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?

Well, nevermind. Problem solved I guess. I did a restart instead of a shutdown, and it looks like it started working again. Not sure why it wasn't before.

Hi,My brightness control does not work. Fn buttons for brightness control don't work as well. I've tried all methods given on the internet such as updating the driver through device manager, changing the startup application etc. Quite frustrating that I cannot change the brightness settings.

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.

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.

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'm using Win7 64bit in Inspiron 3542.
   After i resume windows from hibernate, brightness control is not happening using quick keys. Every time i need to go to control panel & change manually. Other quick key functions are working except the brightness control.  The brightness bar stuck like below.

  Even killed quickset process & opened again, nothing useful in it. But when i reboot the system it starts working, and problem starts again when i hibernate.

A:brightness control not working after hibernate

I take it that when you notice this, restarting the notebook corrects the problem every time? I am not suggesting this as a solution(sometimes i would rather see the dentist than have to restart one of my PCs) but I want to make sure that this isn't a hardware issue. 
When you notice the problem with the brightness keys try holding down FN when pressing them and see if there is a change. 
As another test go into Windows and change the power plan and change it to "high performance" before hibernating the notebook. Before resuming plug in the AC adapter and see if you are now able to adjust the brightness, if you are able to then this becomes less of a problem with the function key behavior and an issue with power management.

A:Brightness Function Keys( f2 and f3) NOT Working

Hi, Well that does explain why your f2/f3 keys aren't working as you only have the basic Microsoft driver installed - if the Intel driver was previously installed Ok, this may indicate a hardware issue. What happens if you try to install the Intel HD 5500 driver directly from Intel - it's the 2nd file in the list on the following link. https://downloadcenter.intel.com/search?keyword=Intel%C2%AE+HD+Graphics+5500+for+5th+Generation+Intel%C2%AE+Core%E2%84%A2+Processors If this does install Ok, restart the notebook and let Windows fully load for a couple of minutes before checking. Regards, DP-K

I'm having this strange issue that I noticed a few hours back ... for some reason when i change power plan from the taskbar batter icon, the screen brightness doesn't change, no idea why/what could trigger this as I've not updated the nvidia driver for a while now, not sure I think 6month + or so .. and it was all working fine.
Also beadvised I haven't updated windows for a while ether ... so its probably not the fact that a win update caused this as I haven't updated for a while and last I check .. and once again about 6month or maybe 8months back .. it was working fine.
Also if i right click on the batter icon "adjust screen brightness > the vertical scrollbar" .. when i move it left or right ... nothing happens.

Strange thing is .. when I use the laptop on batter or there is power outage .. the screen brightness gets reduced as it should be.

This thing really isn't effecting daily usages however as its an issue, I would like to get it fixed if possible, any ideas?

System specs:

By accepting the solution when the issue is resolved, others will be able to find the steps that work also.   To help computers start faster, on some models the HP splash screen is not displayed during the start up process. In this case,you can try these steps to see if it is possible for you to enable the HP logo screen:Restart the computer.Press F10 repeatedly to enter the system BIOS screen.Select the Boot section using the right arrow key.Select Boot-time Diagnostic Screen using the up and down arrow keys.Press Enter to select boot-time diagnostic.Select Disabled to show the logo screen.Press Enter.Press F10, and then press Enter to save the changes and exit the system BIOSThis should enable the splash screen if it is available to be enabled.  If this reply helped, please use the Accept as Solution button.

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

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0001]
"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...
