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.)

Hi
     I have Dell Inspiron13 7000 series laptop.Everything was working fine until 2 weeks back.
Suddenly I wasn't able to use F11/F12 keys to controll brightness.Even if I clicked I wasn't getting the actual brightness bar.I checked some blogs and youtube videos, which helped me and it fixed my issue.
Suddenly after almost a week or so, I am getting another issue.I can scroll up or down the brightness however it doesn't change any brightness level.Right now it is too bright but I can't change it.
Has anyone been facing this issue or resolved this?
Laptop was in perfectly operating condition before.I have been getting these issues recently after regular windows update.

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.

Hello,

My laptop: Dell Latitude E5550 - 15.6" FHD - Core i5 5300U - Intel HD Graphics 5500 - Windows 7 Pro 64-bit - 8 GB RAM - 500 GB HDD.

Does anybody know what drivers/software is responsible for displaying On Screen Volume and Screen Brightness Indicator (while pressing Fn+F2,F3,...) ?

What I've found so far that the Dell QuickSet may does the work (link to this solution: No Level Indicator When Using Keyboard Audio Volume Controls), but I couldn't find a compatible version of this soft with Dell Latitude E5550.

Hi: Did you install the graphics driver?  That would be the only suggestion I can offer. This package provides the driver that enables the Intel High-Definition (HD) Graphics in supported notebook models that are running a supported operating system. If high-definition multimedia interface (HDMI) video output is supported, this package also installs the HDMI Audio Driver. http://ftp.hp.com/pub/softpaq/sp75501-76000/sp75508.exe Check to ensure you see the Intel graphics adapter listed in the device manager under the display adapters device manager category. If you see a Standard VGA Adapter, that means the graphics driver did not install.

I have a Lenovo y560 and the screen brightness juss keeps changing on its own, i try to set it to a brighter settingand it justs lowers itself back down within seconds, the laptop is also running windows 7 64 bit if that could be a cause.
 

A:Screen brightness changes on its own?

Your computer's got an ambient light sensor to detect and automatically adjust screen brightness based on surrounding lighting. You'll have to disable the setting. Lenovo has their own energy management program that has a setting for it, but I'd imagine there's something in the Control Panel (maybe Power Options?) that allows you to turn the setting off.

The P51 screen is brighter and also has almost no grain. That said, I would still like the P51 4K screen to be brighter than it is, but then I am a succer for bright screens also and is used to the XPS15 4K and MacBookPro 15 screens which are both the best in the business (Surface seems to be good to but have never used one). Its not like it is a problem to use the screen even in a quite bright room, but it is a bit "dull" compared to the ones mentioned above.

Hey guys

I have a very small problem here. I had a recent format to my laptop. Assume now that I am working on the battery. Whenever I plug in the AC, screen brightness increases perfectly. No problem here. Now imagine, I put the laptop to sleep or hibernate and I plug in the AC. Whenever the laptop comes from sleep or hibernate, screen brightness stays dimmed. I need to adjust it manually every time.

Did any of you experienced something similar to this one? I checked other posts but most of them are related with not being able to change the brightness manually. Nothing like my problem.

I appreciate any suggestion

I've noticed this happen twice. All of a sudden the screen flickered for just a second and the colors on the screen got brighter. By brighter I mean the the actual color changed (ex. my blue taskbar looked grayish). Both times my laptop was plugged in and the second time it happened I simply unplugged the computer and it changed back. After plugging the adapter back in the screen went to plugged in settings, but did not change the colors. The two times were separated by about two weeks.

I'm curious what might be causing this. It's probably just some little bug with a driver but I wanted to know what you guys thought.

Hi, I have been having an issue recently with newer games. The games I play now are starting to override my gpu screen brightness settings and reverting them back to original brightness.

Basically I have my screen brightness set lower than normal through my gpu control panel. When I play some of these newer games now they override my gpu settings and revert them back to normal, even after the game is exited. I have to then go back into my gpu cotrol panel and set it back to what I had it originally.

This has happened with 2 different graphics cards, Nvidia and AMD both using their gpu display settings panel. Which would be Nvidia Control Panel, and AMD Cataclysm/Crimson Control Panels. Also with different drivers. The games I've had issues with are Fallout 4, Warhammer Vermintide, and now Ghost in the Shell Online. So I don't know if its an issue just for me or if that's just how games are being made now to use their brightness settings to override mine. Any thoughts?

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

I'm not sure if this is in the right forum. But in the last couple months, once in a blue moon I couldn't change my screen brightness, and now in the last couple days it's gotten a whole lot worse. Usually, I can't change brightness either via my 'fn -/+' hotkeys or via the actual brightness slider in the power panel. A full reboot or simple hibernation then reboot both let me change brightness again. But the last couple days, restarting the computer just puts the brightness on either fully dimmed or fully bright, and I still can't change it.

This is an HP G60 laptop, and I've had windows seven for a year on it. Like I said above it only started a couple months ago then got worse this week, and what I've found on google so far was all for newly-updated-to-seven issues. My drivers all seem to be up to date according to the windows update driver function... Can anyone help me?

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?

So, a few days ago the battery of my laptop died and when I charged it and power it up again I found that I can't change the brightness of my screen which I was able to few minutes before.
