You did try to remove the AC and plug it back in 1 min latter ?

NOT OK. The last full is higher then the maximal capacity. Thatīs not  
normal.

Go into the BIOS, unplug the AC and let it run. Ignore the beeps, just  
wait for till it runs out.

I think the battery is charged, but the controlcircuit is toast. Maybe a  
full unload/load cycle may cure it.
