After a bit of research on the internet it seems that a blinking green light on a power cord indicates a short. It is the power brick trying to turn on and then the autoshut off kicking in then trying to turn off etc etc.
Unfortunately there isn't much you can do about this issue unless you are a electronic engineer. The only thing you can do is a visual inspection of the parts to insure none of them look damaged and desolder resolder if you think you found the culprit. I would advise not to plug the power into the laptop until after this is done as a short is likely to cause more issues.
My laptop is now sitting in 100 pieces on my kitchen table... soon to be in the garbage bin.
