P1 gen 4 with the i9 and rtx 3080. Pay close attention to the power levels under heavy load. It will drop massively under long term heavy loads to try to prevent the battery from discharging. My machine only takes in a little over 170 watts from the power supply, but with a laptop cooling pad it can easily sustain over that 170 watt mark. It doesn’t happen instantly, it starts when the laptop is fully heat soaked (takes 30+ minutes with the cooling pad). You won’t notice it until about an hour or two in, but once it starts it will start accelerating as the battery heats up. Shorter loads that the laptop is more designed for it handles it just fine. It’s only when you push it for too long and too hard.

Also whats the power consumption of the mobile 4090 like sitting on but idle? Random programs trigger my 3080 for no reason and that GPU draws about 20 watts minimum. I want to upgrade, but I’d lose vram if I got anything less than the 4090 and I don’t know if I want all of that excess power draw when the system can barely benefit from it, and it makes using it as a laptop awful.
