...

Hello all
i have lenovo g50-80 and my power source had broken cable (20V output) .
So i try fixed this ,but I did not study what the pin is all about. So i connected 20V to signal pin the middle one "ADAPTER_ID" pin (pin 3 of JDCIN1).... then i try plug in my "FIX" connector to notebook ,but immediately turn off , just dead .

So i pulled out the motherboard and trying fix it but dont know where to start .
Pls help i will try everything.

Thanks(and sorry for my bad english).
