Dell Inspiron 6000

I did about 10 inspiron 6000 laptops last month and this is the first for October. It's always hard to tell if a laptop has this known issue or if a manufacturer like dell makes so many of these laptops and problems are bound to happen with that type of volume.
You could wiggle the jack to make it charge and the data pin would show the correct wattage. On these dell jacks they use a "data" pin on the center of the ac adapter tip to designate what type of adapter it is. When you go into bios it will say 90 watt (PA-10), 65 watt (PA-12) and so on. Sometimes the data pin goes bad and when that happens it won't charge the laptop but will power it. The bios will say "unknown" ac adater.
When the laptop was torn down it had the two back voltage pins that were slightly burnt keeping the laptop from charging without a wiggle. The jack, as always, was replaced with a brand new foxconn jack and the laptop charges fine again.
