Win8.1 brightness change not working

Q: Win8.1 brightness change not working

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?

System specs:
--------------
Asus X555LF
Wndows 8.1 64bit
Intel? Core? i3 5010U Processor
DDR3L 1600 MHz 8GB SDRAM
NVIDIA? GeForce? 930M with 2GB DDR3 VRAM

Thanks in advance.

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.)

Also on another note probably the graphics drivers are working fine or atleast the nvidia one is .. as I can games like blade and soul etc just fine .. no visual issues or anything. Could it be that the intel driver or some other ms driver related to the display adapter got damaged somehow maybe

I received an acer Aspire r13 as a school laptop. For some reason I am not able to change the screen brightness. The icon appears like this I have tried using function+arrow keys but nothing works. I have turned off adaptive brightness but still nothing. my laptop is stuck at a very bright level, rendering it unusable during the evening/night. Any help will be much appreciated

A:Cannot change brightness on 8.1

Have you checked for newer graphics drivers or graphics control settings program? If you try different drivers and System Restore works on your PC, make a Restore Point before changing the driver so you can get back to square one if things end up being worse.

Another thing you could try is checking out all the settings in the power profiles. Sometimes there is a brightness setting that may override the main setting.

If all else fails there's the old Jedi Support Trick. Boot into Safe Mode and go into Device Manager. Delete or uninstall the offending device and reboot. Windows will say "new hardware found" and install the driver that you deleted. For some weird reason this seems to fix many device issues in Windows. It works quite often and is very low risk.

I have a Compaq CQ58 laptop that I got a few years ago. I just installed Windows 7 Home Premium on it, and I have installed all of the necessary drivers off of HP's website. However, I can't seem to change the brightness. I tried holding Fn and pressing F2 and F3 to change the brightness. I clicked the battery icon on the system tray, but there was no brightness slider. I tried going to the Power Options, but still, no brightness adjustment. I'm not sure if there are some drivers that I don't have installed, or Windows 7 cannot detect that the brightness of my display can be changed. My brightness is just stuck at full brightness, and looking at the screen in the dark without being able to dim the screen eventually hurts my eyes. Thanks in advance to anyone who can solve my problem.

Hey, Guys.

I just yesterday finished my new computer (16Gb RAM, i5-4470k, GTX 770, Win 8.1, etc.) and I just today realized that I cannot change the screen brightness. The button is grayed out and says "Unavailable" which I know cannot be possible.

Now, i have done my research and people say that the fix is to update your drivers through the Device Manager, and I have tried that to no avail. I have tried all possible combinations of "Display Adapters" and "Monitors" drivers. None work. I have been restarting my computer after every change and I have no idea what there is left to do.

One thing that I might add is that a lot of people remedy this problem by reverting their Intel Integrated drives back to an older version, but I do not have an option to change it's drivers. It shows up nowhere in the Device manager.

My eyes are burning as I am typing this and I would even go for a third-party brightness program (if that even exists).

Thanks in Advance,
Cam

Screen Brightness - Adjust in Windows 8

RELEVANCY SCORE 49.6

I have an Acer Aspire 8930G with Windows 8.1 x64 and Windows 7 x86 as a dual-boot. I use 8.1 as my everyday OS and only boot into 7 to play older games that only work with a 32-bit OS.

Ever since I installed Windows 8, I have not been able to adjust the brightness of my screen. Note that this problem started since I installed 8, not 8.1, and before I put on the copy of 7 as a dual-boot. When I use Fn+left/right (the brightness keys on my PC), the brightness slider appears on-screen and goes up and down, but the brightness of the panel doesn't actually change. Using the Charm doesn't help either, nor does adjusting it through the Control Panel.

I have tried fiddling with my Power Options in the Control Panel and disabling adaptive brightness. I have tried several different driver versions for my GPU, a GeForce 9600M GT. None of this has helped.

In Windows 7, however, the brightness controls work fine. If I want to adjust my brightness for 8.1, I have to boot into 7, change the brightness there, and then boot back into 8.1, where it will keep whatever brightness setting I was using in 7.

Does anyone have any ideas on how to fix this? Is there some messed-up thing in the Registry? Is my GPU's firmware maybe just not compatible with Windows 8? I took a look at TechPowerUp's repository of GPU BIOSes, but it appears I already have the most recent one.

Hi I was wondering if there was a way to bind a key to increase/decrease brightness of my laptop screen.

I can use the regular FN+Fnkey combo but I am using an external USB keyboard so it would be easier to use a non FN key combo.
I tried reading the scan codes of the FN+F6 key but I couldn't get any, so I can't remap it with a tool like AutoHotkey.

Also, since I have the slider thing in Control Panel > Power Options, this seems doable with a software.

Last note. I do not want a 'screen dimmer' program that does not actually dim the LEDs behind the screen.

Thanks for your input!

I am still getting used to Win 10 on a tablet and one annoyance (system design flaw) that I would like to change is the 25% increment screen brightness in the action centre button (swipe left). 0% is way too dim and 25% is too bright in a dark room. I know I can control screen brightness better through desktop settings but that is far from convenient on a tablet. Has anybody found a hack to change the increments to say 10%? I searched the registry for "brightness" and came up with a couple possible entries (one below). But then it also kind of looked like the increment may be controlled by the dll?

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power\PowerSettings\7516b95f-f776-4464-8c53-06167f40cc99\aded5e82-b909-4619-9949-f5d71dac0bcb

You must hold the FN key down and press one of the F keys (top row) at the same time, I think it's F9 and F10 to change the brightness on HP laptops, there will probably be a 'sun' symbol on the key with up or down arrows.

I purchased my Dell Inspiron 15 3537 laptop a year ago and up until recently it had worked fine, however recent problems i have encountered have been as follows:
-If i close the lid or use any other method to try to put the laptop into sleep mode the screen will turn off, as normal, but it cannot be woken by any means, requiring a forced shutdown then restart.
-If the laptop is left to idle to long and the screen turns off, but not to sleep, the same situation as above occurs.
-Sometimes, but not every time, when the laptop is restarted it doesn't recognize any AMD graphics driver, or any AMD device which i assume means it cannot detect the card
-Sometimes, but not every time and seemingly not linked to the AMD problems, when the laptop is restarted I am unable to adjust the brightness of the screen by any means, the keyboard buttons do not work and the options usually found in the power options are no longer visible.

I've bought a laptop that I've had for more than 4 months now, and within the last week have been unable to change the brightness of the screen (from the control panel or the FN keys). I've scoured the internet for an answer (and solution), but I've had no luck.

It's not the upgrade to 8.1 that did it because it worked until last week (8.1 was probably on my laptop). I've tried changing the display driver, which to some extent works (when the driver is changed, the brightness will change to the control panel setting). I want a better solution to doing that each time (I change my brightness often enough for that to be a problem). I've also tried rolling the driver back which did nothing.

Obviously there is no doubt that the n150+ or any Samsung note/netbook have had problems with not being able to control their devices brightness on Windows 7. This is because any driver after the OEM driver would change a particular number in the registry(regedit)

There were two fixes to this problem in WIndows 7. The simple way was to install the original VGA driver. The other was to change a specific number to 84 in the registries.

I have tried both and still can't adjust brightness with the fn keys. I've installed Easy Display Manager which is the software required to use fn key functions. Sound works automatically with or without the software.

I'm wondering why I can't get this to work.

I have tried with the cable out and in the PC. Nothing has worked. Any help on this is appreciated as the screen being so bright all the time is off putting.

Hi,You can install graphics driver from your HP support page compatible with Windows 10, restart system and check if issue is resolved.Usually this would do the trick.Hotkey support driver may also be installed afterwards is issue persistsRegardsVisruth

Id like to first start off by saying I apologize if this is in the wrong thread. I know a bit about computers but not a lot so I wasnt sure what thread would be best for a brightness problem.

Secondly, I know my laptop is old. I'd love to get a new one but thats not an option.

So essentially ive been this having this problem for a good long while. It just randomly acts up and then fixes when I restart my computer. I wont be able to change my brightness AT ALL.
FN keys dont work. The brightness slider (does show up) doesnt work, and trying to change from high performace to balanced doesnt work either (and yes the sliders are different in the 2 settings).

Ive looked everywhere for a solution to this problem and just cant find a thing. Either people have a different brightness problem or a different solution which doesnt work for me.

So any help would be greatly apperciated. Im hoping that since Ive come across so many other brightness problems on my search maybe someone will be able to help me with mine.
Thank you.
