Helo.

When I turn on my Laptop it start to work because I see the lights on and the fan is working, and the hard drive too. But I don't see nothing in the screen, only white screen, but no black.

I took everything out to cleaned the fan, then I put thermal past on the CPU and Graphic. I turn on the Laptop and nothing happened. Also, I took the memories out and tested one by one, and nothing.

I try to open the screen to check the Power inverter, bat, I read some articles about this Laptop, and I found that this Laptop doesn't have power inverter. Now I have a big problem.
