I am assuming you weren't plugged into a surge protector when you lost power. During power outages, spikes in voltage occur, so what happens is there's no mechanism to interrupt that spike by grounding, which surge protectors are designed to do. Any laptop/computer components cannot handle this voltage spike as they are delicate to certain voltage tolerances. I hate to say it, but your laptop is toast.

it have to be like in this pics:

Is this from startup, or does it crash after running fine for a while?

It's most likely not the power supply. I have a customer with the same problem. I used a power meter to see if the power supply worked and it checked out perfect. (You should still test it though, just in case.)
The only thing I can figure is a bad motherboard. Unfortunately, there's no visual signs of overheating, arc burns, or the like on this one to make it obvious... just one capacitor (the small one nearest to the power port) that has a slight bulge.
These things don't seem to be build to last, from what I've been reading.
Options:
-Break it down, sell the parts that are likely to still be good (wireless minipci card, memory, processor, heck - maybe even the front ports if you get longer cables/extensions), and maybe make around $200 that can be invested in a reliable machine.
-Or drop money into replacement parts. (but after what dj said about a second mobo going bad, I don't think it's worth investing more in this)

Ive had the same problem died on me and wont switch on but I found itas a different capacitor on the board same value as the one mentioned I replaced the 1st one and stikk didnt work so replaced the 2nd & 3rd cap as they looked swollen and it worked, I couldnt find a 6.3 1000uf so I used 63v 1000uf slightly larger but fitted ok,
I dont know if it was the 2nd or 3rd cap that was faulty as I replaced both at the same time.
See the image attache and you can see where they are located also you can see they are swollen
Oh forgot to mention make sure you use high temp caps to replace them ie 105c
