      i was getting kinda exited to try something like that but then I check and PPBUS_3GH has a short too , then I inject voltage 1.6v and I find the part of the board that was getting hot , man damn it , one of the screwholes is fucked , I remember when I start taking out the board from the laptop I saw a screw that was to big for that position but I didn't pay attention on that moment , im going to take a picture tomorrow to show it here , I belive the short is on that screw hole it look a little destroy like is missing a little piece of board , I check under microscope another board and yea that give the truth , this was fucked for a screw , was clean from all water damage before that board get to my hands and then when they put it back they put the wrong screw and now I belive is beyond my skills im letting go this board....

      Louis with your power you think if a board like that get into your hands you will be able to rebuild it? I know you will not do it because of the 20 minutes rule , but you think is possible build your own PPBUS_3GH?

        Carefully grind out the screw hole. This should clear the short between the layers.

          it would make a fun challenge in a world where I had more than two employees and just me for fixing boards. but in reality.. no time to figure that out.

              You have to do it very careful and slow else you will still be mashing the layers together. I use a very thin round file for stuff like this. Do not put pressure on the file, just use it's weight and go very slow.
