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?

Hi: Did you install the chipset and graphics drivers?  That would be the only suggestion I can offer...Install and restart the PC. This package contains the Intel Chipset Installation Utility and Driver for supported notebook models and operating systems. This utility enables the operating system to show the correct name for the installed Intel hardware in the Microsoft Windows Device Manager. http://ftp.hp.com/pub/softpaq/sp52501-53000/sp52791.exe This package provides the driver that enables the Intel High-Definition (HD) Graphics in supported notebook models that are running a supported operating system. If high-definition multimedia interface (HDMI) video output is supported, this package also installs the HDMI Audio Driver. http://ftp.hp.com/pub/softpaq/sp61001-61500/sp61152.exe

A:(fn+F2 and fn+F3) for brightness are not working

What is the product number? Did anything change before this started happening? Power the system on and press F10 about once a second to get into BIOS.  Once you are in BIOS, go to the configuration tab (typically next to last tab) and set Action Keys to enabled.  Save the changes, exit, and the system should reboot automatically.  Test the brightness keys wihtout pressing the Fn key.  I suspect they will not work in this state, but I want to rule out the possibilities while awaiting the product number.

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.

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.

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

Good morning, I am lucky enough to have a shiny new ZBook 15u G3 which has a clean W10 install.  Lovely machine but I am expriencing some niggles with the hotkeys, specifically brightness (f5,f6) and I am not sure whether mic mute is working either (f10).  Keyboard backlights are fine (f3) as is volume (f8,f9). I ran the HP SoftPaq download manager to find all the specific drivers for this machine and while the HP Hotkey Support software seemed to be included in the bundle, it did not install. I have tried downloading and installing it separately but  keep getting this error message:  The file does exist, and I have tried running it directly from the 'Progam Data' folder but get the same error.  Finally I tried copying the msi file directly to the desktop which seemed to let it install i.e. it is listed in 'Programs and Features' but the functionality is still missing. I have also tried updating to the latest bios. I can change the brightness in the display settings and can increment in 25% steps in the action centre but it is not the same as just being able to tap a button.  This was an expensive machine and I am somewhat frustrated that this basic functionality that I require regularly is absent. Our IT guys are currently out of ideas, so any help or suggestions will be much appreciated.

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
SP76159
SP75561
SP56876

A:Up key not working, Brightness stuck on low settings (FN+UP)

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!
