now we will loosen the cable's from the main board.

remove the DC jack cable connected to the connector on the main board.

Be careful when you do this, it is a very weak plastic connector ! i recommend using a small flathead screwdriver or a plastic spudger...

in the picture you see me using a IC axtractor, but i don't recommend it when you are not used to repair laptops...

when you are dealing with an broken DC jack , remove the whole cable ( black and red) running trough the plastic frame of the laptop...
