After two hours of disassembling...
(Okay, it took me a lot of time because there are many traps! 30+ screws where some are hidden!)

For the first time, I have a close look at the internal components of a laptop.

It looks cool outside.
At the inside, it's nothing more than the electronic stuffs I see in my lab.
Yeah, as ugly as it is.

So, the motherboard has died and all other components "look" good.

Maybe, I will send it back to service center for it to start a new life.
Maybe...
