So, from the beginning. My AC adapters pin got worse and worse until one day i replaced it and the good old AC/battery switching started, as a poor student i bought a cheap adapter wich held to low amp, one night it broke down, i opened it and the AC connector was black on the edges from overheating. Stupid as one can be with to much alcohol and no computer else then the broken one i tried to plug it in again wich created some sparks, i have now recieved and replaced the old AC connector and got a new charger from asus 110$ they charged me for it, and guess once, it isn't Starting.

Tl:dr AC adapter broke, bought cheap one, AC/battery switching problem fried the AC connector on Mobo, tried to plug it in again, Sparks was created, now replaced AC connector and adapter, still aint Starting.

So did i short the mobo when the Sparks came around or whats your take on this ?

Take it apart and test your connection like in my tutorial.


If you have a direct short between the power pin and the ground you should try to clean up any excess solder to make sure it's not bridging any points. If that doesn't work then remove the jack and see if there is a direct short in the board. If there is then you're going to have to remove the short by removing a part of the motherboard. I usually use a dremel at very low speed. If you go too fast it will start to bridge the layers (you really don't want that to happen).

I'll give you an example of a g71 board I repaired.

You can see how much of the board I had to remove.

Let me know what you find.
