G15 5521 Special Edition

I don't think my laptop is technically Alienware but from what I've been able to find, I think a good amount of the hardware is available on Alienware laptops so I'm hoping it's ok to ask here. I got my laptop 3 months ago as a replacement for one that was damaged and not able to be repaired. They didn't have a laptop similar to the one that I lost so this is what I got as a replacement. Anyway. It has one quirk that I find to be really weird and disturbing and I'm not sure what's going on. It was set to hibernate or sleep (can't remember and don't know the difference) when the lid is closed. I don't know what would be running when the laptop is sleeping or hibernating but apparently something is because last night the fan kicked in and got a lot louder than normal. It was making so much noise that I had to go check it out because it sounded so unusual. I went to pick the laptop up and it was so hot I was a little hesitant to even touch it. I didn't sign in to see what was running because I didn't have anything open when I closed the lid earlier so instead I just shut it down and flipped it over so the fan was getting more air circulation.

I don't use it for gaming but have noticed that it gets warm when I'm using it. That's not a big deal. I am concerned that it apparently does stuff while it's closed and should be sleeping, and that whatever it's doing is causing it to get really hot. Is this normal? And is there a way to find out what's running when it's closed and should be sleeping or hibernating? I changed the setting for what it does when the lid is closed so now it shuts down completely. At this point I'm guessing the machine is probably possessed. (Kidding obviously.)

(It's running Windows 11 Home edition I think, and then there's all this stuff:
Processor 12th Gen Intel(R) Core(TM) i7-12700H 2.30 GHz
Installed RAM 16.0 GB (15.7 GB usable)
System type 64-bit operating system, x64-based processor
NVIDIA(R) GeForce RTX(TM) 3070 Ti 8GB GDDR6

Thanks.
