  • Why can't I adjust the brightness of the display on my M1330? (using Win7 & LED backlit)

    I have an M1330 with the Intel graphics card and the backlight. I am running Windows 7 RC1. I cannot adjust the brightness of the screen at all in Windows Seven - no matter if I use the FN + up / FN + down keys, the brightness slider bar option in Windows, or adjust it in the bios. The backlight is 100% brightness, or turned off completely.

    Does anyone know of a fix for this?

    They installed drivers for devices from Windows 7 for your make and model. If this is not the case, then go to the support web site factory and download Windows 7 drivers to a folder on your PC and then first install the drivers for the card mother/chipset, followed by USB, SATA, LAN, Audio and all other pilots.

  • 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?

  • Is it possible to adjust the brightness of my screen?

    Is it possible to adjust the brightness of my screen?  If so, how?

    If it's a desktop monitor, there should be buttons on the monitor to do this. I found this a useful tool, you can set a different brightness for the display of day and night. However, you can also just use it to quickly adjust the brightness at any time.

    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.

    Hello MarieJenkinson,

    1. do you have a good application software installed on your computer?

    I also suggest that you run the Audio troubleshooter. This will allow to diagnose and automatically fix the problems of noise and acoustic:

    If you have a sound software application to control the audio files on your computer. I suggest that you uninstall the software that she could be in conflict.

  • 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!

    Hello

    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.

  • Satellite L500 - cannot adjust the brightness of the screen

    I have a L500 - came out with Windows 7. I can't also adjust the brightness - the external monitor is fine. 17 other laptops in the same school are fine - just this one.
    The FN key doesn't seem to work - the laptop screen is so dark, that it is not readable.

    I didn't know all the answers that respond to that?

    Hi redmg,

    The FN keys are controlled by value added and Flash Cards Support utility package. So if you can use t FN keys correctly reinstall these two tools of Toshiba. You can download on the official page of Toshiba:
    http://EU.computers.Toshiba-Europe.com > support & downloads > download drivers

    But remove older versions before installing the new versions.

    After that all FN keys should work properly again.

  • Cannot adjust the brightness after installing Windows 10

    Hello. I have a Dell XPS 15 L521X.   Recently updated to Windows 10 and I can adjust is no longer my brightness upwards or downwards.

    Now the screen is quite low.  I'd say about 30-40% brightness.  10 widows I found about 5 different places to adjust your brightness and I made sure all of them have been set to 100%.  I have my power plan to high performance and I went into advanced settings and turned off Adaptive brightness and made sure that the brightness of the screen the two Dim brightness set to 100% on battery & are plugged.  Rebooted and still dim.

    My question is, on Dell laptops, Windows has full access to the brightness control?  Or Dell replaces Windows with their software customized for the display settings?   When I bought this laptop in 2012, the software, at the time, was called Dell QuickSet.  What is the responsible application of brightness of the screen control?  And is it necessary?

    Thank you

    Mike

    I am also having this same problem. My brightness has been set at max after update and it hurts my eyes. I did it... Control Panel > Device Manager > graphics cards > Intel HD Graphics 4000 > pilot > Update Driver > Browse my computer > let me pick. Choose Microsoft Basic graphics card.

    After doing this, my problem was solved, and I was able to adjust the brightness of my screen again. BUT if you play games on your laptop, it will cause display problems in your game.
