Problem with shorted GPU? or just haunted board?

Troubleshooting Laptops & Notebooks - Badcaps Forums - www.badcaps.net
Hello,

so where to begin...

EA/VA70HW REV 2.0

Laptop no power, only smoke coming out from area around adapter connector.

One of two power mosfets where making smoke so I removed it.

I will add a photo for reference (not my board in photo)

Connected power supply to adaper connector and board was taking 0.200ish A and fuse "220" did heat up. I replaced it with different "220" but it caught on fire... so I used "2R2" fuse, don't know what's the difference but no fire and no more 0.200 A. Instead it goes from 0.000 A to 0.080 in 6 seconds and stays like that. (did this without having 2nd power mosfet)

But now when I connect power supply to 2nd mosfet pins I get short and GPU is heating up...

Why?

Thank you for your time,

Raitis
