Have a Asus Tuf Dash F15, i7-11370H 3050ti mobile, and Ive found with the screen closed and when gaming, once it starts getting loaded it will just randomly suddenly just shut down. When I run cinebench almost on a timer at 7:58 it'll just shut down, not timer on prime 95 but about 2 minutes in it'll shut down the same way. And yes the power settings is set to ignore the lid closing.
However if the screen it up in the on position, doesn't have to displaying anything and I've check it both ways, just up that far, it'll game or run either benchmark till the cows come home, and I don't have cows.
Both fans are clean and purring right along. I've removed the stock thermal paste and replaced it twice with noctuas offerings and any time the lids up it pures right along, if it's down, like clockwork it'll shut down right about 2 mins into a benchmark or in the middle of a game session when it's getting loaded up.
The vents on top aren't moving any air when it's up so it's very "odd" to say the least. I've covered them up and didn't make a change in temps and it didn't shut down. Doesn't matter if it's on a laptop cooling pad, not exactly the most effective I know, right side up, upside down or one it's side if that lids down it's shutting off on ya if your doing more than word or YouTube.
And just noticed this as I'm typing, if I have the built in displaying anything, extended or duplicate it runs about a 5-7deg cooler average than if it's set to blank over the same time frame with no max temps above 94, most are barely above 90/91. Turn it back to only external and the temps creep up with max on 2 cores hitting 97 and 1 at 95 and one at 94.
So anything thoughts or ideas before I find a lid switch and remove it lol. And yes, already on the latest driver's and system pertinent software I can find for all the manufacturers involved.
