Samsung NP305E7A DC Power Jack Repair – Replacement

This Samsung was brought in for a DC Jack repair, The DC Jack seemed pretty loose, so after taking the  laptop apart i noticed that the main motherboard had a very bad burn mark on it, turns out after some diagnostics that the LCD Hinge came loose and the metal shorted out against the DC Jack/Fuse area, So I installed a new dc power jack and did a fuse bypass.

Now the Samsung powers right up and charges fine.

MainGear ( Dell) P151EM1 Dc Jack Replacement | Repair

This was a Drop off repair, the customer had issues with his charger shutting off and the keyboard was not working.
After taking the Whole Gaming Rig apart I found that the main Center Pin to the Circuit board was was cold solder burnt
meaning that the main 19 volt center pin was not 100% connected creating a arc type of connection, so i de-soldered  the old dc power
jack as it was loose and worn out, I installed a new DC Jack and also ran a Separate wire from the Back of the DC Power Jack to the main
fuse so there will never be an issue of power not getting to the motherboard! I also cleaned the entire unit and used chemwash to clean the keyboard
as the CRTL key was not working, now this laptop charges to 100% and the charger does not shut off anymore!
