Windows 10 Brightness Issue

OS-X Sierra is doing the same thing since 10.12, but with the Keyboard back lighting. I have a Early 2015 Macbook Air. Even Linux is having this same issue. I take it that Hibernate is shut down and Fast Start, by going into Command and you have done the following command "powercfg /hibernate off". Even with Hibernate off, I have seen some games that when they use WHQL or Directx, exiting causes the resolution to take a while to change or the screen goes into a dim mode. That has been going on for a long time. I am guessing that the drivers for ACPI that the OEM's and the OS companies are using, the newer code to try and squeeze as much life out of the battery, along with the whole LiON issue of them causing fires, they are made some changes to try and keep the temp of the battery packs down. Especially when they the likes of Apple and other vendors that are making the motherboards smaller to place the flatpack units inside the case to take up all of the empty space.

Does anyone know the solution ?

Again, no because this is a wide spread issue across all Operating Systems because of the issue with LiON Battery packs catching fire from overheating. The ACPI code has been changed and the Kernels updated to be better at monitoring battery temps, so that they do not charge too fast enough to get hot to catch the unit on fire. But also able to allow people to squeeze more battery life out of the battery pack, by making the Kernel for the OS better at handling how it uses the battery power while it is treated as a UPS when plugged in and when on the go as what are now becoming throw away devices with those units that are factory sealed in a way to keep people from opening the units and swapping out the RAM modules or M.2 or Sata drive that would be a SSD on most.

OEM's are getting smarter in selling more throw away devices by the way that they have done what I mentioned above.
