Doesn't recognize the power adapter. Have replaced battery and PRAM.

Question

Howdy,
I'm having a devil of a time with my Powerbook. It won't recognize a power adapter.
It won't charge my battery.
Won't run when plugged into the power adapter.
The only way it works is for me to charge my battery in my girlfriend's Powerbook and then sprint through any work I try to get done.
I've replaced the PRAM with twice. (one i bought and the other I took from my girlfriend's which I 100% know to work) It didn't make a difference.
Below is the info from the system profiler "System Power Settings"

Welcome to the Apple discussions.
There's only 4 components in the charging circuit: power adapter, DC-in card, battery, and logic board. Do you know for a fact that your power adapter is working? If yes, then not running on the power adapter says either the DC-in card is bad (the card that has the jacks on the left side of the computer) or it's a logic board issue. Is the female jack where you plug the power adapter in visibly damaged, loose, or the case around the socket damaged? If the socket is wiggly loose, likely a new DC-in card is in order. Does the power adapter light up at all when you plug it in?
We had a similar, but not exact, situation recently on one of our Powerbooks, and ended up taking it to the Apple store, where they sent it to the Apple depot for repair. They replaced the logic board and put a new battery in. The Depot service returns the machine with anything needing repair, repaired. If everything is in good physical order, ie the case isn't damaged, it costs around $325, which is less than getting a new logic board put in at the store. If the case is damaged, a trip to the Apple depot costs more. A new DC-in card card + installation by Apple runs around $130, give or take. Used DC-in cards run around $75-$95 if you want to install it yourself.
