Brightness not working

Q: Brightness not working

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?

Preferred Solution: Brightness 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.)

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.

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 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.

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.

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 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.

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 ?
