This is what I just got. I have the battery fully charged.

As you can see, the thing is, that the status of the AC Adapter isn't being picked up by the computer, and thus, isn't telling the computer that the status of the battery might change. For example, the other day I had full battery, disconnected the AC Adapter, and forgot about it.What happened was, as there was no change in the status, the indicator never showed up that the battery was running low, resulting on the computer shutting down because it had no more energy.

Anything you might need, please tell me.
