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 @KokoKid.
It sounds like it could be a problem with a driver update. Did you perform a Windows update recently?
I did a search I found this: Solved Laptop screen brightness won't adjust

I hope this can help.

I have a HP Notebook 15 running on Windows 10. The Processor is Intel Celeron N2840. I recently Refreshed my Laptop To get rid of some useless softwares. After this refresh, Im not able to Adjust the screen Brightness through Display settings (the Option to adjust the Brightness is unavailable) or Keyboard (F2,F3) and the button in the Action Center to adjust brightness is also not available which I used to have Before. Also I updated my Intel Graphics Driver as directed in many Websites and also the Monitor Driver. But all these methods are not fixing my trouble. Further more, The "fn" key in keyboard is also not functioning, so im kinda' screwed with all these trouble.  It would be very helpful if anyone can mention any fix, Thanks In Advance !. P.S. [Sorry For the bad english, If any ], Thank you !

I recently purchased G50-45 series 80e300gyin notebook with AMD A8 processor and dos based. Installed windows 8 and updated to windows 8.1. Also installed (Beema) AMD Driver (VGA, HDAudio, SATA) for Windows 8.1 (64-bit) drivers but still I am unable to adjust the screen brightness, by default it is at full. Please help me to resolve this issue.

A:Unable to adjust brightness- G50-45 80E300GYIN

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.

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.

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.

I suddenly was unable to adjust the brightness on this 3-day-old laptop.  Moving the slider from zero to 100% didn't change the light. I don't have an adaptive brightness setting. Google searches had me disable the sensor monitoring service, which did nothing. A user suggested rebooting while holding down Shift-F12 until reaching desktop.  This worked!  I can once again adjust brightness.  My questions: 1.  WHAT did Shift-F12 do?2.  Should I reenable sensor monitoring service?

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'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??

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.

Using the laptop on battery, when I press on F11-12, the brightness meter is shown on the upper left like usual, but it won't move up or down.  Yet I think it's strange that all other places I can adjust brightness are fine, and especially strange that everything is working totally fine on AC power.
I tried uninstalling the Generic PnP monitor and reinstalling, but to no results.  Also, both my power settings on battery and on power indicate no adaptive brightness.

Hello there, I need help please! I can't fix the screen brightness. It appears to be stuck on full brightness which draws my battery life quickly and hurts my eyes during nights. The brightness button in the action center is missing, there is no brightness slide bar in the display setting nor in control panel, and brightness fn buttons in the keyboard are not working as well. When I click on the battery icon, there is a brightness button next to the battery saver button but also not working (not even clickable).I searched online and I tried:- updating/reinstalling/rolling back display drivers- resetting pc (reinstalling windows)- many other little repairs College is starting soon and I really need my battery life and I will be studying on my laptop in late hours so this brightness issue is a big trouble for me

Beginning today, I opened my laptop from sleep and noticed the display was at its lowest brightness setting. I then tried to restart it to see if that would solve it, no luck. I did some googling and found out it could be a problem with the graphics driver. I then disabled it and enabled it. Now the brightness is at its max settings.

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.

This is the screenshot from my friend:

My screen brightness using FN+F11/F12 and also in the advanced power settings slider won't adjust the screen to anything other than brightness and minimum or brightness to 100% when I move the slider.  It shows the percentage moving up and down, but the screen stays 100% until I'm on the lowest setting,  then it goes right to minimum.  I received a bunch of Lenovo updates on the first Wednesday of this month and I've had several issues since then, I tried reverting back to previous drivers, but it made no difference, so I'm back on the latest drivers.

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.

Information: AMD-10 based Lenovo Win-8.1 laptop.

If you need any more information, please ask me for it!

Hi Hexillium and welcome to Eight Forums,
Ummm, have you messed up with start-up programs?.
Just give it a little check by going to Task Manager then start-up section and give me a screen shot.
I had this problem too and it could be because you disabled the driver from starting automatically upon boot-up, i had this disabled:

If you have the same program installed check if its disabled, if you don't give me a screen shot please.

I have recently noticed that I am unable to change brightness with fn + up/down keys, as well from display settings, or windows mobility center.
The value changes but the display is struck at certain brightness.i.e no effect if i make it 0 or 100.
I have tried updating the latest intel video driver as well nvidia driver from the vendors website, but no avail.
Though i can change brightness during the bios laod, but as soon as the windows logo comes, the brightness get sets to a certain value and i cant change it thereafter.
I think this problem arrived after windows automatic updated HD 4000 driver, now I have disabled windows update.

I know there are a lot of similar case with me but trust me, i have went through all the possible solutions that I have came across but none of them solve my eye discomfort situation.
So let me share again my problem here and what I have done in order to outcome the problem.
After upgrade to windows 10, my screen brightness can't be changed either using fn+fx or at power option or any other possible places.
Other fn button working fine. Troubleshooting:
1. Refer to ASUS driver and support website - useless due to obsolete driver.
2. Use intel driver update utility to scan and search for latest driver - installed but still useless - version a.k.a
3. Device manager --> update intel display adapter--> let me pick a list from my computer --> available and picked - useless
4. No brightness slider at power option
5. Adaptive brightness turned off
6. Device manager --> update intel display adapter --> Microsoft basic display adapter <<--- Seriously not practical but i tried anyhow but still useless.
The brightness is killing my eye. Anybody can share their solution especially from G551 or any user with 2 graphic cards.
Thank you.

I have installed a Windows 8.1 on my Toshiba Satellite A215-S4717. So far it is running OK. There is one problem though, I am unable to adjust the brightness of the screen in any fashion. When I go into the Windows Settings, for adjusting brightness, it says "Unavailable". In my previous versions of Windows & Ubuntu I have previously installed on this laptop, I was able to adjust brightness. I am checking to see if you can provide me with a driver download that would allow me to adjust the brightness. It does not look like any of the available drivers on the Toshiba website allow me to adjust screen brightness.

The funny thing is, that I am actually able to change the brightness on the Toshiba startup screen, however once the Windows mode comes up changing the brightness has been impossible. any help would be appreciated.

A:can not adjust brightness

Hi: If the brightness is stuck on maximum, you probably need to install the graphics driver. The problem is that HP only supports that model for W10. See if this W8.1 graphics driver works... This package provides the AMD High-Definition (HD) Graphics Driver and Catalyst Control Center for supported notebook models that are running a supported operating system. For notebooks with switchable graphics modes, this package includes drivers for both graphics processing units (GPUs). Switchable graphics enable users to switch between a power-saving graphics mode (normally used under battery power) and a high-performance graphics mode. If high-definition multimedia interface (HDMI) video output is supported, this package also installs the HDMI Audio Driver. http://ftp.hp.com/pub/softpaq/sp72501-73000/sp72773.exe

Ok I've had vista for a long time, but I switched over to XP and everything is perfect except from one small detail that is kinda big for me. I can't adjust the brightness in my laptopIn vista all I did was press fn left/right arrows to adjust it. And from what I know this is the way you do it in most laptopsNow in this XP I had to install all drivers. Specifically from this page http://www.laptop-software.com/acer-softwa...5738zg-drivers/when I install the graphics driver, VGA intel driver for vista is the one that's used for my computer from that list, the brightness just goes to the max apparently and I can't use fn arrows to adjust it. I CAN use fn arrows up and down to adjust the volume so there is definitely something fishy here. If I uninstall the driver I can use fn to adjust the brightness normally so I know the problem is when I install the driverthis brightness is driving me crazy! the driver bring something called Intel Graphic Media Accelerator which has an option for brightness, but it seems as if that's a different type of brightness cause it just makes the screen duller. You can actually still see a lot of brightness coming out from the computer but the screen is very dull. And it still damages my eyesany help?
