I have an Acer 5570Z i bought a while ago. It was having problems charging, only when i jiggled it the right way would it start to charge. I took the laptop apart and found out that the power jack has broken off inside. It is a plastic piece. Well i tried a few things to fix it but none have seemed to work. I tried superglue, a glue gun, and melting it back together, none worked.
So if anyone has the hookup on getting parts let me know. The part number is DA0ZR1PB6D1
And here is a picture of it. It is going anywhere from 120 bucks to 74 bucks.

It is that yellow piece that has broken.
