I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

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.

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.

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.

A:BRIGHTNESS KEYS F2 AND F3 NOT WORKING

Hi: Did you install the Intel graphics driver from your notebook's support page? Not having the graphics driver installed is normally why the brightness is stuck on maximum, and why you can't adjust it lower or use the Fn keys to adjust it. Go to the device manager and click to expand the Display Adapters device manager category. There you should see an Intel HD graphics adapter listed there. If you see a Standard VGA Adapter listed there, that means the graphics driver is not installed and that is why the Fn brightness keys don't work.

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.

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.

The brightness keys on my laptop are not working. When I click on the F12 key, it shows on the bar that it's increasing, but my screen's brightness is actually not increasing/decreasing. I've tried several methods, but nothing seems to work. I tried uninstalling and re-installing my device adapter that didn't solve it. Some suggested enabling/disabling the Fn key; I normally don't use the Fn key to increase brightness so I couldn't try that option. Every key/action that controls brightness does not work.

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

The brightness hotkeys used to be functioning correctly. After updating the Hotkey Support driver from (pre-installed) version 6.2.20.8 Rev.A the secondary screen and brightness function keys stopped functioning. I reset the device to factory settings after running a hardware diagnostic on the keyboard using the built-in hardware diagnostic utility. The function keys worked again. I updated Windows 10 with the latest available updates. The keys still worked. I updated all the HP drivers (except the Hotkey Support application) to the latest version using the pre-installed HP SoftPaq program. The function keys still worked. I created a system restore point. I then updated the Hotkey application to the latest version after which the keys stopped functioning. I uninstalled the latest version and installed version 6.2.20.8 Rev.A again, but the function keys did not work. I ran a system restore to the system restore point I created earlier and the keys worked again. Apparently something is wrong with the installation of the Hotkey Support application, causing it to not work. I hope this issue can be routed to the appropriate team and that it will be investigated.
