and there was a black border around the screen. I managed to change the screen resolution, but my laptop seems to think that I have a dual monitor? And my resolution is still not like it was before. Obviously this isn't a huge problem, but it's annoying to have to go and change it regularly.

    In addition, given that this has started to happen, I noticed that when I turn on my laptopn, instead of the usual Acer / Windows startup screen, the screen is all black, until the login screen appears. I don't know if this is related or how, once again, this isn't a big deal in the grand scheme of things, but if an update is installed, you do not see the progress it's making!

    I ran a system restore, without success.

    Running Windows 7 on a laptop Acer Aspire. Any suggestions welcome, although I'm not that tech-savvy!

    Thank you

    Hello

    The first thing to check is your theme controls. Go to the control panel and select personalization. When this window opens, go down and select wallpaper. When this window opens go to the lower left corner and make sure that the background that position of the image is set to 'bridge '. Save the changes and return (right click on the name of the theme in the theme dialog box).

    Let me know if this solves the problem for you.

  • Lenovo blue G550 laptop - red, yellow, spots and lines on the screen

    Hello

    I have a laptop of Lenovo G550 old 2 year, system model 20023 (Dual-Core CPU T4300 2, 10 GHz, 3, 00 GB RAM) running 32 bit Win 7 Home Premium OS with graphics card Mobile Intel (r) 4 Series Express Chipset Family.

    Months ago, I started having 2 vertical lines on my screen, that change color and tend to disappear when I tilt it. Recently, the problem is a graduate in red, blue and yellow spots on the screen. Tilt is no longer works, but I noticed a report defined the degree of pressure on the case. When I pushed hard enough on the left below identify the cases (the hard drive where), the problem is completely solved. I also tried to connect another monitor and there seems to be no problem either. Help, please.

    Graphics card problem seemed highly unlikely with the image of the external monitor that appears to be normal. I tried reseating the LCD cable and it fixed the problem.

  • How to set the screen resolution to fit monitor

    original title: monitor

    I have a large screen, but it seems as if it was a waste of money because I don't get to use the middle of the screen. Can someone tell me please how to get full use out of my monitor? do I need some sort of version beta or something?

    Your description is not very clear, are the main steps to configure your display:

    -Make sure you have the latest drivers for your graphics card & monitor installed Windows 7 .

    -Search in the manual of your monitor and find out what the native resolution & refresh rate are for example (1920 x 1080 @ 60 Hz), then go to:

    Start-> Control Panel-> display

    and together that view you these settings.

    -If you have black borders around your screen, you should increase the size of your screen through the software installed normally with your graphics card. For a basic card ATI look for a feature called overscan/underscan. Look for the option to increase the size of the desktop in the nVidia Control Panel for nVidia cards. For othe graphics cards check support manual/website for advice.

  • How do I set the screen window size in a guest LinuxMint17 (WS7)?

    I am always on WorkStation 7 (last revision) because I discovered that after installing the update I bought I would be able to use 7 and I need that for some of my virtual machines...

    Anyway, now I need to test some features of Web server and need a KDE LinuxMint17 machine for this.

    Installation went well and I also installed the virtual machine; Tools of dishes without problem.

    As part of the installation, I put the size of the screen for the guest to 1024 x 768 in the properties of the VM.

    Then I could install the basic software that I need the terminal of the virtual machine.

    But it turns out that this screen is too small for the webbrowser, I need to run inside the guest, so I stopped and then replaced by the properties of the vm to display 1280 x 1024.

    The strange thing is that the guest does not adjust when I start again, it always appears in the size 1024 x 768.

    So I'm looking for help set the size of the screen correctly in the comments of LinuxMint17...

    Is it possible to make the largest screen in Linux?

    I looked at the System_Settings/Display_And_Monitor inside the guest, but I do not get a way to resize it.

    Or maybe there is way to allow resizing screen in VMWare Workstation settings for the prompt instead?

    Note that I have running in a window rather than the full screen because I use it as a test machine for stuff that happens in Windows...

    I tried Googling for Linux screen size settings but came empty-handed, suggestions addressed the other issues...

    I do not use Linux Mint but on other Linux Distros, I use the xrandr from a Terminal command to set the resolution of the screen when it is not available from the GUI.

    Execution of xrandr by itself will be out the available resolutions then, for example, use: xrandr-s 1024 x 768
