820-2850 fan spin 3 seconds and stop, then loop

On other boards I've checked, this voltage was always present.
Seems that is not needed now.

You can try disabling GPU.
Required information should be already posted on the forum.

You have given me a zipfile before that contain images to bypass GPU but I checked the details it seems like it is actually just disconnecting gpu datalines around gmux and solder LVDS directly onto iGPU data lines, without actually disabling/power down the GPU chip. Maybe I have overlooked?

On the 820-2915, you told me I could diable GPU by removing R8904/11. But if i remember correctly, I cant do the same on the 820-2850. Is there a way to just power down the GPU on these 2850 board?

You should also remove corresponding resistor which powers up GPU controller from its power supply.
But is not sufficient to stop the GPU power.
