Windows 7 Laptop Brightness Control Problem (Solved)

Laptop Brightness Control doesn’t work after upgrading to Windows 7 

I recently upgraded to Windows 7 Professional x64 on my laptop – a Dell Latitude D530.

Everything went well and all the hardware components were recognized by Windows 7. However the Fn+(page up/down) display brightness control would not work and in Control Panel –> Power Options the Screen Brightness Slider would not move.

This frustrating problem is being reported in many places.

I tried going to the Intel website and downloading the latest drivers, but no luck.

With a 32bit installation I had tried installing the Dell Latitude D530 Vista drivers, according to this advice so that the brightness control worked, but this made the system unstable. The same fix would not work for 64 bit Windows 7 as there were no 64 bit Vista drivers available from Dell.

Thanks to the solution given here the Intel GM965 Express Chipset drivers given below do work on my Dell Latitude D530 (Windows 7 64 bit) and restore the Fn+(page up/down) display brightness control functionality.

Alternative Solutions:

1. F.lux – Automatically Adjust Screen Brightness and Color to the Time of Day

Makes your computer screen softer on the eyes when working at night – this is a very popular alternative – good review here


Ever notice how people texting at night have that eerie blue glow?

Or wake up ready to write down the Next Great Idea, and get blinded by your computer screen?

During the day, computer screens look good—they’re designed to look like the sun. But, at 9PM, 10PM, or 3AM, you probably shouldn’t be looking at the sun.

Downolad F.lux

F.lux fixes this: it makes the color of your computer’s display adapt to the time of day, warm at night and like sunlight during the day.

It’s even possible that you’re staying up too late because of your computer. You could use f.lux because it makes you sleep better, or you could just use it just because it makes your computer look better.

f.lux makes your computer screen look like the room you’re in, all the time. When the sun sets, it makes your computer look like your indoor lights. In the morning, it makes things look like sunlight again.

Tell f.lux what kind of lighting you have, and where you live. Then forget about it. F.lux will do the rest, automatically.

2. Desktop Lighter

You could also try the Freeware stand-alone brightness control called Desktop Lighter
It runs unnoticed in the system tray, uses only 1.5mb RAM, launches with Windows and uses Ctrl+> and Ctrl+< keys to control the brightness rather than the Fn keys

This is not a “true” brightness control – it doesn’t cut the power consumption, but uses some software manipulation of the screen function to dim the screen. I used it for a while until I found the driver above, and it was useful if I wanted to read at night in bed without hurting my eyes or disturbing my partner – but it’s no substitute for the real thing!

    Thanks so much for posting this! I have been looking for a way to do this for months now, ever since I upgraded my Dell D530 from Vista Ultimate 32 bit edition to Windows 7 Ultimate 32 bit edition. It (Desktop Lighter) doesn’t seem to actually dim the backlight, so it probably won’t save as much of my battery life as would a real fix (ahem Dell and Microsoft!!!), but it certainly makes it much easier to read in dark settings by lowering the pixel brightness. A great find! Thanks again!!!

    Thank you this worked great, ive been trying to get that to work since i installed windows 7 months ago.

    That driver worked, I have my brightness control back 🙂

    PS don’t use that Desktop Lighter program, it uses a software mask to dim the screen and doesn’t reset it, even after uninstallation.

    I have a Dell XPS M1330 running Win7 64 bit.

    None of these links worked for me (not even let me install, they said “The computer doesn’t accomplish minimum requierements” or something.

    I just uninstalled QuickSet64 and voilá!

    The driver worked for me, thank you.

      I have no idea. I only know that it works on the Latitude D530 – it may work on other models also

    Thanks a lot for your help. The INTEL GM965 EXPRESS CHIPSET Video Drivers for W7 32bits solved the brightness issue. Great work!

    can it work on hp g62-b80ev, windows 7 64-bit?

    • Alan August 21, 2012 at 7:42 am #

      I have no idea, sorry. You could try it.

    Can’t seem to find a solution for my laptop. HP dv7 4020sd Pavilion. Install chipset drivers, installed videodrivers, installed special keys keyboard driver, enabled the Fn keys in BIOS. Nothing works so far.

    Anyone has an idea?

  16. Alan October 24, 2012 at 11:47 am #

    Hi Steve, unfortunately the chances of this working are getting less. Older hardware will not always work with Windows 7 and the manufacturers of older hardware don’t bother to update the drivers.

  17. Ravi December 1, 2012 at 12:29 pm #

    I have to install it then I’ll give my opinion.

    This worked great for me – i had already downloaded the latest Intel chipset drivers, and the ones mentioned in the first solution were essentially a downgrade to an earlier set of drivers, but worked!!

    After upgrading my D530 to Windows 7, i’ve spent hours trying to figure this problem out… so thank you, thank you very much indeed for your help!! 🙂

    • Alan January 5, 2013 at 11:30 pm #

      I know, crazy isn’t it? It’s essentially a downgrade, and yet it works…

      Incidentally – I’ve subsequently discovered that if you upgrade to Windows 8. the brightness control for the D530 will work with the drivers included in Windows 8 – no need for the Intel drivers.

    hi, just upgraded old dell 1501 to windows 7 everything working fine except brightness , when I slide to increase its goes about threequarters then starts to dim screen. when slider is fully to the right screen has only about half brightness. when I slide it back to left it brightens up to about three quarters brightness then starts to dim as it should. in short it will not go to max brightness and always looks dim.its windows 7 ultimate 64bit please advise if these drivers will solve this problem or is it a duff screen

    • Alan November 2, 2013 at 10:17 pm #

      If it worked OK before upgrading then it is probably not the screen. So it is probably the driver you are using with Windows 7.

      If your 1501 has the INTEL GM965 EXPRESS CHIPSET you could try installing the Dell drivers given above, or look for Vista drivers for the 1501 on the Dell website
