This in a Intel graphic thing. So go in the "Intel Graphics Command Center", left menu: "System", last tab "power" and you should find an energy economy setting toggle button (the one with an associated slider). I've just disabled this "feature" and now brightness is stable.
Note for Dell: since I have my laptop, I had many issues. Defective trackpad, replaced but then broken hardware (screen pivot axis, backplate internal plastic stuff) by those who replaced the trackpad on both machines I struggled to find that awful adaptive brightness stuff. But the worst part of that poor Inspiron experience, every time I ended up on that forum, I see the frustration of people trying to just use their machine, and you ignore us. The machine can't go to sleep mode while charging? No answer. Broken trackpad? No answer. Display issues? No answer. Why should we buy your machines if you totally let down peoples after that? the client 'support' is a nice waste of time.That would be a joke but it not even funny.
I wish all the happy Dell customers would post here Of course you will read a lot of complaints in a forum. You can't judge a product's quality by what you read here.
I had this problem with my 7506 which is just over a year old now. There were no settings that could turn off the Adaptive Brightness feature -- even though settings, BIOS, adapter properties might make you think so.
Eventually, Intel provided a fix in an update last fall. The fix also resolved some active pen issues I was having with one software product I use.
Man you saved me. It's their problem not noticing this annoying brightness change. Now I just closed the display power savings and leave adaptive brightness and panel self refresh on. Works fine so far.
I don't know if this is still relevant to anyone, but unchecking "Help improve battery by optimizing the content shown and brightness" under System > Brightness worked for me: https://support.microsoft.com/en-us/windows/content-adaptive-brightness-control-in-windows-292d1f7f-9e02-4b37-a9c8-dab3e1727e78

"What makes you think?"
My experience with the laptop.
Also I tried the link you sent. The "Display Power-Saving Technology" checkbox is not there.

To Enable or Disable Adaptive Brightness in Power Options
This option will affect all users that use the same power plan you set this for.
1 Open the advanced Power Options for your power plan.
2 In your current active power plan's (ex: High Performance) advanced settings, expand open Display and Enable adaptive brightness.
3 Turn on or off Enable adaptive brightness for what you want, and click/tap on OK.

I think I've fixed it on my inspiron 16.

It's a shame... (Yes I'm frustrated too)

Finally landed here after weeks of searching and frustration. Fixed it on Latitude 7560. Thanks
