Question

I can't adjust or change my screen brightness with the hotkey (F11 and F12) or with the slider in Settings. This happened after I updated to WIndows 8.1.

Answer

Installing the Intel card driver may fix the issue, however, iinstallation of the drivers below is also recommended to ensure the brightness issue in Windows 8.1 is addressed.

Thanks,

I am using z500 touch. I updated windows 8.1. I used for 2 weeks almost. One day just by chance, I touched F12 key . My screen all the way went very dim. Intel driver reinstalling helped me and it worked.

After that I faced a new issue, My touchpad stopped working 100%. Now its zooming in and out is not working.

Go to Control Panel>Display>Adjust Resolution>Click advanced settings>click properties>click driver tab... After you click update driver, it will ask you "how you want to search for driver software;" click "browse my computer for software" then next window choose "let me pick from a list of device drivers on my computer;" you'll see compatible drivers, look for "Microsoft Basic Display Adapter" click next>

 

-I did it and its back to normal brightness!

There is another thing that can cause this, as I found out, and it is the installation of TeamViewer.

This can install a "monitor" driver over the old one (something to do with black screen setting I think).

 

If you go into device settings, check the provider of the monitor driver. If it is Teamviewer, then uninstall it and scan for changes...make sure you end up with the Microsoft driver...

Use basic display driver or update to the new driver if available for 8.1 Windows 8.1 Can't Adjust Brightness

Dear

 

After the installation of Windows 8.1, I had noticed  that the brightness of the laptop went down considerably low. Even by increasing or decreasing the brightness (F11 and F12) situation did not improve. The solution is a simple one. One just needs to re-install the graphic drivers and upgrade the Lenovo power management.

I have an ideaPad p400 Touch. This happened to me in 2014, after I installed Windows 8.1. I updated the graphics driver and it was ok. Now, after I installed an Office software update, it happened again. I updated the basic display driver, as instructed by ddelatorre14 on 05-27-2014(above), and my laptop screen was bright as a new penny...but also totally unable to detect my second monitor.So, still with one screen! So I rolled back the updated driver, and now it is working, but I think only temporarily. There seems to be something about hitting F11 or F12 that makes it go to the dimmest setting and stay there. So, I may be back...

I have a  s215 that I've downgraded to Windows 8.1 64bit. For the most part I have everything working. I can't adjust or change my screen brightness with the hotkey (F11 and F12) or with the slider in Settings. This happened after I updated to WIndows 8.1.
