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?

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. 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.... :-)
