Hi,
My laptop went dead and after checking ,the main 19 volt power rail was shorted. After some checks i could identify that a high side vcore mosfet was shorted.
I replaced the mosfet and now the white powerled is present , fans start spinning but capslock shows the famous 5 long and 3 short code.

I checked the vcore voltages after replacement and i get for all 1.01 V so means for me that the driver is still working of the replaced shorted mosfet. On the Nvidia i measure around 0.8 V after the mosfets.
I did voltage injection on the cpu with 0.7V and i have a current...

Hi, i am a electronic hobbyist trying to fix my own broken tools as much as possible. I see a lot of experienced people in this forum. hopefully they can help me out.
