Preferred Solution: Brightness is not working

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

For some strange reason, the brightness doesn't appear to be increasing or decreasing anymore. Whether I try it from the FN key function, or the power options and even under settings on the right swipe menu, the brightness on the monitor is not changing. I trying rebooting, but that didn't help either. I'm runing an acer aspire ES1-512-C1W0 with Windows 8.1 64bit 4GB RAM. Any ideas what's wrong?

I buyed hp laptop. It came with DOS but i changed it to windows 8. But the brightness keys were not working. But all others keys were working properly.

A:brightness keys are not working

HP does not post Windows 8 drivers for that laptop just 7 and 10. Check device manager and see what is showing for display adapter. If it is Microsoft Basic brightness adjustment will not work. I suspect you need quite a few drivers for it which we are going to have to help you get from hardware manufacturer sites.  Post back with identity of display adapter.

If you are looking for some assistance, you will need to identify your notebook with its complete product number. Otherwise, we really can't help you. When logged into Windows.

A:Probook 450 fn + brightness not working

Did you just install Windows 7 on it or had the brightness key been working and just stopped? The brightness adjustment depends on the video driver and also on the Hotkey Support driver here: http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdHome/?sp4ts.oid=5359407&spf_p.tpst=swdMain&spf_p.prp_swdMain=wsrp-navigationalState%3DswEnvOID%253D4058%257CswLang%253D%257Caction%253DlistDriver&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken So I would reinstall the Intel chipset driver, the video (AMD or Intel) and the Hotkey driver and see if it clears up the problem. If this is "the Answer" please click "Accept as Solution" to help others find it.

I seen all the past replies on fixing this problem. One even said HP enables the keys f1-f12 eventually. Even so, I brought this notebook just last Christmas '15.  Here's the rub,  Microsoft installed some updates recently, since then the f2 & f3 for bbrightness are the only f-keys enabled. Not all users are young, these keys are a must for seniors who are on computers and eyes aren't what they use to be. I even downloaded the driver again for this and still not workng. Should I take it back to store? Still under warrenty.

I have a Dell Inspiron 5555 that I purchased today from the Microsoft Store.  The computer works great, but I've noticed that when I try to change the brightness using the brightness keys (F11 and F12) to adjust the brightness, they don't work.  I did get it to brighten up the screen once, but after doing that, I have been unable to make any changes.  Has anyone seen this and does anyone know something I can do or try to see if I can make these keys work?

A:Brightness Keys not working

The F keys toggle between Media and normal functions by using the FN key. Try using the FN key with the brightness F key--which is not necessarily F11 or F12. Check your manual. The sun symbols on the Function keys might tell you where the brightness settings are. On my model it is F3 & 4.

You can reverse the toggle settings to make the function you use most the default. The default doesn't use the FN key.

Welcome to Seven Forums Nurein615. I think you can adjust it in BIOS with the down right keys (I hope they work!). Here is a (poorly made ) video that will illustrate how. Basically, F2 at boot, then video settings, then brightness. Don't go too bright as you have no left key to turn it back down! Good luck!

Hey guys, so I upgraded to Windows 10 which caused the computer to automatically update my drivers and what not on July 29th, and here I am with a brightness adjustment that does not work whatsoever. Pretty much, whenever I press the less/more brightness buttons on my keyboard, the display will show the brightness gauge going up/down but the actual screen brightness remains constant. Yet, when I roll back the driver it manages to allow my brightness adjustment to function again, but my second monitor will not connect even though it is plugged in via HDMI. Obviously attempting to get my old Windows 8 driver will do me no good since this laptop is no longer a Windows 8. I'm pretty stumped here, especially since I'm not the best with the complex side of computers, I'd just like my brightness adjustment to work again while maintaining/keeping everything else Thank you in advance for your help

I shut down my laptops once every week; they're either in sleep mode or hybernating. My P50 is currenly running Windows 7 Pro with all the drivers installed. I have changed bios settings such that the function keys behave as function keys and only act as media keys (or whatever they're called) when pressed in combination with the Fn key. All hotkeys work as they are intended to.However, resuming from hybernation causes only the reduce brightness key (Fn + F5) to stop performing although all other hotkeys work as they should. Pressing the F5 key by itself works normally; its just the Fn + F5 combination that doesn't work.Anyone experiencing this ?

Hi. Thanks for any suggestion or advice you can provide.
I have been using Windows 7 on M6600 for a while. it mostly worked besides I was getting "Nvidia Kernel Mode Driver has stopped responding and has recovered issue" at times and I had no choice but to reboot to make it work again, that is for a while...
When windows 8.1 became available via corporate, I got hold of it and decided to reinstall fresh. 
I saved all my data and wiped out windows and recovery partitions, leaving dell system partition.
Windows 8.1 install was amazingly fast, 15 mins. As soon as I booted I installed Dell chipset driver, video drivers and other drivers. All device manager entries were with no warnings, some drivers were found and some I installed from Dell site. I installed most critical programs and all was cool and working. Nvidia video driver crash seems to be gone too. I have 2 other windows 8 machines so my windows 8 experience was there and I am quite happy with everything in windows 8.1
Then eventually I noticed that LCD brightness does not work. I made sure I had Dell Intell HD 3000 driver, Dell Nvidia driver and Dell feature pack installed. I tried with Dell feature pack and without it.
I researched this topic, found some other reference to Windows 8 having the same issue. I do have 3 monitors and do run Optimus. this all worked very well in windows 7.
Some posts suggested that it is critical to install drivers in order. I started doubting my install proce... Read more

A:fn+brightness not working on windows 8.1 on M6600

SOLVED. By installing latest HD3000 driver from Intel, then create a HD3000Fix.Reg file with these entries, open file or apply in Windows RegEdit (be careful as usual), then reboot:
----------------------------------
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000]
"FeatureTestControl"=dword:0000ffff

"FeatureTestControl"=dword:0000ffff

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\intelkmd]
"FeatureTestControl"=dword:0000ffff
----------------------------------
I've been using this for two years for each time Intel updates the HD3000 drivers and it works well for Windows 8.0 and Windows 8.1 on two different PCs including Precision 6600 with Intel HD3000 video.

Hope this helps others...
