Lenovo Dell Sony Toshiba Acer Asus. You can not only experience the screen brightness on Windows 10, but you can also encounter this problem in Windows 7, Windows 8 and Windows 8.1 operating systems. Laptop users can use the FN + Brightness Up / Brightness Down keys to adjust the screen brightness.If this method does not work, we will resolve the problem that the screen brightness does not.
I have a Lenovo laptop that I purchased with Windows 8. I recently upgraded to 8.1 and now the function key to adjust brightness does not affect brightness. I went into the power settings and made sure the slider on the brightness level was at its highest level. Cannot seem to figure out why my screen is so dark. Have you tried turning it off, then turning it back on?Sorry, that really is the first thing that comes to mind.If the answer is 'Yes, I have, smartass, but the problem isn't gone', then it sounds like the display driver somehow got corrupted. This might be a long shot (that too in the dark) but do you use TeamViewer, and if so, did you recently try installing its monitor driver?- Nick.
Lenovo puts in special device drivers on their laptops to enable special lenovo only functions. They made a custom build image of windows 8 for your machine and added these features (drivers). To have these work you need to get device drivers from Lenovo web site and the upgrade from them.It is easier for them to tell you to go back to windows 8 and never upgrade and they put out a list of laptops that they will not support if upgraded.Also, a nice list of what will not work if you do upgrade. I would recommend that you complain and get them to provide drivers with proper setup programs for them.to work around the problem, see lenovo has a driver update for your computer to make your button work. If you can not get it, then you have to use the graphics vendors control app to tune your graphics adapter's setting to the way you like it. (download app from the graphics chip vendor). Hey t4akawolf.I had a same problem that i was not able to change screen brightness of my laptop.I spent almost 4-5 hours searching for the same on google but could not find it.
Lenovo Computer Brightness Not Working
Most of the people suggested to re-install the graphics driver or switch to basic display driver etc. But nothing helped.Just uninstalled team viewer monitor driver after seeing your post and it solved everything in a minute.So your post helped me a lot and saved my time.Thanks.You're quite welcome. I am glad my post helped you.Do come back to tHW for any future problems you may face!- Nick. I have a Lenovo laptop that I purchased with Windows 8.

I recently reinstalled team viewer again and while insta;lling VPN driver i also installed the monitoor driver. I would have never even thought of this since i installed it a few weeks ago.

This might be a long shot (that too in the dark) but do you use TeamViewer, and if so, did you recently try installing its monitor driver?- Nicknow that resolves my issue as soon as i uninstall my Teamviewer Monitor driver the adjust screen brightness option came back. I have a Samsung Ativ Book 8 that I am running Windows 8.1 on. Its screen brightness was stuck on bright, as in bright enough to confuse it with a small star. This is only a slight exaggeration, I can assure you. The problem was that Microsoft changed the programming behind how the display drivers worked and did not include the driver update in any part of Windows 8.1. However, when I logged into the AMD website (old fashioned, I know) and downloaded the new driver manually, after changing the AMD catalyst control center settings, everything works beautifully with changing brightness and is universal across all applications/programs.
Therefore, with anyone having problems like this, I recommend going to AMD, Intel or NVidia websites, depending upon your hardware and manually installing new driver updates.I hope this helps.Cecil Neville III.

This might be a long shot (that too in the dark) but do you use TeamViewer, and if so, did you recently try installing its monitor driver?- Nickthanks man. That for me really was the answer, teamviewer. It seems this takes away the slider for brightness and leaves my monitor in a permanent state of full brightness. Uninstalled the monitor driver only and voila immediately upon removing everything came back to normal. I have a Lenovo laptop that I purchased with Windows 8.

Show Advanced Options. Scroll down to 'Advanced network settings' and clicked 'Uninstall' next to 'Install monitor driver'.
Immediately my eyes weren't straining anymore. I can see clearly again. I wouldn't even have thought of TeamViewer since I've done this on many other PC's with no problems. What a relief.Thanks.
