Portege Z30A won't run on battery after port replicator died

Hello all,
looking for suggestions. My port replicator died while the laptop was connected to it. I didn't see it happen. Note that this laptop uses the old style multi-pin connector on the bottom of the computer that locks into the replicator.
After ejecting the computer, it will only run with the external power supply connected. Will not boot at all from the internal battery. With the external ps connected, the battery indicates a full charge condition showing 100% when I look at it via the battery/ps icon on the toolbar so I'm assuming it's charged.
Could this be a situation where some kind of reset is needed or have I damaged a circuit?

For the benefit of any found in this situation, I fixed the laptop issue by opening up the case and disconnecting the battery multi-pin connector from the motherboard. I fired up the computer with the power supply and then plugged the battery connector back in. (maybe not the best idea with the power on and the case open). However, after doing this, I disconnected the power supply and the unit remained on.
My best fixed it guess- when the port replicator went belly up, there must have been a "logic state" that remained in play so that the laptop still "thought" it was connected to the port replicator so the internal battery was switched out.
Since then, I charged the battery to full and it runs just fine. Port replicator is dead
