Blinking charger, known working, DC jack didn't fix.. now what

I have a non-chargable n10j.
I know it works because a different asus battery when installed sideways will operate the netbook fine. The original battery must have died as it will not power the netbook.

Originally, when plugged in, the laptop would not power, blink, nothing. The charger's LED would blink.
To check if it was the DC Jack, I removed it and soldered wires coming out from the positive and negative leads on the motherboard and connected them to respective inner and outer portion of the charger's plug.
Same problem. Tried moving the positive to it's next closest connection, the neighbouring capacitor. Same problem. There's a cross or something some where down the power distribution.. Don't know where.

What else can I do?? I might try baking it lightly just to see if it will reflow correctly by chance..

 

As an update, baking @ 300/10mins did not work. Tested again, still works. Out of ideas

As a side solution, does anyone know of a battery charger that work outside the laptop? OOrr a way to splice the adapter's lines into the battery connectors??
Thanks
