L520 - can't adjust the brightness

Another problem on my Lenovo Thinkpad L520:

After you have installed the Lenovo power management driver, I can no longer adjust the brightness of the LCD screen using the keys FN + DELETE/POS1.

Immediately after setting the brightness, it gets returned to its old value, defined in the power management software.

I tried the Windows 7 (1.65.05.21) driver and the driver WIndows XP/7/8 (1.66.0.22), both with the same result.

It's really annoying and I'm very frustrated with Lenovo now, because is not the only problem I have with the phone.

I tried to call customer service, where an automated message directed me to their support forum.

Someone here has a solution for this?

Can confirm all these probs!

Brightness: uninstall Lenovo Hotkey Pack / Power Management Software (not Power Management driver)

For HARD drive: HDDScan using > select your HARD drive > build command line > your power settings. After you save your batch/cmd, start a plane of task!

    Hello:

    Yes that's fine.

    Here are the graphics drivers that you need for the W10...

    This package provides the graphics driver AMD/Intel switchable high definition (HD) for models of laptop computers that are running an operating system supported. For laptops equipped with switchable graphics modes, this package contains the drivers for the two graphics (GPU). Switchable graphics allow users to switch between a mode of graphics to save energy (normally used under the power of the battery) and a high-performance graphics mode.

    Help, please!

    I totally agree with kody;

    If you have XP OS, you must install the common modules first.
    It is very important that this driver would be installed before the other Toshiba Utilities.

    But generally it s necessary and indispensable to install all available Toshiba drivers and tools for you notebook series in the right order.
    I saw the Setup file instruction txt on the driver page.

    Please follow the order mentioned in this text file.

  • Qosmio G30-140 - cannot adjust the brightness of the screen on Windows 7

    Hello

    I installed Windows 7 on my Qosmio G30-140, but I can't adjust the brightness settings.
    Instead of allowing me to place the cursor on any position, I want that I'm stuck with only 3 steps which elect to.
    The last of them is way to bright and my eyes keep tear having to deal with this crazy amount of white, especially on white background.
    The other two are very, very dark.
    What is going on? I installed the right Nvidia drivers.
    Also, I can't adjust the brightness using the FN keys on my keyboard. They simply produce no result at all.

    Need help appreciated, I can't work like this.

    Thank you!

    Hello

    The brightness of the display can be controlled by the FN + F7 and Fn + F6.
    I think you should install the VAP and buttons of the Support of Flash memory card utility in order to get this to work!

    Check the added value Package and Support Flash Card which are released for Satellite L500 utility or new models of laptops.
    In my case it worked!

    You can adjust the brightness of the screen using Toshiba Power Saver? With this tool, I can set the brightness of the screen for Macintosh (AC adapter) and normal (battery). I like it a lot because I can also put more options and you can download it on the Toshiba site:

    For the FN keys on your laptop, you need the tools Toshiba you can find on the site of Toshiba, too.

  • X 1 yoga: cannot adjust the brightness

    I can't adjust the brightness on my Thinkpad X 1 of Yoga. I ran all the updates driver, lenovo used and everything is up-to-date, including the BIOS. No matter what I do the brightness will either increase or decrease.

    It is stuck on its maximum intensity, so is not too bad, and I would be reluctant to send in for repair and lose a week or work to get it fixed. Anyone can suggest that might help the wise software?

    Thank you!

    Moderator Note: added the object model for better visibility.

    In response to the customer reports that the brightness of the screen can be controlled via a key entry on X 1 Yoga ThinkPad, Lenovo has released a fix. The patch is a registry change to restore this function.

    The patch can be downloaded here: http://support.lenovo.com/us/en/downloads/ds118463

    A permanent fix will be delivered with the Intel driver in a future release.

  • I am not able to adjust the brightness of my screen, Lenovo P500

    I just upgraded my system to Windows 8.1. And I stuck with this sun screen. I couldn't change the brightness of the display using the keys. I also tried to adjust the brightness on the control panel power Plan, but nothing works.

    I had the same problem before too, so I used to roll back the driver Intel HD, and the problem used to be solved. But after the upgrade of the system, is there no option for Driver up. So, how can I adjust the brightness of my screen again?
