I have an HP laptop Pavillion N5475 that I have not been able to use for over a year. The power jack is defective; and the unit is out of warrant. I took the laptop apart, and remeove the circuit board that houses the jack and re-soldered the jack in place. Re-assembled and ... no good. I need to replace the jack, but do not know where to look for parts or how to describe it / identify it in proper terminology. Can anyone help me identify the jack and help me acquire a new one. I can send a pic of the jack. I know it is a coaxial type but am unsure of the size "letter" and whether or not I can purchase a jack that will match? It is soldered to the board and the clamp / holder .is soldered to the board Please respond here and / or to snipped-for-privacy@dslextreme.com
