I have a HP Spectre x360 - 13-4009na and have just upgraded to Windows 10. The problem is I cannot alter the screen brightness using any of the usual methods.
- The fn buttons do not work
- There is no brightness control displayed on the Control panel - Power Options
- The Calibrate Display Colour method fails with an error while "... preparing to calibrate ..." - "Unspecified error".
So my display is set to high brightness and I cannot change it. Please can someone help?

Omg, I had the same issue too. I kinda tried changing it with the AMD driver (that I had to re-install after the Windows 10 update) it was pre-installed when I first got my laptop, anyway besides the point, I used it and it kinda changes your brightness, but not the same way as using your brightness control buttons to. I hope that helps much, It didnt exsctly satisfy me. But the AMD driver (if you have a laptop) is a great driver that runs your graphics really smoothly

I fixed this on my Envy 15 j151sa -
Settings > Display > Advanced Display Settings > Display Adapter Properties
Then Properties > Driver Tab > Update Driver button.

uugghhh, im having the problem again. This time the cause of it was me updating the AMD Driver to its newset version and I couldnt change my brightness so I tried to updated it, and it woulddt allow me to so then I tried down grading it and still couldnt change the brightness. so im just like my pc is becomeing a piece of crap. 2 USB ports dont work, my keyboard dosnt work, (which is kinda my fault) and I cant even run the printer on here. so its practicly internaly falling apart.
