Hi to all!
It works! I've tried and now 100% working:)
There are two methods to solve the problem:
first
1 - Remove the computer and remove the motherboard.
2 - Remove the processor card and the NVidia side.
3 - Remove the CMOS Battery - there is a problem - this soldier with two metal parts. Solution: desolder and re-welding end.
4 - For the motherboard in the oven at 200 ° Celsius for 5-7 min. (Do not be afraid there is no problem, do not melt)
5 - Turn off the oven at the end of time, open the oven and windows and leave the kitchen for 20 to 30 minutes not to inhale toxic fumes.
6 - During this time the motherboard cool slowly.
7 - Remove the card and mother board and assemble the laptop.
8 - Connect the computer and run it.

PS: This method doesn't work for me at first (i did it three times and nothing).
NOW Plan B
Second Method (With a coin)
1 - Burning a bronze coin in the flame to change color.
2 - Quick, put the coin on the GPU and heat in two ways for 15 min:
2.1 - with a 100w lamp
2.2 - with a metal welder, by putting up on the coin to not let it cool.
( if doesn't work try more times) I've done it and it works!!
3 - During this time the motherboard cool slowly.
4 - Remove the card and mother board and assemble the laptop.
5 - Connect the computer and run it.

-(Pasta de silicona - i've not put it... it works without it)
I am not a computer technician,..... so you'll also get it;)
It seems that the defect is in 5520G . . . but we can solve i;)
Thanks to all, My laptop is working now!
Thank you!!
