The story short of my request is this:
Blinking charger, known working, DC jack didn't fix.. now what
The laptop will not take power beyond the jack. I have no way of diagnosing where the problem is on the board. I'm only damaging it further by trying to resolder leads to the jack's location.
Does anyone know of a way to either charge the battery outside the laptop or splice in the charger to the battery contacts? I know everything else works because it will work off a charged battery.
