Fix Windows 10 Brightness Settings Not Working: While the Windows 10 is the latest edition to Microsoft Operating System but it’s definitely not bug-free and once such issue is Brightness control not working after upgrading to Windows 10. In fact, Display related issues are very common on Windows 10 which is why users are very frustrated with. Right- and down-arrow don't work, i.e., when I press one of them nothing happens (but I don't think they are physically broken); there is no way to access the brightness control, neither with fn + right-arrow nor by means of the display settings available in the control panel (the slider does not appear in the proper page of the control panel).
I have a SurfacePro, Windows 10, and my brightness buttons do not work. I know it's not the end of the world, but it's just driving me crazy and if a button won't work on a fairly new device I think that's a problem.

I started to look for help online, andthe only 'solution' I have found is the method where you go to Device Manager, Display Adapter, and update that. And then if that doesn't work to switch it to Microsoft Basic etc. This did not work on my computer and I tried it more than once. So, what doI do to fix this? There must be a way. And it's also crazy that so many people are having the same issue, seems like a big defect.Moved from: Windows / Windows 10 / Devices & drivers / PC.

However, if you want to manually adjust the brightness using yourSurface keyboard, hold down the Fn and press the Delkey to adjust the brightness or hold down the Fn and press theBackspace key to dim the screen.
