So after pressing the power button ... the system is On without Post, no Video, Fan not spinning ... what about the CPU is not heating uP ?
Also I had quick look into the schematic ... You know that U got two BIOS Chip ,, have U flashed both of them ?
Another thing ... this board is using DDR3L ,, meaning it wont take 1.5V RAM ...

Hi @piernov sorry for that I'll do it next time but the reason I did that is to organize the data I've gathered, it's readable when it is zoomed in though. Thanks for reminding me.

So You left the laptop oN for 30 minutes with CPU heating up and no FAN ?
With resistance I will not help You ... Yet I dont understand that topic .. sorry. But I know that it should be low as CPU got low resistance ... but I dont know what is the acceptable number.

HDMI, VGA output any luck ??
I just only reflash the Main BIOS which is U23 on schematic not the other one because I don't know what is the other one for.
I don't know what do you mean about DDR3L? The RAM is not on-board though.
VGA output not exist on this unit, HDMI output no signal.

EC Bios for SuperIO ... aka Start Up Chip. Sometimes this could cause laptop to not to post.
Next time when the fan cooler is not working ... just touch the heatsink If it is hot then You need to somehow start up the cooler... I am not 100% saying that the CPU is dead ... but 30 minutes without proper cooling... who knows.

EC BIOS reflashed same result.
I tested the unit for 30mins with fan (not responding) & heatsink.
My interest is at +VCC_VCCGI power plane doesn't look good to me. I hope someone can provide about it's nominal resistance value.
