I have a lenovo legion y520. I wanted to replace the keyboard because the O key wasnt working anymore. Its an embeded keyboard in this laptop.[br]
Anyway I replaced it.[br]
After that, I maybe damaged something in the motherboard. The cable linking the lcd screen and the mobo burnt because I connected it after the battery.[br]
So I have to take a small aluminium circle that felt from the case to make contact with a circle area in the mobo. When I do that the Mobo start (white led)[br]
Here with the mobo only[br]

The fans wont spin[br]
I dont know if the fans have to spin anyway. I dont know how to test if something is damaged. Indeed the lcd cable seems to be burn so Even if I connect the laptop with a hmdi screen I have nothing.
Look at this video I did : https://streamable.com/hzz5v[br]
Someone can help me troubleshooting this ?
Sorry for my bad english ^^
=== Update (01/04/2020) ===
The connector seems to be ok even if the plastic burnt a little. The metal connectors seems to not be damaged.
But the lcd cable ( I ordered a new one) burned.
Here some pictures

I dont know if the laptop is working or not because there is no display and the fans dont turn on…even if I plug a hdmi display.
I heard that heating the Mobo can be a solution

Thanks for your help.
I ordered a power button and display cable.
Do you think this kind of power button is OK ?

Also, is it possible that this screw is responsible for not let the laptop boot normally ?

Note that this part is connected with the CMOS.
Normally the screw has to be in the metalic support like here

By mistake screwed directly on mobo and…the screw is now broken impossible to extract, I will cut it gently to unscrew it with a flat screw driver.

Hi everyone,[br]
[br]
I have a lenovo legion y520. I wanted to replace the keyboard because the O key wasnt working anymore. Its an embeded keyboard in this laptop.[br]
Anyway I replaced it.[br]
After that, I maybe damaged something in the motherboard. The cable linking the lcd screen and the mobo burnt because I connected it after the battery.[br]
[br]
So now I have several issues.[br]
[br]
First the powerbutton seems to be damaged[br]
