Lenovo touch, Z400 problems of brightness in Windows 10

I just upgraded my Windows 10 laptop and when I started the brightness on my screen was very low. I tried to adjust the brightess I normally would (Fn + F11 (or F12)), but it does not change even if the brightness it recongnizes me wanted to change.

I had this problem during the upgrade to Windows 8.1, but the fix I had to do this does not work on Windows 10. Any help?

  • TouchSmart IQ506 touch screen problem

    Our company has recently obtained a TouchSmart IQ506 with Windows Vista 64 bit and everything works fine. We did a cool, been reformatting in the network and ran all the updates and others. As you may, or may not, know, the IQ506 isn't a VGA port to install a second monitor or to connect to a projector, so that to use the TouchSmart mirroring an image to the projector, we bought 2.0 of StarTech USB to VGA Display Adapter. I installed the drivers and got work and mirroring the image properly, however, now I'm having a problem with the touch screen.

    The touch screen responds when I touch it, but that the pointer is emptied all the way to the right. Mouse follows my pen up and down with me, but it does not come to the left. It's as if the screen is only read the coordinates there where I touch, and coordinates x are blocked all the way to the right.

    The touchscreen was working perfectly fine until I installed the graphics card driver and software for the VGA display adapter to work. The keyboard and the mouse works fine, everything is perfect except for this touch screen problem. I'm 99% sure it's a software problem, and I wanted to know if there is a known issue, or if anyone else has had this kind of problem. I guess this is the software for the VGA graphics card and I was wondering if this is the case, what I can do for the TouchSmart can support a second screen bypassing screen touch, or any other, problems of alternatives.

    Sorry in advance if there is already a topic on this issue, I went thorugh the forums and can't find anything about it.

    RasterBlaster thanks for your comment.

    I wanted to try something before your steps and I seemed to have solved the problem.

    The problem is that the nvidia card driver was not cooperating with startech to the VGA graphic card driver. I uninstalled the nvidia card driver and all this work and am now able to see on both screens.

    I know I'm going to miss some qualities of video, but from now on, everything works and I think it's what is best. I will try to reinstall the graphics driver, but right now, the problem is resolved. Thank you.

  • Problems with brightness adjustment

    Hello!

    I recently bought a new laptop with Windows 8 Pro. It's a Sony Vaio S Series, aged only two days.

    My eyes are very sensitive to light, so I kept the brightness on my old laptop less over time, but it won't let me change the brightness settings.

    I tried to change it on the charms of the bar, as well as the settings of the power plan and the Fn keys, but every time that I change it, it immediately self-aggrandizing ' adjusts to full intensity. I tried searching through the peak power plan settings, but cannot find the setting to turn off the automatic setting.

    He will show me he peut change brightness, but that he will not remain at the level I want for more than half a second.

    Any help would be greatly appreciated!

    Hi, Annie

    It seems that everyone wants to control the brightness on your computer, Windows, Sony, hardware, etc.

    Here are links to some tutorials with more information on how to do this.

    Adaptive brightness - turn on or off in Windows 8:
    http://www.eightforums.com/tutorials/6042-Adaptive-brightness-turn-off-Windows-8-a.html

    If you have this installed, it has a brightness adjustment of the automatic screen in the Vaio control center, look in the section view .

    Open Control Panel and select Power Options. On the left side, at the bottom of the screen, click the Windows Mobility Center .

    If none of these help, I would recommend that ask you this question on the Sony Support Forums. Someone may have found the magic options to solve this problem on your model.

    Hello

    > Original driver here on the TOSHIBA page... is too old... and mae AMD driver problem...

    I put t know how help you buddy the point is that the graphics card driver that is available on the page of the Toshiba driver is modified for mobile use and its recommended by Toshiba.
    Usually, you use this driver to make sure that the correct feature for laptop.

    Of course, you can try to use the other graphics card drivers, but in some cases, different version could lead to small different questions: in this case > problem with brightness control.

    However, you can try to install the graphics driver AMD/ATI driver Toshiba UE page but check the driver released for other series of laptop. You might get a more recent version of the driver.

    Brightness last but not the least similar problems could be value added Package update (for Win 7), but also the BIOS update (if available)

    I opened a new window in the main window of Firefox. The new window is nothing like on the main window of Firefox 4 Beta. And when I have tabs in a new window, the URL doesn't change. Infact, it changes nothing in the tabs. It remains that if I change it manually.
