hp ze4420us

Identical laptop to the article below except this one doesn't have the built in wireless leads.
The jack is completely gone off the back and has no battery life to be able to power on. Once I got the laptop all torn down it had the small burn marks around the voltage pin but the centerpin was completely gone. The ze4xxx series use a three pin, 2.5mm jack that is a pretty poor design. I think a dc jack should have at least five pins for it to be a solid design.
Replacing the dc jack did the trick and the laptop charges and powers on fine.
