The laptop used to operate properly, however now something has changed. The system is up to date, including dell updates. It works fine if it's on battery but with turbo mode, or plugged in, however as soon as you unplug it, it becomes super slow, unresponsive, as if it operates on 5V battery.

I have 64GB 4800 MT/s, 2TB NVME, 240V power supply, 12th gen Core i7-12700H, Geforce RTX 3070 Ti with Intel Iris Xe.

I'm sure it's some power settings but tbh I have no clue which, I've went through all of them and everything on the surface seems fine.

Not sure if it's windows 11 itself or some dell/intel software, but I'd appreciate the help if anyone knows what it might be or how to properly diagnose it.

Thank you.
