Laptop COMPLETELY dead. Not a single indication of life.

So.. Im gonna try explain my best, and not to forget anything.
Laptop: Acer Aspire TimelineX 3820TG

Issue:
I turned off the laptop, in a correct way because I was moving it to a different house. Nothing happend on the way to the house. Suddenly, it wont boot... It wont boot at all, neither will it give any sort of indications of life, like any LED's blinking or something. It's completely dead.

I have tryed like EVERYTHING, even my own experiments with no luck..

I have tryed swapping RAM's, I have swapped HDD, I have stripped it all down, so the motherboard is outside the laptop with CPU&GPU fan, power cable and boot button connected.

I have removed the CPU and replug it... I have tryed every way regarding with/without AC/DC/Battery n such.. Changed CMOS battery. I have even done some experiments.. I connected a VGA cabel from a powered on laptop, to my dead motherboard. THEN!

Then I got a minor indication of life. I heard a very small noise from the CPU fan, and it looked like it wanted to start spinning. I can make it spin if I help it start by spinning it manual, lol... But thats all...

In other words, I have done like everything you can imagine to get some life indications. Please give me some advices, the motherboard CANT be dead, it cant die just like that.. Wtf.

Could a bad cable from CPU fan be the whole problem? Help my arse please.

P.S: I have no multimeter... The AC/DC power thingy is working, I have tryed 2 different kinds with no luck.
