My laptop does not flicker but the  brightness adjusts, how do I fix that? see details ?

I have a Samsung laptop 950QCG.

It does not “flicker”, but I usually set the brightness low. When I turn on the computer on and log in, it adjusts the brightness ever so slightly for the first few seconds and then stabilizes the rest of the login session. You must stare to notice it, but it still concerns me. When I turn it off and it goes to that blue log off screen, it does the same thing.

Only one time did my screen turn black for split second. I had this computer for about 2 months.

I reset the drivers by pressing shift+ control+ window +b. But I still have the slight brightness adjustment.

I thought about sending it to Samsung while it is under warrantee, but they want you to box it yourself and send it out. What if I don’t box it well? I don’t want to do that If I don’t have to.

To note, this does not happen when the brightness is set real high.

I saw some complicated instructions about deleting the driver by going into safe mode, etc. but that scares me lol. And I don’t know if that is the exact issue.
