Question Max board power draw on laptop results in power-throttled GPU ?

[survivioplayer]

Laptop model: Gigabyte Aorus G7

Behavior is usually normal on reboot, but randomly pushes the GPU power draw to 590w and irreversibly power limits it until I reboot again.
Games run at 5 FPS or so slow that physics [ PhysX? ] slows down when in power limited state.

Hey there,

Is the GPU a RTX3060? If so this GPU can only draw 105w. The power brick for the laptop is prob about the 230w mark. There is no way your GPU could be drawing that much power.

What are you using to monitor the temps? Are all system drivers, including chipset up to date? What about bios?

it's a 4060, it probably can't actually draw 590w but that's what GPU-Z and MSI Afterburner report whenever it happens.

WHat does HWInfo report?

It says GPU core voltage 0.625 W lol which checks out, GPU power is also 590 W

It must be a bad sensor. Nothing else would count for that. But if the GPU is reading the sensor info, and working with that, it's probably reasonable it's throttling. Not sure what else you could do.

Have you disassembled the laptop? MIght be time to inspect the inside, and see if there is some damage. You haven't dropped the lappie or anything have you?

It has fallen off a chair inside a backpack and the screen bent a little but returned to its original shape, still performed normally for rest of the school quarter, only started throttling power since June. It always had this weird issue where it'd sometimes shut down while lid down for too long. And yeah I should get to disassembling the laptop, no obvious signs of battery damage or swelling so no major leads thus far but I suspect maybe it's some weird problem with the battery or adapter.

I think it might be worth it to disassemble and clean out fans, and replace thermal paste on both the CPU and GPU dies. Note: In a laptop the CPU and GPU are bare dies, which means you need a viscous thermal paste so it won't degrade quickly (pump out effect). Noctua NT-H2 is good for laptops.
