My laptop is a MSI GX700 (and not a samsung like yours). It's not a problem related to only one kind of laptop.
Currently, my laptop is running with battery plugged since it started. If i watch the historic of the battery in Gnome Power Management ("Historique de l'alimentation" in my french ubuntu), i see a lot of blue and black points meaning that the battery is plugged or unplugged. That's why the screen is flashing. (Low brightness when the battery is unplugged , and full brightness when the battery is plugged). But my battery is always plugged (mean always charging).
=> See my screen shot. (My english is not perfect !)
Tell me if you need more informations. I can provide you whatever you want.
