Did you remove your laptop battery prior to removing the RAM? I do not see that step in your description...
Nevermind, see you had the battery out from a few steps earlier... If this were a desktop, I could probably give some steps. A laptop is a lot more difficult to debug hardware issues, which this seems to be. Check the power connection to the motherboard; make sure the connector attached to the motherboard that the ac adapter fits in is not loose. Also, try with the battery back in the system to see if that makes a difference.
