    I just changed their places from 1 and 2 to 2 and 1. I have 2 nvme, that may be tie with pci lanes or something. Try that.

    @Mr. Fox

    Alright, so I finally got around to replacing the display, but the flickering/strobing brightness remains. Would this be an inverter issue then?

    That display was a freakin' nightmare to deal with too. x___x The old one cracked as I was trying to take it out.

    Just up and down brightness throught fn+f11-f12. In first that will be 0-10%, but when flickering will not be on 20%, up from 0 to 20% etc. I fix problem exactly like yours on my laptop.

    You need to press buttons every second, 1 step up, 1 step down. When its be 20-50% of brightness for example, you must down 2 times and 1 time up. Its like 0-10-0-10-0-10-0-10-20-10-0-10-20-30-20-30-20-30-40-30-20-10. Try that. That takes 10 minutes for me, but it was an accident, to find out that solving.

    Hmm... it seems to flicker after 90% brightness no matter what I do, it stops after I go back down to 70%. I noticed the display flickers at any brightness when I'm not on AC power though, so when it's unplugged the problem persists, but when it's being recharged it sort-of works.

    Just for kicks, try disconnecting the battery and run on AC power only and see if the flickering stops. Curious if something electrical/power-related is causing it.

    I had the same issue a couple times. I believe this is an optimus-windows compatibility issue. Because I also had the same behaviour on my company HP laptop once last week. What helps is using windows+shift+ctrl+B key combo to reset gpu drivers. But this does not solve the problem always. Another way is if you manage to get to laptop to sleep, I believe it will wake up just fine.

    I would blame intel gpu drivers from WU, just my initial thought.
