Yes. Removed the battery as well as the mobo jumper. (However, I had to use a paper clip to bridge the gap between the pins since I did not have a jumper.) Still get those debugging lights which makes me think something weird happened with the RAM... The Led light flickers to the CPU one as well, but when I install one ram stick in slot 4, it stays purely on the RAM light. When I move the ram stick to other dimm slots, I get the RAM/CPU lights (again, the CPU light only flashes on, then goes back to the RAM light but keep flashing back and forth)
