When you removed the CMOS battery did you also remove the main battery and then hold the start button for at least 15 seconds?

Test the memory modules

Remove both memory modules. Put one of them in the slot closest to the center of the notebook and try booting again. If no positive results remove that module and try the other one in the same position.

Post your results here in your thread.
