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.)

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??

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 !

Hi, Can you post back with the full Model No. and Product No. of your 15 series notebook - you can usually get this by holding down the fn key and pressing esc, otherwise see Here for a guide on locating this information. Regards, DP-K

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 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.

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...

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.

Help appreciated, I can't work like this.

Thank you!

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 ?

A:Windows 7 Enterprise x64bit [ Cant adjust screen brightness ]

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.

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 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.

I only found one other person that had this problem and he got it solved, but he had an Asus laptop and he got it fixed with some Asus drivers but i have a Dell Vostro laptop.

I've altered all the settings (as explained on other threads) but I still can't get to the centre of the problem.

since a reboot fixes it (at least temp.) it is probably not hardware but software. Do you have a backup from before the problem started getting worse?

Do you have the win 7 dvd to do a repair install?

Hi, I too have a Samsung Monitor (T220) which possibly - like yours - does NOT have the necessary software to link with the 'auto adjust brightness' system within the Charms Menu. You should however be able to adjust brightness (and anything else) via the controls which will I expect be built into the side (or along the base) of your screen.If you haven't already got a copy of your manual you can download a PDF from Samsung which will show how to make the adjustments you require.
