I have a serious issue, too. It has no power. The blue-illuminated plug-end (from the power brick) will go out when I plug the power into the laptop. No power at all. When I unplug it from the laptop, and re-plug the DC brick into an ac outlet, the blue tip (that inserts into the back of the laptop) will stay illuminated until I insert into the laptop. It's like the laptop power-input connector is shorting the power brick.
