First, techincal specs.
I have a Windows 8.1 Toshiba Satellite L875D-S7332, with a AMD A6-4400M APU processor with integrated graphics. My display adapter, according to device manager, is a AMD Radeon HD 7520G.

Now, my problem is that I'm unable to adjust the screen brightness of my laptop. I haven't made any recent changes, and I noticed this about a week or so ago(I don't typically change my laptop brightness, so this could have been happening for longer). In the mean time, I've tried rolling back my display drivers, with no success, and also updating to the latest driver set, which has also not worked. I'm not sure where to go from now, does anyone have any ideas to fix this?

A:Unable to adjust laptop screen brightness

Welcome to the Forums.
What happens when you try to adjust the brightness? Is there no setting? Setting grayed out? Or you change the setting but nothing happens?

If it changes for an instant, then reverts to what it was, adaptive brightness may be enabled.

In the past few days my laptop has been behaving oddly. At first it would not allow me to adjust the brightness, neither with the function keys nor the slider. This would happen after it awakened from sleep.
It also does not like to restart now. It hangs at the "Restarting" screen until I force it to turn off by holding the power button.
In, addition, the keyboard stopped functioning. This has only happened once, though.
I ran system file check from the command line. It found corrupted files, but was unable to fix them. I ran it again in "Safe Mode" and got the same results.
I tried rolling back the display adapter. This did not solve the problem either. 
Any help will be greatly appreciated.

I am having this problem from past 3-4 days I am unable to adjust my laptop's brightness. The functions keys for brightness won't work. I also tried changing the power settings to high performance and balanced, that also doesn't changes the brightness.
I also tried manually adjusting the screen brightness. The slider moves but the brightness is not changing.

I am using IntelR (HD) Graphics family.
I tried changing it back to Microsoft basic display adapter but that also didn't help.

I got windows 8.1 installed from the factory itself and everything was working fine until past few days.

Any suggestions??

P.S. => I am using a Lenovo G50 series laptop

A:Unable to adjust brightness in my windows 8.1

First off, figure out whether or not your laptop has an ALS (Ambient Light Sensor) which will automatically adjust the brightness (if all goes well). Usually it won't override a manual setting, but it's kind of up to the developer which one takes precedence. As for the keys not working, you probably removed (or didn't install after a Windows reinstall) the helper software that controls these functions.

Just today, my laptop won't let me adjust the brightness, and has completely removed the option to. I am currently running on Windows 10 (64-bit) and again, just today out of nowhere does not let me adjust the brightness. The laptop battery is completely dead (it doesn't work without being plugged in) but this issue has never affected anything. I would really appreciate some help with this ASAP as the screen is damaged enough already. Thanks  UPDATE: The laptop has now completely gotten rid of the option to sleep.

I've noticed, today, that I'm suddenly unable to adjust my screen brightness. I have read half a dozen threads reporting the same problem; I tried all the solutions therein (from updating the driver and reverting to the most basic one to manually changing power configurations) and nothing worked. Unlike the vast majority of users who had this problem, this hasn't happened following an update to windows 8.1 (which I did several months ago -- and the adjust was working fine after that).

This might give you a hint:

* As I try to adjust it using the fn key (as I had always done previously), brightness goes up or down just one level -- and that just 'cosmetically', as in fact nothing changes. The indicator gets stuck approximately in the middle of the bar, unable to reach the extremes.

* There is more: on power management, I chose the lowest possible level of brightness when working on battery, just to see what would happen. I then disconnected my laptop from main power, and... the brightness indicator did go down to the lowest level, YET brightness remained unaltered in fact.

Anyone, please??

Hi

I have had an Asus laptop with windows 8.1 for almost two years. Two days ago, I found that I can no longer adjust the brightness. When I use F5/F6 the brightness bar goes up and down between two levels but the screen brightness isn't changing. This has happened before but fixed itself within a day. This doesn't seem to be happening this time. I have checked some solutions to this problem but most people seem to have this problem after an update or upgrade to windows 8.1. This is the same operating system I have been using for two years and, as far as I can tell, there has been no update in the last week. I've checked the drivers and there doesn't seem to have been a recent update.

hi nikunjpadhiar,
 
Welcome to the Forums.
 
When you installed the (Beema) AMD Driver, did you remove any previous traces of the AMD Display driver?
 
If not, can you try the following:
1. Navigate to the Control Panel (Icon Views) > Programs and Features and uninstall anything that relates to AMD Display Driver / AMD Control Center.and reboot. When finished, navigate to the Device Manager > Display Adapters and the driver should show a Microsoft Basic Display Adapter.
 
2. Install the (Beema) AMD Driver (VGA, HDAudio, SATA) for Windows 8.1 (64-bit) and reboot. When done, the Microsoft Basic Display Adapter from the Device Manager should now change to an AMD Radeon Display and check if you can now adjust the brgithness.
 
In addition, check this post by marcus34 as he was able to resolve the issue.

The know the story. I installed a 120GB Samsung SSD into it, installed Windows 8.1 and it auto-activated as this Laptop came with Windows 8.1 so I didn't require another serial. It works fine, it's so quick (was previously unbelievably slow). However, the brightness won't adjust. I assume this is because it requires a driver.

The function (FN) + F4, F5 (the keys to adjust the brightness settings) do nothing. The brightness status will show up on the screen and only change 1 or 2 notches.

I then realized I should have a way to adjust the brightness via the Power Settings in the Control Panel. I even confirmed this with a friend. I should have the sliders to adjust the brightness but I do not. It's very strange.

Hello,

I've installed Windows 7 on my Qosmio G30-140 but I'm having trouble adjusting the brightness settings.
Instead of allowing me to set the slider to any position I want I'm stuck with only 3 steps from which to choose from.
The last one is way to bright and my eyes keep tearing up from having to deal with this insane amount of white, especially on white backgrounds.
The other two are very, very dark.
What's going on? I've installed the correct Nvidia drivers.
Also I can't seem to set the brightness by using the FN keys on my keyboard. They simply produce no result at all.

Hi there. I've installed a clean version of Windows 10 Home 64 bit, and, noticed that, with the basic Microsoft display adapter driver, I would be able to adjust screen brightness and would get maximum resolution as well. How ever, even though I disabled automatic driver updating in Windows before I first connected my laptop to the internet, it still proceeded to download a driver that it got via Windows update which ruins the adjusting of brightness. I tried to install the 64-bit Windows 8 driver that is available at support.lenovo.com but that one has the same problem, I can't adjust screen brightness when using it. Neither did the latest Windows 10 Radeon HD 6xxxM driver by AMD off of their website help at all. Everything else works perfectly fine in terms of Windows 10 except for adjusting of brightness, and, I am unable to stop Windows from constantly updating the graphics card driver via Windows Update despite the setting found in System Properties. As such, the laptop is, largely useless, and, has wasted loads of my time. It's a shame really, as, I invested loads into this laptop, and, though it's perfectly capable of running Windows 10, the fact that I can't adjust screen brightness wrecks everything. I have even installed the Energy Management driver, but, that doesn't help anything either. Could someone, please, advise me of some way through which I could make Windows simply STAY at the Basic Microsoft Display Adapter driver, or, w...

Thank you forum! Much gratitude here for your selfless service!!

I am not very tech savvy but I am usually able to solve my own problems. My cat jumped on my keyboard, my display went dim and I could not adjust it ! I am able to move the brightness bar up and down but nothing happens. First, I tried a system restore but that did not work. I went back about a month which was the earliest restore point I had. Then I went to device driver and looked to see if my driver was functioning properly. I was told it was updated and functioning properly. I tried clicking on the windows generic monitor driver also as advised which did nothing. I went to the device driver on the pc and updated from that which also did not work. I am using windows 10.

A:Cannot adjust brightness windows 10 Lenovo IdeaPC

Two of the keys on the keyboard are used to adjust the brightness; but, if they are printed in the second color, you may need to hold down the Fn key for them to function. If you can't find them (they look like little suns), I need the model number of the Lenovo to help you more.

A:brightness keys not working ; can't adjust brightness at all

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

I recently upgraded to Windows 8.1 on my Lenovo Ideapad and noticed my screen brightness wasn't as bright as it had been when I had run Windows 8. I keep trying to adjust my screen brightness, but no matter how low or high I set it, my screen's brightness
remains at what I would imagine a 50% brightness would be. Can anyone help me?

A:i upgraded to windows 8.1 and can no longer adjust my screen brightness

Ive tried all the suggestions above and more this is the only thing that has worked so far!
Try this....
Go to device manager - click display adapters - right click the windows driver (intel graphics 4000 or whatever) - update driver software - click search for update myself - then on the next window click "let me pick from a list of drivers on my computer
- then select microsoft basic display adapter


Edit..... come on microsoft this shouldnt be this hard computers should be getting more user friendly not less sort your s*** out!!

Hello all, Im not the best when it comes to knowledge of computers and what not but I'm completely stumped and so is everyone else on the web, it seems. Cant find a solution to this for nothing. I also did a search here on screen brightness problems and didnt find anything specific to my problem..

Basically I just installed Windows home 7 ultimate on my HP dv5t after previously having vista on it and I cant find how to adjust the screen brightness. I've googled it and others have had the same problems but I cant find how to fix it. My fn shortcut doesnt work, and when I go to power options and all that, theres no slider or even option to adjust brightness. Ive seen where it's supposed to be on windows 7 via youtube videos but it's not there. Anyone know what to do, or has anyone heard of this??

The only thing I've found is a thread here, post 14, where they claim a guy found a solution but It doesnt work for me, or maybe Im doing it wrong but ive done it several times.

Any help would be appreciated! I cant stand it anymore, I feel like im about to go blind..

i just installed Windows 7 Enterprise x64bit today
and i can not adjust the screen brightness
-before i installed the driver pack, it didnt even show this option
http://www.sevenforums.com/attachmen...1&d=1402424820

and after i installed the driver packs the option is there but its useless
i have put the screen brightness on minimum but the brightness is still maximum and my eyes are about to pop right now

somehow i don't have this problem on the x32bit version.

is there any driver that i have to install or any way to fix this ?

What driver pack? Win7 is a driver-complete OS after you enable Automatically deliver drivers via Windows Update (Step 3) then run all rounds of Impotant and Optional Windows Updates until no more are offered when doing a Check for Updates after reboot.

Any drivers then missing should be imported from the HP Support Downloads webpage for your exact model.

If you have an HP then don't reimport any of the HP bloatware but sometimes a piece of software is required to make the hotkeys function correctly. You'll need to study the software posted for your model to see which is required. If you tell us the exact model and link us to the webpage we can often spot it for you if you need help.

Hopefully you followed the other steps for a perfect Clean Reinstall - Factory OEM Windows 7 because you will get and keep a perfect install to the exact extent you stick with the tools and methods given.

If you forced a bunch of old drivers into an OS which provides its own drivers then you will have problems.
