I just discovered the problem.

So in the event viewer i have a Kernel Power 41.

Yes but the thing is that the laptop only reboots when the AC is plugged.

So it means that the GPU only works when the AC is plugged, I only the laptop for WEB and some Office Work.

No, you have a problem with the laptop at the hardware level. You need to contact the workshop to repair your laptop. In your case any modifications in bios won't help you.

I am an IT technician and I have a workshop. 

The thing is i can trick windows into thinking is on battery power but with the AC plugged in.

It's maybe possible to tell the system that the AC is not connected, like disabling 3D states. The computer is rebooting as soon as something needs the GPU but only happens on AC.

I think no. You can try to remove the graphics card from the laptop and then see what happens.

The laptop works without the graphics card?

I can try to change the GPU but at I it is too expensive, it's not worth it.

Is it possible to fix the GPU (570M) by baking it?

Hi,

I have a GT683DXR that reboots from nothing on AC, I think it's the 570M that is giving up. I wanted to flash the unlocked bios for it to check it changes something.

Is it happening to someone?
