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.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

Hi, I'd try reinstalling the amd/intel switchable graphics software package on the link below as it mentions a fix related to the f2/f3 keys. http://ftp.hp.com/pub/softpaq/sp74501-75000/sp74717.exe When this has completed, restart the notebook. Regards, DP-K

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.

Hello, My HP Probook 450 is with Windows 7 and the combination FN + F9/F10 is not working. The other FN keys seem to be in order, but I can't change the brightness of the desktop directly with the FN keys. Can you please help me fix this problem?

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.

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. However, I realise that after I click on 'Let me pick from a list of device drivers on my computer', it states that I have two of the same display adapters.  Thanks

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.

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.

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 ?

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.

Hi there,

Suddenly the Function F3 command to control the brightness has stopped working.

The Brightness can go down with Function F2 but F3 doesn't work

F3 Works in software and the Windows OS to pull up search, but not pulling up the control for brightness.

As such I'm stuck with my brightness down as low as it goes.

I've downloaded the latest Function key driver and installed, so it's not that.

Anyone got any help they can give?
