How to disable Toshiba Satellite L665-1H7 discrete graphics card?

Question

Do it yourself

There is a laptop Toshiba Satellite L665-1H7. Does not turn on. The fans are spinning, there is no image on the screen. Through vga, on the monitor too. I was disassembling the laptop and saw a chipped graphics chip. If you just unsolder the nearest inductor, then the chip stops heating up in any way. But everything stops warming on the mother, and the end result will be the same.
I rummaged through everything in search of a scheme, found some one, but there is nothing about it.
I found a thread on the forum where they say that this is impossible, because the video card gives an image directly to the LVDS.
