I'm on ACER laptop (v3-371 with Intel HD Graphics 5500), running Windows 10. The issue I'm struggling with is the screen brightness that keeps automaticaly adjusting when I'm running on battery. I've done a lot research but I'm still unable to fix the problem. Here is the list of the things I've done so far:
Disabled "Display Power Saving Technology" in INTEL Graphics Control Power
Disabled "Adaptive screen brightness" in Windows Advanced Power Options
Uninstalled and re-installed the latest Intel HD Graphics drivers from the ACER site (I was unable to install the drivers downloaded directly from the INTEL site - the install dialog box told me that I need to get my drivers from the laptop manufacturer's site)
