Preferred Solution: brightness functional key 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?

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.

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.

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.

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.

  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.

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?

Wndows 8.1 64bit

Hi,
 
I have the same problem: some of my function keys are not working.
 
My device is a HP zbook studio g3 with model number T7V83ES.
 
I did a clean install of 10 education since i could get that one for free and my previous version was enterprise. The keys worked on enterprise although I had some issues with it before only I forgot how to fix it. More people at my university that have the same laptop are experiencing the same problems, unfortunately this is not the case for everyone that owns the same laptop.
 
Here's what I did and what it resulted in:
 
-Installed every driver/program that seemed appropriate and was listed on the original  HP website for software and drivers for my device.
Result: My keys were not working at all. (brightness, project switch and mic mute keys)
 
-I asked google and tried every single solution I could find, including the ones you suggested.
Result: Mic mute key is working, project switch key is also working, and as if it was a miracle my brightness keys are also working! But: my brightness keys are stuttering like hell. It takes windows ages to register my keystroke and even longer to register another one directly following it; it can not register 2 keystrokes in a row, it needs a sort of cooling down time for the button.
 
This is a list of my installed drivers:
 
SP781133
SP70439

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
